Shop Floor Management - Quick Guide

Shop Floor Management - Introduction

The most important person who needs to learn from shop floor experiments is the top executive visiting with the sensei.
─ Michael BallĂ©, English Theatre Actor
There are millions of manufacturing and processing businesses around the world. The shop floor is an integral part of those businesses where the real action takes place. A shop floor is responsible to bring out the tangible, usable and superior quality products as per the specifications.

What is a Shop Floor?

The Business dictionary defines shop floor as – “The area in a manufacturing facility where assembly or production is carried out, either by an automated system or by workers or a combination of both. The shop floor may include equipment, inventory and storage areas.”
Shop floor is the place where design specifications are referred, machinery and manufacturing equipment are employed for production, parts are assembled or some raw material is processed. The shop floor is responsible to produce an intermediate or a final product.

Components of a Shop Floor

Here are some important components of a shop floor −
  • Material − This is either a man-made material or a natural resource. Material is a vital part which is used to make or develop some product.
  • Machinery, Equipment and Tools − Depending on the sector of production, there are various mechanical, electrical, electronic and thermal equipment along with various tools used on the shop floor. This factor speeds up the production and improves productivity of the business.
Shop Floor Components
  • Information Technology − Today’s shop floors are equipped with Shop Floor Control Systems (SFC), Manufacturing Execution Systems (MES), Manufacturing Operations Management (MOM) Software, Quality Management Software (QMS), Real Time Data Retrieval from shop floor operations, and other such simulators.
  • Quality Control − When the product is ready, it is required to undergo certain quality tests and criteria to meet customer satisfaction. The Quality Control Section of a shop floor ensures that the product is flawless and up to the customer’s satisfaction.
  • Store Room − It stores spare parts and other such inventories. If there is an appropriate store room layout, its management is shrewd and there are proper SOPs in place, it will certainly reduce operational costs to quite an extent. An up-to-date store helps to predict the budget accurately.
  • Staff − Skilled and experienced staff is a great contributor to successful production on the shop floor. Such staff can work with minimal errors and maximum perfection.

What is Shop Floor Management?

Shop floor management is developing and managing the shop floor operations, inventory, equipment and workers. The following diagram displays the general phases of a manufacturing/processing/assembly business.
Production Phase
A shop floor being the participant of a production phase, its management requires dealing and handling all those factors which are directly involved in production.
As per Mr. Kiyoshi Suzaki (author of The New Shop Floor Management), shop floor management is practicing the three reals −
  • Genba (Real Place) − It refers to the location where the value is created. It can be either the factory floor or a business process.
  • Genbutsu (Real Thing) − The realistic information of all the problems rather than the documented information.
  • Genjitsu (Fact) − Mapping of current problems and their root causes with the help of valid and consistent data.
Thus, Suzaki claims that shop floor management is a closed loop process to monitor the problems onsite as well as to find out and remove their underlying root causes.

Objectives of Shop Floor Management

Here are some important objectives of shop floor management −
  • Routing movement of material on shop floor appropriately.
  • Sequencing the procedures and processes taking place on shop floor.
  • Scheduling of workforce, resources and operations.
  • Finding deviation from standard procedures and processes.
  • Identifying loopholes in shop floor communication.

Benefits of Shop Floor Management

Some vital benefits of shop floor management are given below −
  • Increased operational efficiency through standardization of operations.
  • Reduction in occurrence of errors in work.
  • Revealing of loopholes in production or processes.
  • Increases productivity of the staff.
  • Positive impact on the revenue of a manufacturing business.

Shop Floor Mngmt - Types of Productions

Continuous improvement is better than delayed perfection.
– Mark Twain
Shop floor is a part of machine-tool industries. Every shop floor is different. The type of shop floor entirely depends upon kind of product manufactured, the way a process is executed or the type of machinery used. These production types are classified as per the industry classification in various countries.
Let us understand in detail some more things about the type of productions and the type of shop floors.

Productions as per Types of Industries

To see what all types of products are typically produced, let us first understand the types of industries creating those products. The industries are classified into Primary and Secondary.

Primary Industries

They are the ones which use natural resources and consume them directly. They are further separated into two types −
  • Extracting − These industries involve extracting minerals, water and drawing out different types of products from Earth, Forests and the Oceans. For example, Agriculture, Mining, Lumbering are the businesses belonging to the extracting industry.
  • Genetic − These include businesses working in multiplying animals and plants. Animal husbandries, plant nurseries, fish farming, poultry are some examples of businesses belonging to the genetic industry.

Secondary Industries

They are mainly based on the primary industries for their input resources. They are further divided into the following types −
  • Manufacturing − They use raw material or semi-finished products to transform them into fine products.
  • Analytical − A raw material is analyzed and separated.
  • Assembly − Various components are joined together to create a fine product.
  • Synthetic − Multiple raw products are combined to make a new product.
  • Process − The raw material is passed through various stages to create a product.
Industry Classification
  • Construction − They use products of primary as well as secondary industries to construct infrastructure.
  • Service − These industries do not manufacture any tangible product, but they work on providing intangible products such as experience and satisfaction.
From the industry classification diagram, it is seen that not all industries have shop floors. The work of extraction, genetic and construction industries goes on the sites. The service industry does not have a specific work area; because a service providing business can be executed from a house or can be in the airlines too.
It is the manufacturing industry which has a shop floor as an important part of its execution.

Shop Floor Types

The shop floor types can be understood from the following perspectives −

Product Quantity Perspective

There are two types of this perspective that implies in what quantity the product is manufactured −
  • Mass Production − Mass production involves manufacturing of the standardized products efficiently in large quantities. This is also called as flow production or continuous production. The shop floors for mass production are equipped with assembly lines, machinery and power at a large scale.
    For example − Fast Food Manufacturing. The food items are produced in large numbers, where the cost of manufacturing a single product is very less.
  • Scant Production − It involves creating the product in a sufficient number. It is also called small-volume production.
    For example, production of pure platinum.

Process Perspective

Process perspective is concerned with how the final product is made. Following are the basic types of process perspective −
  • Assembly − On this shop floor, the components are assembled to manufacture a product. These components are already manufactured and can be directly employed as a part of another product. These type of shop floors have assembly lines and a linear movement of the product. The workers stand in that order and perform operation on the product. For example, Car manufacturing, electric or electronic equipment manufacturing shop floors.
  • Analytical Process − It involves breaking of a basic raw material into components, which can be used independently. For example, a refinery breaks down crude oil to get aviation fuel, gasoline, diesel, and petroleum wax.
  • Synthetic Process − It involves using various raw materials or other products to manufacture a good quality product. For example, Shampoo, paints and various cosmetic products manufacturing.
  • Processing − As the name suggests, it involves processing of raw or semi-raw materials through various stages to manufacture a superior product. The material changes its form and appearance while undergoing processing. The processing shop floor contains heavy machinery and expert workers at each stage. For example, textile and cheese manufacturing shop floors.

Machinery Layout Perspective

This perspective of looking at a shop floor tells us about how the machinery is laid out on the shop floor.
  • Job Shop − A job shop is nothing but a processing center. In this type of a shop floor, the tools and machinery is placed as per the type of jobs the expert workers need to perform. The products become finer by going through various job shops. There are multiple jobs done at a job shop and then the product moves ahead to the next job shop. Hence, the sequence of product movement and tracking of progress are vital on this kind of a shop floor.
  • Flow Shop − It is the site where machinery and equipment are placed by the order of processing the product. The product is seen gradually taking shape from where it started till it takes the final shape and is ready. Estimation of product volume is important on these shop floors. If the volume is changed, it is difficult to respond to it and keep the workers’ motivation.
In the next chapter, we will discuss regarding the different types of shop floor layouts.

Shop Floor Management - Layout

Good buildings come from good people and all problems are solved by good design.
– Stephen Gardiner, a British Architect
Shop floor is the production area of any manufacturing facility, which is typically located separately from the main management office of that business. There are no standard or generic shop floor layouts. These layouts are different for every manufacturing, assembling or processing facilities. Various types of products or the processes decide the layout of the shop floor.
Let us know more in detail about the considerations of a shop floor layout.

Guidelines for Shop Floor Building Layout

The Shop Floor building is designed by considering the following guidelines −

Location of the Shop Floor

The shop floor should be located separately within the proximity of the design, engineering and production departments of the manufacturing business. This enables the staff to access the shop floor conveniently.

Shop Floor Infrastructure

It mainly includes the following things −
  • The shop floor building.
  • The built-up or open space for ancillary devices that cannot be installed inside the work area of the shop floor for safety purpose.
  • Cabling, hosing, fans and ACs with their respective electrical connections.
  • Drainage system.
  • Waste management system.
  • Safety devices such as fire extinguishers, etc.
  • This facility can also have eating establishments, restrooms, smoking area, etc.

Health and Safety on the Shop Floor

The shop floor should be designed with the following −
  • Air ventilation in the work area.
  • System to dispose solid and liquid waste.
  • System for readiness to any fire hazard.
  • System to provide first aid and tackle medical emergencies.
  • Housekeeping for clean and neat shop floor.

What is a Shop Floor Layout?

The primary objective of a layout is to demark the entire shop floor area as per the tasks which are done there. Along with demarking, the layout should help in making it simpler for the workers to locate machines, tools, equipment and other staff on the shop floor. The following illustration is how a shop floor is generally laid out.
Work Area

Why Do I Need a Proper Layout of a Shop Floor?

Layout of a shop floor directly influences the factors contributing the production. Here are some prominent reasons for why one should bother about the layout −
  • Layout influences the productivity of the workers.
  • It helps to maximize the use of tools and machines.
  • It decreases the loss of property because of undue handling of tools and machines.
  • It minimizes health hazards and material handling.
  • It maximizes the utilization of space.
  • It maximizes the inventory control of the shop floor.

Production Space Layout

Adequate production space on a shop floor avoids crowding and cluttering, as well as limits any potential damage which might happen due to accidents. The shop floor infrastructure should be designed by considering the following issues −
  • The number of staff and workers.
  • The number of machines and their respective sizes.
  • Scope, size, and sequence of production.
  • The number of tables, cabins and work-benches required on the shop floor.
  • Floor space for placing worker’s tools and personal articles such as helmets, uniform and goggles.
  • Adjacent facilities such as eating spaces, restrooms, smoking areas, which greatly impact the work performance of the workers.
  • Adequate space and pathways to the facilities, entry and exit routes to the work area.
  • Additional place for new machines, product design or increased volume of production.

Types of Production Space Layout

There are two main types of layouts which are as follows −
Product or Assembly Oriented Layout − This layout is designed in a linear fashion. The work stations or work benches are located in a sequence where products manufacturing is carried out one step after the other. This layout is excellent for the mass production. If there is a demand to change the product design or appearance, then this layout cannot address the demand smoothly.
Assembly Oriented Layout
Process Oriented Layout − A group of machines and tools that perform similar or all functions required to complete a single stage in a process are placed together in this layout. This layout permits the flexibility to manufacture different products at the same time. Its design needs careful study of production planning and material handling sequence.
Process Oriented Layout

Shop Floor Inventory, Equipment and Storage Space

While setting up a shop floor, one needs to contemplate on the following points −

Shop Floor Inventory

A shop floor inventory aims to minimize the average cost as per the time as well as satisfy the demand of a product. The cost of keeping inventory per year is about 20% to 30% of its original cost, hence it is good for the shop floor managers to keep the inventory as less as possible. Ideally, there should be zero inventory.
The following points matter to cater inventory −
  • Stock turn over − It should be performed at least four times a year.
  • Stocking − Little extra stocking of the material caters the unexpected demand of the product.
  • Sequence − The flow of material within the shop floor. The sequence should be as short as possible.

Shop Floor Equipment

This equipment helps the workers make the best of products. They make the manufacturing efficient and increase productivity. The equipment can be purchased or leased depending on the length of time and the activities it will contribute. The shop floor should accommodate the necessary equipment smoothly.
Depending on the type of shop floor layout, the number of work stations vary. Industrial work stations include work benches, desks, testing and assembly work benches, technician’s and computer work benches to name a few. They also include conveyer belts and work stands.

Shop Floor Storage Space

This is required to keep the raw material as well as to keep the finished products. The space also includes lockers, racks and shelves. The storage space must be adequate for the staff to move around. It should permit to place the loose property safe and organized.

Places for Shop Floor Staff Facilities

The workers should be provided with various necessities such as cafeteria, rest rooms, first aid, and smoking area. These facilities impact directly on the performance of the staff on the job. These facilities should be set up at appropriate locations with adequate space, so that they do not interfere the usual manufacturing work flow. The facilities for workers and other staff members are set as per the industry standards.

Shop Floor Management - Process Flow

We enjoy the process far more than the proceeds.
– Warren Buffet
The objective of a process flow management on the shop floor is to support consistent development of procedures while developing a product. The shop floor processes include manufacturing, assembling and processing the products along with controlling the tasks associated with it.

Shop Floor Production Methods

Majorly, there are three types of shop floor production methods −
  • Repetitive
  • Discrete
  • Process
Let us now understand each of them in detail.

Repetitive

This type of production is also called as Mass Production. In this production type, same or similar products are manufactured in large number over a length of time. The product manufacturing has a predefined sequence, which needs to be followed exactly as it is. The routing of repetitive production is also linear and simple. The cost of production is observed as per the time spent on it and production is controlled based on the length of time. For example: Manufacturing of soap bars.

Discrete

In this type of production, specialized products are manufactured on demand. Tailor made articles, custom built machines are manufactured in discrete production. The sequence of operations and workstations is variable. Production is controlled based on the demand. The cost of production is calculated at the time of reception of order; not as per the time spent. The resulting products are individually identifiable and different from the process manufacturing products. For example: Manufacturing of smartphones, computers, etc.

Process

In this production type, the raw material are the products which undergo different phases. For example: Chemical, Pharmaceutical, Food and Beverages, etc. fall under the process type of production method.
There are two types of processes −
  • Batch Process − In this process, bulk of the material in batches is processed. One batch of a limited number of items or quantity is processed at a time. Till the current batch of material is finished its processing, the other batches need to wait.
  • Continuous Process − It involves continual processing of the material to create a product. It saves waste, energy and costs. It adapts itself to customer needs more effectively and smoothly.

Assembly Types

Here are the most common assembly types −

Assembly Lines

Assembly type can be categorized depending upon the type of assembly line as follows −
  • Standard Assembly − It is a semi-automated assembly line. The products-in-manufacturing are placed on the line. The workers and equipment remain stationery on either side of the line to work on the product and the product moves through the line from start to end, often called as a cycle.
  • Modular Assembly − It involves advanced assembly lines working in parallel and meeting at the final assembly line. These assembly lines achieve parallelism in manufacturing to some extent. They are expensive, but save a lot of time.
Assembly Lines
  • U-Shaped Assembly − This is a line with a curve along which the workers stand and machines work on the product-in-manufacturing. It provides better communication among the workers. They can also see what is coming to them at what speed. This assembly line enables to produce products with variable designs simultaneously.

Assembly Joints

The following type of joints decide the type of assembly.
  • Hardware Assembly − It uses hardware or fasteners such as screws, nuts, and bolts to join various parts together. It allows flexibility to remove the parts or change them. For example, motor chassis assembly.
  • Welding Assembly − Multiple metal parts are joined together, which appears as one part after welding. It is a permanent assembly. For example, wrought iron based furniture assembly.
  • Soldering Assembly − It uses a filling metal, which is melted to a certain temperature by heating. This metal is used to bind two components together. For example, soldering of electronic parts and jewelry.

4P Management Model for Shop Floor

As per Jeffrey Liker, the author of “The Toyota Way”, the 4P process model of shop floor can be viewed as shown below.
4P Management Model
The lowest level Philosophy pertains to the long term thinking such as a mission to contribute to the growth of employees, organization and to the economy.
The second level Process is concerned to improved processes by reducing machine downtime, removing waste and increasing the overall productivity at the shop floor through efficient processing practices.
The third level People and Partner mainly investing resources in people who work for the business such as employees, suppliers and partners for the growth of the business.
Since shop floor management concerns with finding a solution to the real-time problems and incidences, problem solving is located at the highest level. Problem solving is a continual part of shop floor management to ensure that there are no breaks in production.

What Happens on the Shop Floor?

Apart from the actual handling of equipment and tools, working on machines and doing mechanical jobs, here is what happens on the shop floor on daily basis −
  • Depending on the volume of production a business handles, a single work order or batches of work orders are created.
  • The work orders are then released to the floor.
  • The material is issued as per the requirement.
  • Purchase requisitions are generated for out of stock material.
  • Purchase order receipts are recorded.
  • Labor working hours are recorded.
  • Subcontracted services are received.
  • Leave applications are treated.
  • Soft or hard copies of reports are generated for management review.
  • Completed jobs are closed.
In the next chapter, we will understand in detail regarding Shop Floor Management Setup.

Shop Floor Management - Setup

Management is doing things right. Leadership is doing right things.
– Peter F. Drucker, an American Management Consultant
A neatly setup and well-organized shop floor can be easy to manage. It saves time and efforts because the workers find their tools at a proper place, equipments are in a healthy condition, floor space is clean from oil, dust or grease, and the shop floor control systems are perfectly tuned to the production operations. Neatness and orderliness on the shop floor leads to happy workers and supervisors, which generates increased productivity. In addition, it sends a message about product quality to the clients and the customers.

What is Shop Floor Management Setup?

The shop floor set up includes setting up machines, assembly lines, tools, storage area, scheduling of operations and setting up control system that records the processes.

Setting up Machines, Equipment and Tools

Machines and equipment are arranged for optimum work flow. Space between machines is kept adequate so that there would be minimum conveying, minimal waste with maximum safety. The loose tools should be placed in the area which is specially allocated for tools, so that they do not go missing. The tools are also arranged as per their size and other conventions, then it is easy to find out a missing tool faster.

Setting up Assembly/Production Lines

This type of assembly line should be wisely selected depending on the type of production. The production line processes are closely observed to simplify complicated processes and remove unnecessary processes. The area around the assembly line is kept adequate for the movement of workers, inventory and equipment.

Scheduling Shop Floor Operations

Since the shop floor works 24X7 in three shifts, scheduling is vital for a seamless production process. The scheduling of operations includes machine scheduling such as single and parallel machines, job scheduling that requires to schedule the jobs as per their level of urgency and scheduling of workers and staff as per their availability.

Setting up Storage Area

The storage area of the shop floor stores raw material, the intermediate material and the inventory. The storage of inventory should be well organized and well-documented. The material of the same type should be grouped together. The material required for the same process or task should be placed together.
The ready product should be placed on the racks or in cabinets. The track of the material and the ready products should be recorded.

Work Center VS Resource Center

Let us now understand the difference between a work and a resource center.

Work Center

A Work center is a section of production line where the workers carry out manufacturing activities or all the tasks associated with a single process. For example, the car production line would have multiple work centers such as welding, fixing, gear-box and painting.
Each work center has skilled workers, equipment, raw material and work area allotted to it. The work centers are expected to perform various work associated to a single type of task or a process.

Resource Center

A resource center provides information on the business, flagship product and other product variants, brand and other activities. It keeps a collection of online product catalogues, instruction manuals, user guides and details of a product dealer. The resource center also publishes news and white papers.

Shop Floor Management Activities

Following are two fundamental activities the manager carries out on the shop floor −
  • Daily Activities
  • Continual (Kaizen) Activities
Let us now discuss them in detail for better understanding.

Daily Activities

The daily activities that a manager does on a shop floor includes:
  • Daily team meetings.
  • Directly manage all the resources at hand.
  • Gemba walk: Managers walking on the shop floor for monitoring if everything is going on smoothly or not, increases the morale and safety of workers and in turn the productivity.
  • Practical problem solving and taking corrective action on faulty machines.
  • Housekeeping for cleanliness and orderliness.
Daily Activities

Continual (Kaizen) Activities

These activities include −
  • Addressing current problems, anticipating any future problem related to processes, activities, methods, machines and workers.
  • Taking preventive measures on the potential upcoming problems to avoid loss of time and safety.
  • Continually updating self on knowledge about new machines, tools and techniques for improvement of the shop floor is essential.
  • Notifying and discussing with the higher management about any major change if required on the shop floor.
  • Keeping liaison with workers, subordinates and suppliers.
In the next chapter, we will discuss in detail about Shop Floor Control.

Shop Floor Management - Control

Humans are the worst control system to put in front of a car.
– Peter Diamandis, a Greek–American engineer, physician, and entrepreneur
Shop floor control has a crucial role on the shop floor as it enables the management to see what is happening in real time. Shop floor control is necessary for any manufacturing, assembling or processing business. Shop floor control systems can increase the productivity substantially and in turn the ROI of the enterprise.

What is SFC and SFCS?

Let us now understand in detail about Shop Floor Control (SFC) and the Shop Floor Control System (SFCS).

Shop Floor Control (SFC)

It is a system that has methods and tools, which are used to track, schedule and report progress of the work in a manufacturing unit.
The better the shop floor control, the better the inventory and operations control, and the better is the productivity of the workers. Performance and ROI of a manufacturing business varies directly in proportion to the shop floor control.

Shop Floor Control System (SFCS)

It is a software system used to track, streamline and report the work progress in a manufacturing unit. SFCS can evaluate a portion of an order or an operation that has been completed. It provides the insight into the work in process. These insights are useful for planning the resources, evaluating the inventory, and increasing the staff productivity on a shop floor.
For example − A few popular shop floor control systems which help to capture and monitor shop floor information in detail are −
  • Sage 500 ERP
  • ShopFloor
  • JD Edwards World Shop Floor Control system.

Objectives and Benefits of SFCS

Let us now discuss the Objectives and the Benefits of the Shop Floor Control Systems.

Objectives of Shop Floor Control Systems

Here are some important objectives of SFCS −
  • To provide total control over shop floor activities, inventory and resources.
  • To streamline the operations and reduce production cycle times.
  • To provide real time data related to activities, inventory and resources.
  • To provide accurate updates on machine usage, man hours for each staff member, payroll calculations and timely alerts to potential problems.

Benefits of Shop Floor Control System

Here are some prominent benefits that SFCS offers −
  • It is paperless.
  • It provides total visibility to what happens on the shop floor.
  • The supervisors and managers find themselves empowered as the SFCS facilitates them to monitor complete range of operations and activities carried out on the shop floor.
  • It alerts the staff member regarding any upcoming problem beforehand to limit or eliminate the loss of property or time.
  • It provides real time data, which is quantifiable and actionable.
  • It provides planning and scheduling of shop floor operations thereby increasing efficiency of workers.
  • It eliminates the errors in calculations machine time, man hours, worker payrolls and much more.
  • It reveals operational vulnerabilities and staff as well as resource related problems and helps to address them in time.
  • It makes decision making easy for the management by providing reports.
  • It drives the ROI of a manufacturing business.

Elements of SFCS

There are four fundamental elements of shop floor control system. They are −
  • Communication − Exchange of messages within the SFCS.
  • Data Management − Storing, Rewriting, Deleting, appending and Recording the real-time data.
  • Processing − Accessing data and processing it for quantifiable readings and calculations.
  • User Interface − Easy to learn, user friendly, clear instructions and notifications with touchscreen UI that speeds up the tasks.

Key Features of SFCS

Here are some vital key features of SFCS −
  • Flexibility − The SFCS should accommodate changes in volume of product or the product itself.
  • Inter-operability − The SFCS should be coherent enough to work on various hardware and software platforms.
  • Portability − The SFCS should be able to work cross-platform. If it is working on a certain hardware platform and operating system, then it should also work on another hardware platform and operating system, which can be achieved by standard programming language and standard operating system calls.
In the next chapter, we will discuss in detail what Shop Floor Control is.

Shop Floor Management - Communication

The art of effective listening to clear communication, and clear communication is necessary to management success.
– James Cash Penney, an American Businessman
Mistakes and errors due to lack of clear communication can turn out expensive on the shop floor. Poor communication also leads to wastage of man hours, machine time and above all the efforts. The communication gaps should be ideally zero on the shop floor as communication plays an important role in obtaining high operational performance and quality management.

Why Does Shop Floor Communication Matter?

The workers and other staff members on the shop floor work in a cooperative environment of humans and machines. Thus, the staff not only exchanges the information, but also their feelings. The tasks on the shop floor majorly require a collective effort of the manager, supervisor, the workers and machinery. Hence clear communication and accessing is a much-required information which is important among them.
In addition to all the above-mentioned factors, poor communication on the shop floor can lead to loss of business property, efforts and time. It can also lead to the loss of future business. Considering all these risks, it is certain that the communication on the shop floor matters.

Type of Communication on a Shop Floor

There are two typical types of communication taking place on the shop floor −
  • Machine to Machine (M2M) − It is provided by automation controllers to enable efficient process execution at machine level. In this type of communication, the devices communicate directly to each other using wired or wireless communication channel and dedicated protocols. Sensors and relays, database, application software and network enables this sort of communication. Latest M2M communication systems also transmits data to the personal mobile devices of the managing staff.
  • Machine to Business (M2B) or Machine to Enterprise (M2E) − It is provided by automation controllers to enable efficient process execution at management or enterprise level. In this case, the application software at the vendor side accesses shop floor data stored on the database without getting into the complex shop floor processes.

A Manager’s Role in Shop Floor Staff Communication

The shop floor manager needs to communicate to the shop floor staff to know the pulse of production. A shop floor manager must do the following things for better rapport with the staff −
  • Find out time for Gemba walk, regardless of all other numerous activities.
  • Remain accessible and reachable for the subordinates.
  • Visit the work stations and assembly lines to observe what is happening in real.
  • Bring the staff members to speak about their problems.
  • Build trust of workers and other staff members.
  • Double the listening time with respect to the talking time and show genuine interest in what they talk.
  • Study others’ body language; gestures and expressions because even if a person stops talking, he cannot stop behaving.
  • Be cordial to the staff members and workers.
  • Train the workers and other staff members regularly to let them learn changes in technology, processes, and the work environment.
  • Meet the subordinates weekly for some time for informing updates, discussing issues and brainstorming.
Staff Communication

Shop Floor Etiquettes for Managers

Manners and etiquettes can boost the morale of shop floor personnel as well as bring consistent success in lean manufacturing process. The following etiquettes are important for the shop floor managers −
  • Treating other staff members respectfully. Not looking them down upon irrespective of their junior rank.
  • Announcing regular or special visits.
  • Keeping the hands out of pockets always while Gemba walking.
  • Attending genuinely and empathetically to what subordinates say.
  • Letting the subordinates know that their input to management is valuable.
  • Understanding the local and the official language, and their uses as per the requirement.
  • Returning telephone calls and emails as soon as possible for complete communication.
  • Speaking clearly and if required a little loudly to be audible in the shop floor’s noisy environment.
  • Appreciating the workers and subordinates in work for their ideas and hard work.
  • Removing friction among workers and other staff members by allowing them to access the right information.
  • Thanking the staff, wishing them good day and showing gratitude for their patience and cooperation through some special visits.
  • Not belittling someone’s suggestions or opinions.
  • Not drinking or eating while on the shop floor.
  • Not touching anything unless the manager knows what he/she is doing.
  • Not interrupting the speaker.
  • Not interfering the ongoing task. Not overshadowing the operations taking place due to your presence.
  • Not taking pictures or videos without permission of higher authorities or without prior notice to the shop floor personnel.

Shop Floor Etiquettes for Supervisors and Workers

The supervisors and workers should follow the etiquettes given below −
  • Arriving at the shop floor on time and sober.
  • Wearing safety equipment while being on the job.
  • Keeping the shop floor tools, equipment, and other property at the dedicated area before leaving the shop floor.
  • Not wearing lose garments for safety purpose.
  • Not bringing drinks or food on the shop floor.

Shop Floor Communication Systems

Here are some popular communication systems on the shop floor −

MConnect

It is an open-source royalty-free manufacturing protocol designed to connect manufacturing equipment on the shop floor to the outside world easily. It uses well-established Internet standards such as HTTP and XML.

NC Simulation

It creates shop floor documents and reports automatically in HTML and PDF formats during simulation. The 3D reviewer tool of this is very helpful while communicating on the shop floor as well as with the vendors and customers.

Shop Floor Connect

It provides a direct connection to each machine in the shop. It has elegant touchscreen easy user interface. The shop floor operators can access data directly by locating the correct data files required for production such as CNC programs, lists of tools and drawings.

Shop Floor Management - Organization

In a balanced organization, working towards a common goal, there is success.
─ Arthur Helps, an English writer
A shop floor is a small organization within a large one. It is a subset of the business enterprise where all the tangible production takes place. Within a shop floor there are various smaller departments, operations and responsibilities.

Shop Floor Departments

The following departments work under a factory or a shop floor −
  • Purchase Department
  • Production Department
  • Operations Department
  • Quality Control Department
Let us now discuss in detail about each of these departments.

Purchase Department

It is responsible for recognizing the need to purchase, receiving quotes or proposals and procuring the required material. Purchasing department determines the vendor’s compliance, deals with suppliers and assesses incoming material’s cost and quality. It finally deals with the accounts department for actual purchase.

Production Department

It works in three stages as shown below −
  • Pre-production − Preparing the material for use by inspecting, curing or cleaning.
  • Production − Using the material for actual production/assembly/processing.
  • Post-production − Sorting the finished products as per the types/variants and packaging them.
Production department is responsible for creating/building products with different variants if required. It also strives to manufacture or assemble with ideally zero flaws.

Operations Department

This department is responsible for directing and developing. It determines processes and product volume, plans and controls shop floor workflow and steers the shop floor operations. It is also responsible for delivering results without time delays.
Operations Department

Quality Control Department

It is responsible for testing the product against criteria set for optimum quality. It ensures that the product is not contaminated or damaged. It approves or rejects raw material, finished product or packaging material. It reviews all records for quality and completeness of order before sending to dispatch or distribution. This department investigates the customers’ complaints and maintains a rapport with the vendors.

Shop Floor Staff Members

There are several personnel who will be working on the shop floor, the most significant ones are as follows −
  • Shop Floor Manager
  • Supervisor
  • Foremen
  • Workers
  • Operatives
Let us now understand what are the roles and responsibilities of each of these personnel.

Shop Floor Manager

The manager is responsible to manage staff and resources on the shop floor. He is also responsible for training the new employees and subordinates, introducing them to the work culture and solving their work-related problems. The shop floor manager needs to work hand in hand with the production manager.

Supervisor

The supervisor is responsible to keep the track of the operations on the shop floor and bring it to the notice of the concerned person, if something goes wrong. He works as an assistant to the shop floor manager and his main duty is to get the things done.

Foremen

They get their position by the virtue of experience in the job instead of through formal training. They do same tasks as supervisors do under the shop floor manager. They teach others how to perform a task correctly and efficiently. They read and follow designs or sketches. They can suggest changes if necessary. They contact private vendors for machinery and equipment. They also are the point of contact when working with other departments or agencies outside the organization.

Workers

They are the members who make things happen. The workers are responsible to get the things produced by assembling, tweaking and turning, sorting, packing and getting ready for distribution. The workers directly handle tools and machines to manufacture the product.

Operatives

They are the workers, who are expert in some specific function. They are a part of workers team. They need to undergo training on operating a machine or learning a skill. They also need to take basic education formally.

Manager’s Role in Staff Training

The manager is responsible to conduct trainings of his subordinates. The manager should adhere to the following protocols −
  • Take the staff training as a constructive event instead of looking at it as a machine downtime period and loss of production.
  • Develop a collection of knowledge bank what includes training resources such as videos, recorded seminars, books and instruction manuals.
  • Let the staff members access the knowledge bank easily.
  • Develop a training course structure as per the staff’s cognitive level.
  • Contact outside training agencies for training his staff on special purpose machines or simulators.

What Happens When a Shop Floor is not Organized?

Following are some of the most common consequences of an unorganized shop floor.
  • The workers don’t find tools and equipment in place.
  • The equipment or machinery start losing on their health.
  • The shop floor space, working time and effort are wasted.
  • Furthermore, it becomes difficult to quantify the waste.
  • Material or ready product becomes prone to damages.
  • It creates danger of accidents.

The 5-S Program for Shop Floor Orderliness

The 5-S program is a methodology to make the shop floor activities leaner. It was developed in Japan to empower the Just-in-Time (JIT) manufacturing. It includes five Japanese words depicting the guidelines to keep the shop floor well-organized with minimal waste and maximum efficiency.

Sort (Seiri)

This means keeping only what is required and eliminating what is not from the work area. Some of the most common instances are as follows −
  • Remove all the parts which are not in use.
  • Reduce or eliminate obstacles in the workplace.
  • Place unnecessary items that cannot be removed immediately in the red-tag area.
  • Prevent accumulation of unnecessary items in the work area.
  • Avail only as much material as required for immediate work.
  • Establish common area of exchange for tools and information.

Shop Floor Management - Safety

Working safety may get old and so do those who practice it.
─ Unknown
There are numerous tools, equipment and heavy duty machines on the shop floor. The shop floor staff encounter these daily, exposing themselves to the threat of accidents.
There is another saying, “A wrong tool in the right hands is far better than the opposite.” Apart from the unforgiving machinery, equipment and tools, it is sometimes the carelessness or bad intentions of a human who handles them.
Let us understand in detail regarding shop floor machinery, tools and safety.

Dangerous Machinery on the Shop Floor

A shop floor keeps several sharp tools for cutting, pressing, filing, fixing, etc. It keeps electric equipment for various assembly types such as welding or soldering. A shop floor also has machines with running belts and wheels, revolving shafts, couplings, spindles, lifting and moving machines along with their attached moving parts. These machines can pose a threat of hurting their operators if proper care is not taken while working with them.
To keep oneself safe from the threat of getting hurt, the workers need to possess thorough knowledge of operating the machine.

Typical Safety Guards for Shop Floor Machines

There are a range of safeguards used for shop floor machines, some of the most important ones are listed below −
  • Fixed guard − It is a mechanical guard, which is fixed on the machine. It prevents access to the dangerous parts of the machine. It is a reliable guard with minimal maintenance.
  • Interlocking guard − It can be a mechanical, electrical, pneumatic or the combination of all. It is designed in such a way that the machine cannot start if the guard is open. It is very useful where feeding of raw material and withdrawing of products is required on regular occasions.
  • Automatic guard − It is used on machines which need manual feeding of materials such as drop hammers. The automatic guard moves at a faster rate than the point of operation. It is suitable for those machines working with rhythmic actions with the gap of a couple of seconds in its recurring operation. It is not good for high speed operating machines.
  • Trip guard − It consists of a grid or frame connected to a mechanism, which can stop the machine by applying a brake. Trip guard can also come in the form of photoelectric curtain between the dangerous part of machine and the operator.

Safeguards for Shop Floor Workers

There are a number of safeguards used by the shop floor workers and other staff. Some of the most commonly used protection ware that is required to be used on the shop floor are given below −
  • Safety Helmets − It comes with a plain or with a transparent face shield. The face shield under every circumstance guards the face while welding, cutting or performing similar operations where tiny pieces of material are expected to chip off. They also come with a detachable head lamp that helps the worker to see if there are any dark spots.
  • Safety Shoes − They come with closed toes and a thick sole, which make the grip of the feet firm on any surface. They protect the feet from potential injuries on the shop floor.
  • Gloves − The gloves protect the palms and hands while a worker is assembling the metal parts by welding or cutting metal using the revolving saw. They also protect the workers’ hands from harmful substances and chemical or any thermal burns.
Safeguards
  • Industrial Jacket or Coat − The industrial jackets or coats are thick and bright-colored. They are made of canvas, rubber or some other material that resists fire and chemicals. They are available in various lengths.
  • Hearing Protection − It comes in a form of ear plugs to as sophisticated as a pair of caps with a headband. It is the most important protective ware that saves the workers’ vital sense of hearing.
  • Protective Goggles − It comes with adjustable frames and anti-fog glasses of various colors. It is made of scratch resistant material such as polycarbonate for increased durability. It saves another vital organ, the eyes from burning or getting hurt in any way. It also protects from vision impairment due to continual exposure to bright light.
  • Dust Mask − It is made of cotton. It protects the worker’s respiratory system from airborne particles created at the time of grinding and drilling.
  • Emergency Stop Control − It is a control mechanism to halt the operating machine completely. This stop control overrides all other controls to stop the machine. It also needs a separate mechanism that can start the machine again.
