LANGUAGE OF LEAN
Point Of Use
Point of Use (POU) is a key component of Lean initiatives aimed at reducing waste, increasing efficiency, and improving overall production processes.
Point of Use (POU) is a key component of Lean initiatives aimed at reducing waste, increasing efficiency, and improving overall production processes. It is a philosophy that focuses on delivering materials, tools, and equipment directly to the worker at the moment they need them. The goal of POU is to minimize unnecessary movement, handling, and storage of materials, which not only streamlines production but also reduces the risk of damage, loss, and obsolescence.
In traditional manufacturing processes, raw materials and supplies are often stored in central locations, such as inventory rooms, and are retrieved and moved to the production line as needed. This can result in excess inventory, increased lead times, and the need for multiple trips to retrieve materials. Additionally, workers may spend significant amounts of time searching for the tools or materials they need, which reduces productivity and increases the risk of mistakes.
Point of Use aims to eliminate these inefficiencies by bringing materials and supplies directly to the worker at the point of need. This reduces the need for workers to search for materials and increases the speed and accuracy of the production process. POU also reduces the amount of inventory that needs to be stored and managed, which helps to reduce the risk of damage, loss, and obsolescence.
There are several different approaches to implementing POU, each with its own set of benefits and challenges. One approach is to use kanban systems, which are visual signals that tell workers when it’s time to replenish materials or supplies. Another approach is to use automated systems, such as conveyors or robots, which move materials and supplies directly to the production line as needed.
Regardless of the approach used, POU requires careful planning and coordination between all departments involved in the production process. It also requires regular monitoring and adjustments to ensure that the system is working as intended. This can include tracking key performance indicators (KPIs) such as inventory levels, production lead times, and worker productivity.
One of the benefits of POU is that it helps to improve worker morale and job satisfaction. When workers have access to the materials and supplies they need exactly when they need them, they are able to focus on their work without worrying about finding the right tools or supplies. Additionally, POU helps to eliminate the frustration that workers may feel when they are unable to find the materials they need, which can lead to decreased job satisfaction and even burnout.
Another benefit of POU is that it helps to reduce the risk of mistakes and increase quality. When workers have everything they need at their fingertips, they are able to focus on their work without worrying about searching for materials or supplies. This reduces the risk of errors, which in turn helps to improve overall quality and reduce the need for rework.
In a nutshell, Point of Use is an important concept in Lean Manufacturing that aims to reduce waste, increase efficiency, and improve overall production processes. By bringing materials and supplies directly to the worker at the point of need, POU streamlines production, reduces the risk of damage, loss, and obsolescence, and improves worker morale and job satisfaction. To be successful, POU requires careful planning, coordination, and monitoring, as well as a focus on continuous improvement. By implementing POU and other Lean principles, manufacturers can reduce costs, increase efficiency, and improve overall production outcomes.

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.
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.
JIT
Just-in-Time (JIT) is a manufacturing and inventory control system in which raw materials, components, and finished products are delivered to the production line exactly when they are needed.
Just-in-Time (JIT) is a manufacturing and inventory control system in which raw materials, components, and finished products are delivered to the production line exactly when they are needed. The goal of JIT is to minimize inventory levels and reduce lead times, while maintaining high levels of production efficiency.
JIT is a pull-based system, which means that production is driven by customer demand rather than by a production schedule. This is achieved by using Kanban, a signaling system that alerts the supplier to send more materials or components when the inventory level of a specific item reaches a predetermined minimum level.
The origins of JIT can be traced back to the manufacturing practices of the Toyota Motor Company in the 1950s. It was developed by Taiichi Ohno, an engineer at Toyota, as a response to the inefficiencies he observed in the company's production processes. Ohno recognized that by reducing the amount of inventory and increasing the flow of materials, Toyota could improve its production efficiency and responsiveness to customer demand.
One of the key principles of JIT is the elimination of waste, or "muda" in Japanese. Ohno identified seven types of waste in manufacturing: overproduction, waiting, unnecessary motion, overprocessing, defects, excess inventory, and unused human potential. JIT aims to eliminate these forms of waste by creating a smooth and efficient flow of materials and products through the production process.
JIT also relies on the concept of "one piece flow", which is the production of one item at a time, rather than producing large batches of items. This allows for better control of the production process, as well as the ability to quickly identify and correct any problems that may arise.
Another important aspect of JIT is the use of visual management tools, such as Andon boards and Kanban boards. These tools allow for real-time monitoring of the production process, and can alert workers to potential problems before they become major issues.
JIT also requires a high level of collaboration and communication between suppliers, manufacturers, and customers. This is necessary to ensure that materials and components are delivered to the production line exactly when they are needed, and that finished products are delivered to customers in a timely manner.
JIT has a number of benefits for manufacturers. One of the most significant is that it can help to reduce inventory levels, which can free up valuable floor space, reduce storage costs, and minimize the risk of stockouts. JIT can also help to improve production efficiency by reducing lead times and minimizing downtime caused by waiting for materials or components.
JIT can also help to improve product quality by reducing defects, and increasing the ability to quickly identify and correct any problems that may arise in the production process.
JIT also helps companies to be more responsive to customer demand by reducing lead times and increasing the speed of delivery. This can help to improve customer satisfaction, and increase the chances of repeat business.
JIT also helps companies to be more flexible and adaptable to changes in customer demand. It allows companies to more easily shift production to different products or product lines, which can help to maintain profitability during periods of slow sales.
However, it's worth noting that JIT is not suitable for all industries and companies, it's best applied in companies where the production process is well-defined, the demand is stable and predictable, and the lead times are short. Implementing JIT can also be challenging and requires a significant investment of time and resources to establish an effective system.
Additionally, JIT requires a high level of coordination and communication with suppliers and customers, which can be difficult to achieve. This is particularly true for companies that have a large number of suppliers or customers, or those that operate in
Kaikaku
Kaikaku first creates the basics to later carry the Kaizen idea into manual production with CIP.
KAIKAKU, which means "radical change" or "revolution" in Japanese, is a key concept in Lean management and operational excellence. It refers to a transformative approach to process improvement that aims to achieve significant and lasting improvements in performance. KAIKAKU is different from other process improvement methods, such as Kaizen, which focus on incremental improvements, KAIKAKU is characterized by a bold, dramatic change in the way a process is performed.
One of the key features of KAIKAKU is that it is not just about improving the existing process, but also about rethinking and redesigning the process from scratch. This approach allows organizations to identify and eliminate sources of waste, inefficiencies, and bottlenecks that may have been present in the process for years. By starting with a blank slate, organizations can create a new process that is more efficient, effective, and sustainable.
KAIKAKU is often used in manufacturing and production processes, where significant improvements in performance can have a major impact on the bottom line. For example, a manufacturing facility might use KAIKAKU to redesign its production process, eliminating bottlenecks, reducing waste, and increasing capacity. This could result in faster turnaround times, higher quality products, and lower costs.
Another key feature of KAIKAKU is that it often involves the use of new technologies and automation. By adopting new technologies and automating processes, organizations can achieve significant improvements in performance. For example, a manufacturing facility might use KAIKAKU to introduce robots, automated inspection systems, or artificial intelligence to its production process. This could result in faster turnaround times, higher quality products, and lower costs.
KAIKAKU also involves the active participation of employees, especially those who are directly involved in the process. By involving employees in the process improvement process, organizations can tap into their expertise and knowledge, and create a sense of ownership and engagement. Employees can also bring valuable insights into the process and suggest new ideas for improvement.
KAIKAKU is also closely linked to the concept of "Just-in-Time" (JIT) manufacturing. JIT is a production strategy that aims to produce the right products at the right time, and in the right quantities, by minimizing waste and unnecessary inventory. By implementing KAIKAKU, organizations can achieve significant improvements in performance and implement JIT successfully.
In a nutshell, KAIKAKU is a powerful method for organizations that are committed to operational excellence and continuous improvement.

Mura
A traditional general Japanese term for unevenness. It is the waste of variation in the production process.
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 a given product, which must be in process at any time to ensure proper flow of the operation.
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).
