Zero Defects

In other projects we have witnessed the significant impact that Zero Defects programs can have on a manufacturing organization. Zero Defects, also known as "Zero Quality Control" or "ZQC," is a quality improvement philosophy that seeks to eliminate defects in the production process. This philosophy has its roots in the Total Quality Management (TQM) movement and has been widely adopted by many manufacturing organizations.

The Zero Defects philosophy is based on the belief that quality should be built into every product, from start to finish. The goal is to eliminate defects and ensure that products are produced to the highest standard, meeting or exceeding customer expectations. This approach to quality focuses on the entire production process, from raw materials to finished goods, and encourages all employees to be actively involved in the quest for zero defects.

One of the key benefits of a Zero Defects program is that it helps to create a culture of continuous improvement. Employees are encouraged to identify areas where defects are occurring, and to work together to eliminate these issues. This creates a sense of ownership and engagement among employees, which in turn drives improved performance and results.

Another key benefit of Zero Defects is that it reduces the costs associated with rework and product defects. Defects in the production process can lead to increased costs, such as scrap, waste, and retooling. By reducing or eliminating these costs, organizations can improve their bottom line and remain competitive in their industry.

The key to success with Zero Defects is to have a well-defined process in place. This process should start with defining the standards for each product and then identifying the critical-to-quality characteristics that must be met. From there, a detailed process map should be created that outlines the steps involved in the production process, from raw materials to finished goods. This process map should also identify the potential sources of defects and highlight the steps that need to be taken to eliminate these defects.

Once the process map is in place, the next step is to implement the Zero Defects program. This involves training employees on the Zero Defects philosophy, as well as the process map and the critical-to-quality characteristics. It is also important to provide employees with the necessary tools and resources to identify and eliminate defects. This may include things like checklists, forms, and software programs.

In addition to training and tools, it is also important to have a robust feedback and continuous improvement process in place. This can include regular quality audits, customer feedback, and employee suggestion programs. The goal of these programs is to identify areas where defects are occurring, and to work together to eliminate these issues.

Finally, it is important to track progress and measure success. This can be done by tracking key performance indicators (KPIs), such as the number of defects, scrap rates, and customer satisfaction levels. By tracking these KPIs, organizations can determine whether their Zero Defects program is having a positive impact and make adjustments as needed.

In conclusion, Zero Defects is a powerful tool for organizations looking to improve the quality of their products and processes. By eliminating defects, organizations can improve customer satisfaction, reduce costs, and remain competitive in their industry. The key to success with Zero Defects is to have a well-defined process in place, and to actively involve employees in the quest for zero defects.

Set up time

The term "set up time" refers to the amount of time it takes to transition a manufacturing process or production line from producing one product to another. This time includes all the tasks and activities that must be performed in order to prepare the line for the new product, such as cleaning and changing tools, adjusting machinery, and organizing raw materials and supplies.

Set up time has its origins in the field of manufacturing, where reducing the time required to change over from one product to another has been a critical factor in improving efficiency and productivity. The idea behind reducing set up time is that the less time a production line is idle, the more products can be produced, and the more efficiently the production process can run.

To improve set up time, organizations can use a variety of methods and techniques. One approach is to standardize set up procedures, so that the same steps are followed every time a change over is performed. This standardization helps to eliminate waste, reduce the risk of errors, and speed up the process.

Another approach is to use technology to automate and streamline set up procedures. For example, a company might use barcode scanning to quickly and accurately identify the right tools and supplies for a particular change over, or use robotic arms to change tools and adjust machinery, reducing the amount of manual labor required.

Organizations can also make use of visual aids, such as standard work instructions, to help workers understand the set up process and complete it more quickly. These instructions can be displayed in the form of checklists, posters, or other visual aids that are easy to understand and follow.

In addition, organizations can work to minimize the number of set ups required by batching products or running them in a continuous flow, which reduces the need to change over production lines as frequently.

Finally, it is also important to involve workers in the process of improving set up time. By engaging workers in the process and soliciting their input and suggestions, organizations can gain valuable insights into how the process can be improved and find new and innovative ways to reduce set up time.

In conclusion, improving set up time is critical for organizations that want to optimize their production processes and improve efficiency.

Push Principle

The Push Principle Concept/Term refers to a production system where material and products are manufactured and moved along the production line based on a predicted demand, rather than actual demand. This system operates under the assumption that the customer demand can be accurately forecasted and the production line can be appropriately scheduled to meet that demand.

However, the Push Principle often leads to negative impacts on operations. One of the main problems with this system is the assumption of accurate demand forecasting. In reality, customer demand is highly unpredictable and can fluctuate rapidly, leading to overproduction and inventory buildup. This excess inventory creates significant problems such as storage and handling costs, obsolescence, and potential quality issues.

Additionally, the Push Principle often results in an inefficient utilization of resources. The production line is designed to produce a set amount of product, regardless of actual demand. This can lead to idle time and equipment, increased energy costs, and reduced production capacity. The production process is also disrupted by production line breakdowns, worker absences, and equipment failures, resulting in increased downtime and decreased efficiency.

Another negative impact of the Push Principle is that it can lead to a lack of focus on customer needs. The emphasis is on meeting a predetermined production schedule, rather than meeting the actual needs of the customer. This can result in an overproduction of products that are not needed, as well as a lack of flexibility to adapt to changing customer demand.

To mitigate these negative impacts, Lean Management experts advocate for the implementation of the Pull Principle. The Pull Principle is a system where production is based on actual customer demand, rather than a predicted demand. This system allows for a more flexible and efficient utilization of resources, as well as a greater focus on meeting the actual needs of the customer.

In a nutshell, the Push Principle can lead to negative impacts on operations such as inventory buildup, resource inefficiency, and a lack of focus on customer needs. Lean Management experts recommend the implementation of the Pull Principle as a more efficient and effective alternative. By focusing on actual customer demand, organizations can achieve greater operational efficiency and meet the needs of their customers.

Bullwhip Effect

The bullwhip effect is a well-known phenomenon that can have a significant impact on the push and pull principles of supply chain management. The bullwhip effect refers to the amplification of demand fluctuations as they move up the supply chain, leading to increased inventory, increased costs, and decreased customer satisfaction.

The bullwhip effect is caused by a number of factors, including demand forecast errors, order batching, price fluctuations, and the use of incentives that encourage suppliers to order more than they need. These factors can cause suppliers to overreact to demand changes, leading to excessive inventory levels and higher costs.

The impact of the bullwhip effect on the push and pull principles of supply chain management can be significant. The push principle is based on the idea that suppliers produce goods based on demand forecasts, and then push the goods to the customer. The bullwhip effect can cause demand forecasts to become less accurate, leading to increased inventory levels, increased costs, and decreased customer satisfaction.

The pull principle, on the other hand, is based on the idea that suppliers produce goods based on actual customer demand. The bullwhip effect can cause suppliers to overreact to demand changes, leading to increased inventory levels and higher costs. This can result in a situation where suppliers are producing goods that are not actually needed, leading to a decrease in customer satisfaction and increased waste.

To address the bullwhip effect, organizations can implement a number of strategies, including improving demand forecasting accuracy, reducing order batching, reducing price fluctuations, and using incentives that encourage suppliers to order what they need, when they need it.

One approach to reducing the bullwhip effect is to implement a demand-driven supply chain management system. This involves using real-time data to better understand customer demand, and using this information to make informed decisions about inventory levels and production schedules. This can help to reduce the bullwhip effect, leading to more accurate demand forecasts, lower inventory levels, and increased customer satisfaction.

Another strategy to address the bullwhip effect is to implement a lean supply chain management system. This involves reducing waste, streamlining processes, and improving communication and collaboration between suppliers, manufacturers, and customers. This can help to reduce the bullwhip effect, leading to improved supply chain efficiency, lower costs, and increased customer satisfaction.

In a nutshell, the bullwhip effect is a well-known phenomenon in lean management that can have a significant impact on the push and pull principles of supply chain management. To address the bullwhip effect, organizations can implement a number of strategies, including improving demand forecasting accuracy, reducing order batching, reducing price fluctuations, and using incentives that encourage suppliers to order what they need, when they need it. By implementing these strategies, organizations can reduce the bullwhip effect, leading to more accurate demand forecasts, lower inventory levels, and increased customer satisfaction.

In the context of Lean management and operational excellence, machine cycle time is a critical metric that can be used to measure the efficiency and effectiveness of a manufacturing or production process.

The basic idea behind machine cycle time is that it measures the amount of time it takes for a machine to complete a specific task or series of tasks. This can include things like setting up a machine, loading raw materials, running a production process, and unloading finished products. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can gain insight into how efficiently the machine is running and identify areas for improvement.

One of the key benefits of measuring machine cycle time is that it can help organizations to identify bottlenecks and delays in the production process. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can identify which machines or processes are taking longer than they should, and then take action to address these bottlenecks. This can include things like improving machine maintenance, optimizing production processes, or identifying areas where automation can be used to improve efficiency.

Another benefit of measuring machine cycle time is that it can help organizations to identify areas where standardization can be used to improve a process. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can identify which machines or processes are taking longer than they should, and then take action to standardize those processes. This can include things like implementing best practices, developing standard operating procedures, or identifying areas where automation can be used to improve efficiency.

Measuring machine cycle time can also help organizations to identify areas where automation can be used to improve efficiency. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can identify which machines or processes are taking longer than they should, and then take action to automate those processes. This can include things like using robotics, using automated inspection systems, or using artificial intelligence to optimize production processes.

Machine cycle time also plays a critical role in analyzing machine’s capacity. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can identify which machines are operating at full capacity, and which ones have room for improvement. This can help organizations to optimize their production processes, and ultimately, increase their overall production capacity.

In conclusion, machine cycle time is a critical metric that can be used to measure the efficiency and effectiveness of a manufacturing or production process. By measuring the amount of time it takes for a machine to complete a full cycle of operation, organizations can gain insight into how efficiently the machine is running, identify bottlenecks and delays in the production process, identify areas where standardization can be used to improve a process, and identify areas where automation can be used to improve efficiency. Ultimately, measuring machine cycle time is a powerful tool for organizations that are committed to operational excellence and continuous improvement.

Standard Layout

Standard Layout: The Key to Unlocking Efficiency in Lean Management

Standardization is one of the fundamental principles of lean management, and it's no surprise that it's also one of the most effective ways to improve efficiency and reduce waste in your operations. One of the most powerful tools in the standardization toolbox is the standard layout, also known as "taikyō-sei" in Japanese.

A standard layout is a detailed, visual representation of the ideal workflow and arrangement of resources in a given area. This can include anything from the placement of tools and equipment to the flow of materials and the location of workstations. The goal is to create a clear and consistent way of working that minimizes waste, maximizes efficiency, and makes it easy for everyone on the team to understand and follow.

One of the most important benefits of a standard layout is that it makes it much easier to identify and eliminate sources of waste and inefficiency. By clearly defining the ideal way of working, it becomes much easier to see where things are going wrong and to make adjustments as needed. This can include anything from adjusting the location of workstations to the flow of materials, to the type and size of tools and equipment.

Another key benefit of a standard layout is that it makes it much easier to train new employees and to ensure that everyone is following the same processes. When everyone is working in the same way, it becomes much easier to share knowledge and best practices, which can help to improve the overall performance of the team.

Finally, a standard layout can also be a powerful tool for continuous improvement. By clearly defining the ideal way of working, it becomes much easier to measure performance and to identify areas for improvement. This can include anything from adjusting the flow of materials to the location of workstations, to the type and size of tools and equipment.

So, how do you go about creating a standard layout? The first step is to conduct a thorough analysis of your current operations. This should include a detailed study of the flow of materials, the location of workstations, and the type and size of tools and equipment. You should also pay close attention to the flow of people and information, as this can have a big impact on overall efficiency.

Once you have a good understanding of your current operations, you can then begin to create a detailed, visual representation of the ideal workflow and arrangement of resources. This should include everything from the placement of tools and equipment to the flow of materials and the location of workstations.

It's also important to involve your entire team in the process of creating a standard layout. This will help to ensure that everyone is on board with the changes and that everyone understands the benefits of standardization.

Once you have a standard layout in place, it's important to monitor and measure its effectiveness on a regular basis. This can include anything from tracking the flow of materials to the location of workstations, to the type and size of tools and equipment. It's also important to involve your entire team in the process of monitoring and measuring performance, as this will help to ensure that everyone is committed to continuous improvement.

In conclusion, a standard layout is a powerful tool for unlocking efficiency in lean management. By clearly defining the ideal way of working, it becomes much easier to see where things are going wrong and to make adjustments as needed. This can include anything from adjusting the flow of materials to the location of workstations, to the type and size of tools and equipment. Furthermore, it is a powerful tool for training, knowledge sharing, and continuous improvement. If you're looking to improve efficiency and reduce waste in your operations, a standard layout is definitely worth considering.

Mura

Mura, one of the three types of waste in the Toyota Production System, translates to "unevenness" or "inconsistency" in English. It refers to the irregularity in the flow of work, causing fluctuations in capacity and production. Identifying and removing Mura is essential for creating a steady work pace and optimizing resources.

One of the main causes of Mura is multitasking. When team members are constantly switching between tasks, they often lose focus and efficiency, leading to unevenness in the workflow. This results in longer lead times, increased inventory, and higher costs.

Another cause of Mura is overproduction. Producing more than what is needed, whether it's goods or services, creates an imbalance in the system and results in unnecessary inventory. This not only ties up valuable resources but also increases the risk of defects and rework.

To handle Mura, one must first understand the root cause of the unevenness. This can be done through value stream mapping, a tool that visually represents the flow of work and helps identify areas of waste. By analyzing the current state of the process, one can identify the steps that are causing Mura and implement solutions to eliminate them.

One effective solution is to implement a pull system, also known as "kanban" in Japanese. This system ensures that work is only produced when it is needed, eliminating overproduction and promoting a steady flow of work.

Another solution is to implement standard work. By standardizing the work process, team members are able to work consistently and efficiently, resulting in less Mura. This also helps in identifying and addressing any abnormalities that may occur in the process.

Additionally, involving the team members in problem-solving and continuous improvement activities can lead to increased ownership and accountability, leading to a reduction in Mura.

Implementing a pull system, standard work and involving team members in problem-solving and continuous improvement activities can help organizations to create a steady flow of work and optimize resources.

It's important to note that Mura is not a problem that can be solved once and for all. It's a continuous effort and requires constant monitoring and improvement. Regularly conducting value stream mapping and Gemba walks, where one goes to the place where the work is done to observe and understand the process, can help in identifying and addressing Mura.

In conclusion, Mura is a key concept in lean management and must be addressed to ensure a steady work pace and optimize resources. By understanding the root cause of Mura and implementing solutions such as pull systems, standard work, and involving team members in problem-solving and continuous improvement activities, organizations can achieve the goal of smooth and well-organized workflow.

Standard WIP (SWIP)

The minimum amount of material or product that must be in the process at all times to ensure smooth operation.

Standard Work is a little underrated concept in Lean Manufacturing. It is not simply standardization or work standards.

Standard Work is composed of three elements: Takt time, Work sequence and Standard Work in Process (SWIP). Takt Time is a fundamental concept of Lean Manufacturing, and Work Sequence is relatively intuitive. SWIP, however, is a bit more complex.

SWIP refers to the minimum necessary in-process inventory (work in process or WIP) to maintain Standard Work. It is not more or less than what is needed. To calculate the appropriate quantity for SWIP, one must ask a number of questions.

While a rough estimate of SWIP can be obtained by using the equation SWIP = Sum of Cycle Times / Takt Time, it is still necessary to determine where exactly this SWIP should be applied. The following steps provide a guide for determining the appropriate quantity of SWIP:

what’S the team size?

Standard Work is the most efficient combination of manpower, material, and machine, and is based on takt, work sequence, and Standard Work in Process (SWIP). By definition, it should include manual work. If a process is fully automated, it is not considered Standard Work. Instead, it is likely an NC program.

To determine the appropriate team size, the sum of manual cycle time is divided by Takt Time. Therefore, one piece of SWIP per person is required. The equation for manual SWIP would than be:

SWIP(manual) = Team member x (1 piece = person)

When determining the amount of SWIP, there should be no rounding, unless there is less than a full person. In that case, round up to the nearest whole number.

process steps as automatic one-piece cycle machines

Standard Work assumes the use of multiple processes or machines, and separates human and machine tasks as much as possible.

When using an automatic cycle, the worker will only be responsible for loading and unloading, and will not be present during the actual cycle. The automatic cycle time must also be shorter than the Takt Time, ensuring that there is always at least one piece in the machine during each cycle.

This is known as SWIP (single piece auto), and is calculated as the number of single-piece automatic cycle machines multiplied by one piece per machine. There is no rounding necessary as it is not possible to have less than a full machine. However, this only applies to single-piece automatic cycles, and calculations for batch processes or cycles with longer lead times may differ.

process steps as a single-piece non-machine automatic cycle

The term "non-machine automatic cycle" refers to process steps such as the drying time for paint, curing time for epoxy, and cooling time for hot parts.

These process steps may not involve machines, but they do require a certain amount of time for completion. The ratio of this time to the Takt Time is known as the Single-Piece Non-Machine Automatic (SWIP) cycle.

It is important to note that this value should always be rounded up to the nearest whole number. In some cases, equipment like turn tables or FIFO racks may be used to manage the curing process, ensuring that a finished product is available for each takt, and a new one is added for curing.

Process steps with a batch automatic cycle

Batch processes refer to situations in which equipment is designed to unload and load multiple pieces at a time, rather than one piece at a time.

A common example is heat treatment processes where a vacuum must be maintained and the door cannot be opened for hours. In such cases, a batch of parts is removed and then another batch is loaded. The cycle time per piece may be less than the Takt Time, but the overall automatic Cycle Time is greater than the Takt Time.

The Single-Piece Non-Machine Automatic (SWIP) cycle in this case is calculated as (Automatic time / Takt Time) x 2. The reason for this is that in batch processes, which do not allow for the addition or removal of individual pieces during the Takt, an extra quantity of complete parts is required. This concept can be compared to the idea of a pulley and bucket system used to retrieve water from a well, where one bucket is at the bottom of the well, full of water and another bucket is at the top, full of water, and during Takt, you empty out the bucket one by one and fill it back up one by one.

It's worth noting that in formulas 2, 3 and 4, manual cycle time is not included in the calculation because rule #1 takes care of that. This is because every manual Cycle Time must be within Takt by definition of Standard Work and since the unload/load time will involve one piece, there is no need to add manual time back into the calculation (in most of the cases).

Muri

Muri, a Japanese term meaning "unreasonable, impossible, or overburdened," refers to the excessive demands placed on resources, such as equipment and operators, which can lead to wear and production downtime. This traditional Japanese concept is often associated with overburden, unreasonableness, and absurdity. However, it can be eliminated through the implementation of standard work practices.

INTRODUCTION

Lean management aims to optimize resources and eliminate wasteful activities in the production process. However, many lean practitioners often focus solely on identifying and eliminating the 7 wastes, known as Muda, neglecting the importance of the other two M's: Mura and Muri.

Identifying and addressing Mura (unevenness) is essential for creating a steady work pace, but it is equally important to identify and address Muri, which is the overburden of resources in the organization's work system. By identifying Muri, organizations can analyze and optimize the capacity of their workforce.

Let's dive deeper into understanding what Muri is and its significance.

What does Muri stand for?

As a lean expert, it's important to understand the concept of Muri, which is a Japanese term meaning "overburden or unreasonable." It is one of the three types of waste (Muda, Mura, Muri) and a key element in the Toyota Production System.

Muri occurs when demands placed on a team exceed their capacity, leading to stress and decreased productivity and efficiency. This can also result in extra working hours and occupational burnouts, negatively impacting team morale and the overall health of the work process.

To avoid this, it's important to be mindful of the workload and to strive for balance at the optimal capacity, where all parts of the system are able to deliver results without the need for extra work. It's also essential to understand the root causes of Muri in order to effectively address it.

What can Muri cause?

It's important to be aware that overburdening teams can occur without conscious intent. Setting unrealistic deadlines, for example, can lead team members to rush their work and result in poor quality and decreased customer satisfaction.

For instance, if a designer is asked to create twice the number of images they are capable of producing within a certain timeframe, it's likely that the final output will not be of the highest quality.

This analogy can be applied to an assembly line as well, where rushing the process can increase the likelihood of low-quality products being delivered to customers. There are various reasons that can contribute to creating Muri and it's important to identify and address them to maintain a smooth and efficient workflow.

Over-demanding

One of the most apparent causes of Muri is over-demanding, where higher management places excessive workloads on teams with the belief that more inputs will result in more outputs.

However, this often leads to a rising number of pending tasks and can cause chaos and burnouts among the team members. This over-demanding behavior is commonly seen in the contemporary business world, it is important for management to be aware of the consequences of overburdening the team, and to instead aim for a balance between inputs and outputs.

Lack of training

The lack of proper training can lead to inefficiencies and the prolonging of tasks. For example, if a team member is not properly trained for a specific task, they may take longer to complete it than necessary.

For instance, if an individual is trained as a copywriter but is assigned tasks of a designer, they may require twice as much time to produce high-quality images as compared to a regular designer who is properly trained for that role.

This highlights the importance of providing proper training and ensuring team members are equipped with the necessary skills to perform their roles effectively, which can help prevent Muri and optimize the workflow.

Lack of communication

Effective communication is crucial for the success of any team. To avoid overburdening, it is essential to establish clear communication channels and practices.

For example, if a meeting with team members is held and a decision is made to create 10 new landing pages for a website, it is important that all team members are informed and aware of the project, including the expected deadline.

Failure to do so, such as in the scenario where a designer is not informed until the last day before the deadline, can lead to overburdening and negative consequences of Muri due to miscommunication. Clear communication can prevent such situations and help teams work efficiently and effectively.

Lack of proper tools and equipment

When the necessary tools and resources are absent, the occurrence of Muri becomes evident and unavoidable. For example, if certain developers are given new computers while others are still using outdated equipment, the latter group will experience overburdening as they will require more time to complete their tasks.

Muri can be caused by various factors, it's important to keep in mind that managing and addressing all of them is crucial in order to maintain a stable and efficient workflow.

To effectively deal with Muri, it's important to identify and understand the root causes, and develop strategies to address them. This may include providing proper tools and resources, implementing clear communication channels, and providing adequate training to ensure that teams have the necessary skills to perform their roles effectively.

Different ways to deal with Muri

Lean management offers various techniques and strategies that can assist in minimizing the negative impact of overburdening or eliminating it altogether.

Map your team’s workflow

A useful starting point in identifying and addressing Muri is to map out your team's workflow. One tool that can aid in this process is a Kanban board, which visually displays the various stages of the workflow and allows for an understanding of your team's capacity and where value is added.

Next, implementing work-in-progress limits for each stage of the workflow can ensure that team members are not juggling multiple tasks at once, but are focusing on completing one task before moving on to the next. This helps to create an efficient pull system, which leads to better organization and prevents overburdening.

When dealing with multiple teams whose work is interdependent, it is important to also implement WIP limits on a global level. For example, if team A is responsible for developing new features for a software service and team B is responsible for deploying those features, but team A is delivering new features faster than team B can deploy them, team B will be constantly overburdened. To avoid this, team A must ensure that team B has the capacity to handle new features before starting work on them. This may mean that team A may have to wait, but it is better to have one team blocked than have the entire company impacted.

Standardize your process

Another approach to addressing Muri is through the implementation of standardization. By documenting all processes and providing thorough training to team members, you can ensure that everyone is equipped to complete their tasks in an efficient and effective manner. This promotes clear communication and helps to eliminate misunderstandings, which can contribute to overburden.

Practice Jidoka

Another Lean management technique that can be used to address Muri is Jidoka. This practice empowers team members to halt the work process if an issue arises, and requires the problem to be resolved before the process can continue. This helps to establish built-in quality standards and prevent the need for rework.

Furthermore, regularly conducting Gemba walks, which involve physically going to the work area to observe and understand what is happening, can also provide insight into where Muri is occurring and how it can be addressed.

In a nutshell

Many businesses unknowingly put excessive demands on their staff, known as Muri in Japanese. This can lead to decreased efficiency and wasted resources, impacting profitability. To address Muri, it is important to:

• Provide proper training and necessary tools and equipment to teams

• Establish clear communication channels and protocols

• Implement standard procedures within the organization

Standard Work Combination Sheet

In lean management, a standard work combination sheet is a document that displays the process steps for one or several employees. It is used to show the optimal combination of human and machine work. The sheet includes information on the timing values between different steps of the process, including manual work time, walk time, and machine processing time. The data recorded on the sheet is analyzed to identify any significant waste or delays in the process, and can be used to help determine the direction the company needs to take to address these issues. The sheet can also be used to evaluate the performance of individual employees, such as identifying if someone is overburdened with tasks or underutilized. Let’s go in a little bit detail in the following.

Standardized Work Combination Sheet

A Standardized Work Combination Sheet is a document that provides an overview of the interactions and timing between different parts of the work process. It displays how the various timing values such as manual work time, walk time, and machine processing time, combine and interact with each other. The sheet is designed to capture key data that is relevant to the understanding of the workflow and timing of the process.

What you should record

The data for each individual operator working on the floor is recorded in the Combination Sheet, and then analyzed using various forms of analysis. This sheet is useful for identifying any significant waste in delays between separate process steps, and can provide a clear indication of the direction the company needs to take to address these issues.

The most important points recorded in the sheet are the time required for human and machine movement, all based on the Takt Time. The sheet can help the company quantitatively evaluate an individual worker's performance and identify if they are overburdened by their current tasks.

Additionally, it can also reveal if a particular employee could be utilized more effectively. Often, companies may not realize that one of their workers is underutilized, spending less time performing actual work than expected. By properly recording and analyzing data using relevant tools to standardize the working environment, all the information will be easily accessible.

Eliminate waste

The Combination Sheet can help identify and eliminate waste in the production process by observing data recorded on the sheet, such as the time operators spend waiting for machines to complete tasks, waiting for input from other machines, or waiting for other operators to perform their tasks.

While some waiting may be necessary and an inherent part of the work process, it can be challenging to distinguish between necessary and unnecessary downtime. The Combination Sheet provides a comprehensive understanding of the current state of the production process and an objective view of each individual's involvement.

The data collected from the sheet is well-suited for graphical representation and can be easily analyzed using visualization tools. It may be incorporated into the sheet itself or handled by another department. The most crucial aspect is that the data is collected and organized correctly, as it can always be processed later.

How accurate should it be

The level of precision required for timing measurements can vary depending on the nature of your organizations processes. In some cases, it may not be necessary to record times down to the last second, such as when processes typically take over ten minutes. On the other hand, if the organization relies on many small and fast-paced processes, it may be necessary to use external devices to measure time as it would be difficult for a human operator to keep up.

It is essential to ensure that all data is measured consistently, as this is what establishes the validity of the data for later analysis. It is not advisable to round off one part of the data set while keeping another precise as it can lead to statistical deviations that are challenging to explain.

So what does it mean?

Employees may initially be uncertain about their new responsibilities related to completing the Combination Sheet, but taking the time to provide guidance and training can lead to significant improvements in the overall efficiency of the organization. Standard work can bring about significant changes in a company, but it is important to be patient and provide clear instructions during the initial implementation process. It can be a challenging transition, which is why it is essential to be well-versed in all the tools and techniques involved.
