Internal Setup

Internal Setup, also known as Machine Changeover or Equipment Changeover, is a critical aspect of Lean Manufacturing. It refers to the process of switching a production machine from one product or production run to another. This process can be time-consuming and impact the overall efficiency of a manufacturing plant. For this reason, Lean experts have developed techniques to optimize the Internal Setup process and minimize downtime.

The Internal Setup process can be seen as a non-value-adding (NVA) activity. NVA activities are those that do not directly contribute to the production of a good or service. In the case of Internal Setup, it is necessary but does not add any value to the final product. The goal of Lean is to minimize NVA activities, and the Internal Setup process is no exception.

One of the key strategies for optimizing Internal Setup is to standardize the process. This can be achieved by creating detailed Standard Operating Procedures (SOPs) that outline each step of the setup process. SOPs should include clear instructions, diagrams, and photos to help guide employees through the process. The SOPs should also be reviewed and updated regularly to ensure they are up-to-date and accurate.

In addition to standardizing the process, Lean experts also focus on reducing the time required for Internal Setup. This can be achieved through a combination of reducing the number of steps required and streamlining the process. For example, the use of Quick Changeover fixtures or tools can reduce the time required to changeover a machine. Other strategies include minimizing the number of tools required, using visual aids to guide employees through the process, and using checklists to ensure all steps are completed.

Another important aspect of optimizing Internal Setup is employee engagement and involvement. Lean experts believe that employees who are involved in the process are more likely to take ownership of the process and be more committed to making it as efficient as possible. Encouraging employees to identify areas for improvement and participate in Kaizen events can also help drive continuous improvement.

Finally, it is important to monitor and evaluate the Internal Setup process on a regular basis. This can be done by tracking key performance indicators (KPIs) such as changeover time, number of changeovers, and machine downtime. The KPIs can be used to identify areas for improvement and measure the success of continuous improvement initiatives.

In a nutshell, Internal Setup is a critical aspect of Lean Manufacturing and Operational Excellence. To optimize the process and minimize downtime, Lean experts focus on standardizing the process, reducing the time required, involving employees, and monitoring and evaluating the process. By following these principles, manufacturers can achieve a more efficient and streamlined Internal Setup process, resulting in increased productivity, reduced waste, and improved bottom-line results.

NVA

Non-Value Adding (NVA) activities in the manufacturing industry can significantly impact the overall efficiency and profitability of a company. As an Operational Excellence/Lean Management Expert, I will explain how these activities can be reduced through a 3-step plan.

Step 1: Identification of NVA activities

The first step in reducing NVA activities is to identify them. This involves mapping out the entire manufacturing process, from raw materials to the delivery of finished products, and examining each step for activities that do not contribute value to the customer. These can range from administrative tasks to inventory management, and even some production activities that are not essential to the end product.

Step 2: Reduction of NVA activities

Once NVA activities have been identified, the next step is to reduce or eliminate them. This can be done through a combination of process optimization, technology implementation, and employee engagement. Process optimization involves re-designing the manufacturing process to remove NVA activities, while technology implementation involves incorporating automation systems to streamline operations. Employee engagement involves training and empowering employees to identify and eliminate NVA activities on their own.

Step 3: Continuous improvement

Reducing NVA activities is an ongoing process, and continuous improvement is key to maintaining efficiency and competitiveness. This requires regularly monitoring and assessing the manufacturing process to identify areas for improvement and taking corrective actions. Employee involvement is also critical in continuous improvement, as they often have the closest relationship with the process and can provide valuable insights into areas that need improvement.

In a nutshell, reducing NVA activities is an essential aspect of operational excellence and lean management. By following a 3-step plan of identification, reduction, and continuous improvement, manufacturers can significantly improve efficiency, reduce costs, and enhance the customer experience. The benefits of reducing NVA activities include increased productivity, reduced waste, improved quality, and increased competitiveness, making it a critical component of success in the manufacturing industry.

Flow Cell

Lean management is a production philosophy that seeks to streamline operations and eliminate waste, thereby improving efficiency and reducing costs. One of the key principles of lean management is the flow cell principle, which is all about optimizing the flow of materials, information, and processes within a manufacturing facility.

The flow cell principle is based on the idea that work should be performed in a continuous and uninterrupted flow, without any idle time or unnecessary delays. This principle is critical to achieving lean goals such as reducing lead times, improving quality, and increasing productivity. In order to implement the flow cell principle, a manufacturing facility must first identify and eliminate bottlenecks and constraints in its operations.

The flow cell principle can be applied to a variety of processes within a manufacturing facility, from raw material intake to finished product shipment. For example, in a manufacturing cell, raw materials are moved from one station to another in a continuous flow, without any stops or interruptions. Each station is designed to perform a specific task, and the flow of materials is carefully controlled to ensure that the entire process is as efficient as possible.

The flow cell principle is not just about physical movement of materials, however. It also involves the flow of information, as data must be shared in real-time across different departments and processes in order to optimize flow. A well-designed flow cell system should also include checks and balances to ensure that quality standards are met and that products are being produced to the required specifications.

Another key aspect of the flow cell principle is continuous improvement. Lean management emphasizes the importance of continuous improvement, and the flow cell principle is no exception. By constantly monitoring and analyzing the flow of materials, information, and processes, manufacturing facilities can identify areas for improvement and make the necessary changes to optimize their operations.

In conclusion, the flow cell principle is a critical component of lean management and is essential for achieving lean goals such as reducing lead times, improving quality, and increasing productivity. To fully realize the benefits of the flow cell principle, manufacturing facilities must implement it as part of a comprehensive lean management program, which includes continuous improvement, real-time data sharing, and strict quality control measures.

Just in Sequence - JIS

Just in Sequence (JIS) is a lean manufacturing principle that emphasizes the importance of delivering components to the production line at the exact moment they are needed. The goal of JIS is to minimize waste and improve efficiency by avoiding overproduction and reducing the amount of inventory in the production process.

In traditional manufacturing processes, components are often delivered to the production line well in advance of when they are needed, leading to large amounts of inventory and unnecessary waste. With JIS, components are delivered to the production line just in time, reducing the amount of inventory and freeing up valuable storage space.

JIS also helps to minimize the risk of stock obsolescence, as inventory is not kept for long periods of time. In addition, JIS reduces the risk of quality problems and defects, as components are delivered only when they are needed and there is less chance for them to become damaged or lost.

Implementing JIS in a manufacturing facility requires a high level of coordination and communication between suppliers, manufacturers, and logistics providers. A just-in-sequence system should be carefully planned and implemented to ensure that components are delivered exactly when they are needed, without any delays or interruptions.

One of the key components of a successful JIS system is a strong logistics network that can ensure timely and accurate delivery of components. This may involve using advanced technologies such as real-time tracking and data analysis to monitor the delivery of components and identify potential issues before they become problems.

Another critical aspect of JIS is the need for clear and accurate communication between suppliers and manufacturers. This can include the use of automated systems and data sharing to ensure that all parties are aware of the status of deliveries and can take the necessary actions to resolve any issues.

In a nutshell, the Just in Sequence (JIS) principle is an important component of lean manufacturing, as it helps to minimize waste, reduce inventory, and improve efficiency. To fully realize the benefits of JIS, manufacturers must implement it as part of a comprehensive lean manufacturing program that includes strong logistics, clear communication, and the use of advanced technologies. With the right approach, JIS can help manufacturers to achieve significant improvements in their operations, leading to increased competitiveness and profitability.

Line Balancing

Line balancing is a critical component of lean manufacturing and is a key tool for improving efficiency, reducing waste, and increasing productivity. The principle of line balancing is to ensure that every workstation on a production line is working at optimal capacity and that the overall line is balanced in terms of the workload and resources available.

We would like to provide an overview of the line balancing principle and its application in a manufacturing setting.

Line balancing is a process that involves analyzing the production line and determining the ideal workload for each workstation. This is done by breaking down the tasks involved in producing a product into individual steps, and then determining the time required to complete each step. Once this has been done, the steps are assigned to workstations, taking into account the workload and resources available.

The goal of line balancing is to ensure that each workstation is working at optimal capacity, with no workstation being overworked or underutilized. This results in a more efficient production line, with less waste and reduced lead times.

There are several benefits to line balancing in a manufacturing setting. Some of these benefits include:

1. Increased efficiency: Line balancing helps to ensure that each workstation is working at optimal capacity, which leads to increased efficiency and reduced waste.

2. Reduced lead times: By ensuring that each workstation is working efficiently, line balancing can help to reduce lead times and improve delivery times.

3. Improved quality: Line balancing helps to ensure that each workstation is working at the appropriate pace, which can help to improve quality and reduce the risk of defects.

4. Increased productivity: Line balancing helps to optimize the use of resources, which can lead to increased productivity and reduced costs.

5. Improved work environment: Line balancing helps to create a more balanced and less stressful work environment, which can improve employee morale and reduce turnover.

In order to implement line balancing in a manufacturing setting, it is important to follow a structured approach. This may include the following steps:

1. Define the production line: Define the production line and identify the workstations involved in the process.

2. Break down the process: Break down the process into individual steps and determine the time required to complete each step.

3. Assign tasks to workstations: Assign tasks to workstations based on the workload and resources available.

4. Monitor performance: Continuously monitor performance and make adjustments as necessary to ensure that the line is balanced and working at optimal capacity.

In a nutshell, line balancing is a key tool for improving efficiency and reducing waste in a manufacturing setting. By following a structured approach and continuously monitoring performance, manufacturers can ensure that their production lines are working at optimal capacity, leading to improved efficiency, reduced lead times, and increased productivity.

Overproduction

Overproduction is one of the seven kinds of wastes in the Lean Manufacturing methodology and refers to the production of goods in excess of what is immediately required by the customer. This type of waste can have a significant impact on the efficiency and profitability of a manufacturing operation, and as a Lean Management Expert, I would like to provide an overview of the negative effects of overproduction.

One of the main negative effects of overproduction is increased inventory costs. When a manufacturer produces more goods than are immediately required by the customer, the excess inventory takes up valuable space in the warehouse and incurs additional costs for storage and handling. This inventory also ties up capital that could be used elsewhere in the business, reducing the overall financial performance of the company.

Another negative effect of overproduction is increased lead time. When a manufacturer produces goods in excess of what is immediately required, the production line may become congested, leading to delays and increased lead time. This can negatively impact customer satisfaction and reduce the competitiveness of the manufacturer.

Overproduction can also lead to increased defects and decreased quality. When a manufacturer produces more goods than are immediately required, the pressure to maintain production speed and volume can lead to shortcuts being taken and decreased attention to detail. This can result in an increase in defects and a decrease in overall product quality, leading to customer complaints and reduced customer loyalty.

Finally, overproduction can contribute to a lack of flexibility and responsiveness. When a manufacturer produces more goods than are immediately required, they may not be able to respond quickly to changes in customer demand, leading to increased lead time and decreased customer satisfaction. This can also result in increased costs due to the need to adjust production processes and manage excess inventory.

In a nutshell, overproduction is a significant waste in the manufacturing process and can have a negative impact on efficiency, profitability, and customer satisfaction. By focusing on reducing overproduction and improving production processes, manufacturers can increase their competitiveness and improve their overall performance. We recommend that manufacturers continuously monitor their production processes and work to reduce overproduction and improve the overall efficiency of their operations

Change Over

Change overs refer to the process of switching a production line from producing one product to producing another. This process can have a significant impact on the efficiency and profitability of a manufacturing operation, and as a Lean Management Expert, I would like to provide an overview of change overs and how they can be improved with SMED (Single Minute Exchange of Dies) Workshops.

One of the main challenges with change overs is the time it takes to complete the process. In many cases, change overs can take several hours or even days, which can result in decreased production and increased costs. This can be a significant issue for manufacturers who need to be able to switch between products quickly and efficiently to meet customer demand.

Another challenge with change overs is the potential for mistakes and errors during the process. When a production line is being changed over, there is an increased risk of mistakes being made, such as incorrect parts being installed or procedures being skipped. This can result in decreased production quality, increased defects, and increased lead time.

In order to improve change overs, manufacturers can implement SMED Workshops. SMED Workshops are designed to streamline the change over process and reduce the time it takes to switch between products. This is achieved by identifying and eliminating non-value-added activities, such as time spent waiting for equipment to cool down or procedures that can be done in parallel. By eliminating these activities, SMED Workshops can significantly reduce the time it takes to complete change overs, allowing manufacturers to increase production efficiency and responsiveness.

SMED Workshops also help to reduce the potential for mistakes and errors during change overs by standardizing the process and reducing the number of activities that need to be performed. This can improve overall production quality, reduce defects, and increase customer satisfaction.

In nutshell, change overs can have a significant impact on the efficiency and profitability of a manufacturing operation. By implementing SMED Workshops, manufacturers can streamline the change over process, reduce the time it takes to switch between products, and improve production quality and customer satisfaction. As a Lean Management Expert, I recommend that manufacturers consider implementing SMED Workshops as a means of improving their overall production efficiency and competitiveness.

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
