PDF | Many people don't understand the DNA of the Toyota Production System and the core values of the Toyota Way. I have seen many who think It took him seven books to explain and decode the TPS. It is a Thinking. elements of a manufacturing system (people, machines, tooling, and products) and In James Womack wrote a book called "The Machine That Changed. Chapter 3 - The Heart of the Toyota Production System: Eliminating Waste. Ch apter . I hope this book will give you an understanding of what has made Toyota .

If a particular process experiences difficulties in keeping the pace, the processes upstream and downstream are usually unaware of it and keep working to the original schedule. Variances between scheduled activity and actual execution necessitate large inventories or multiple inventory stocks throughout the process. A downstream process simply takes what it needs, the shortage is visualized, and the upstream process replaces it.

Kanban systems are generally considered advantageous when a process produces multiple parts in small amounts. Process mapping Process mapping is one of the oldest but a very valuable technique for streamlining workflow. Process mapping in general refers to activities involved in defining exactly what a business entity does, who is responsible, to what standard a process should be completed and how the success of a business process can be assessed.

After successful process mapping, there should be no uncertainty regarding the process. A rather modern approach focusing on the value stream of procedures is known as value stream mapping VSM. Value stream mapping Value stream mapping VSM is a process for planning and linking lean initiatives through systematic data acquisition and analysis that often gives additional insights.

The various icons have specific meanings; knowledge of these symbols as well as knowledge of the TPS are necessary to interpret a VSM and to use it well.

Like geographic maps, value stream maps come in various forms and levels of detail, depending on the purpose and the processes analysed. Open image in new window Fig. Each vertical line represents the story of a person or workstation while the horizontal line represents the story of the product in creation.

Thus, processes and operations are easily separated.

VSM is commonly used in lean environments to identify opportunities for improvement in lead-times. Although VSM is often associated with manufacturing, it is also applied in logistics, supply chains, and service-related industries including health care, software and product development [ 5 , 6 , 7 ].

They are unnecessary actions and hence should be eliminated completely. Examples are waiting times, stacking intermediate products or double handling. Necessary but non-value-adding activities may be wasteful but are necessary or mandatory under current e.

Examples include walking to pick up parts and unpacking deliveries. In order to eliminate these types of operations, it is often necessary to implement major changes in the clinical setup, e.

Value-adding activities involve the useful and further conversion or processing of raw materials to semi-finished and ultimately to finished products.

Results In an interdisciplinary approach including referrers physicians, nurses and other staff on referring wards, e. As the ultimate lean target is the total elimination of waste waste, or muda, is anything that adds cost or time without adding value , the process was analysed by pursuing a waste-driven approach, i.

The seven wastes of the TPS are listed below and described from both the procurement and medical perspective: 1. Not much later WWII started. Post-WWII, rampant inflation meant getting paid by customers was very difficult. Cash-flow problems lead to pay cuts. When situation worsened, workers were asked to retire voluntarily. The resultant work stoppages and public demonstrations by workers led to resignation of Kichiro. Eiji Toyoda took over as president.

Eijis main contribution leadership towards development of the TPS. Eiji hired Taiichi Ohno as the plant manager and asked him to improve Toyotas manufacturing process so that it equals the productivity of Ford. Deming told the Japanese industry about meeting and exceeding customer satisfaction.

Also broadened the definition of customer to include both internal as well as external customers. Otherwise JIT wont work.

Ford vs. Toyota Fords mass production system was designed to make huge quantities of limited number of models. Toyota needed a system to make low volumes of different models using the same assembly line.

Ford had cash and a large market. Toyota needed to turn cash around quickly.

Toyota didnt have the resources for huge volumes of inventory and economies of scale afforded by Fords mass production system. The mass production system was focused on short-term costs. Make bigger machines and through economies of scale drive down cost. Automate to replace people if it can be justified in terms of cost.

Then the business world got the quality religion from Deming, Juran, Ishikawa and other quality gurus. Combining these Toyota developed the TPS which focused on speed in the supply chain. Shortening lead time by eliminating waste in each step of a process leads to best quality and lowest cost, while improving safety and morale.

Toyota system demonstrates that focusing on quality actually reduced cost more than focusing only on cost. Section II The Right processes will produce the right results Principle 2: Create continuous process flow to bring problem to the surface.

Principle 4: Level out the workload heijunka. Principle 5: Build the culture of stopping to fix problems to get quality right the first time. Principle 6: Standardize tasks are the foundation for continuous improvement and employee empowerment. Principle 7: Use visual control so no problems are hidden.

Principle 8: Use only reliable, thoroughly tested technology that serves your people and processes. Section III Add value to the organization by developing your people and partners Principle 9: Grow leaders who thoroughly understand the work, live the philosophy, and teach it to others.

Principle Develop exceptional people and teams who follow your companys philosophy. Principle Respect your extended network of partners and suppliers by challenging them and helping them improve.

Section IV Continuously solving root problem drives organizational learning Principle Go and see for yourself to thoroughly understand the situation genchi genbutsu. Principle Make decisions slowly by consensus, thoroughly considering all options, implement decisions rapidly.

Principle Become a learning organization through relentless reflection hensei and continuous improvement kaizen. TPS is much more than that! This defines value.

Through the customers eyes, we can then observe the process and separate the value-added steps from the non-value added steps.

This can be applied to any process manufacturing, or a service. Waiting: Workers having to stand around waiting for the next processing step, tool, part etc. Or no work because of stock-outs, lot processing delays, equipment downtime, and capacity bottlenecks.

Unnecessary transport: Carrying WIP long distances, creating inefficient transport, or moving parts in and out of storage facility. Over-processing or incorrect processing: Taking unneeded steps to process the parts. Inefficient processing due to poor tools and product design, causing unnecessary motion and producing defects. Waste generated when providing higher-quality products than is necessary.

Excess inventory: Excess raw material, WIP or finished goods causing longer lead times, obsolescence, damaged goods. Extra inventory hides problems such as production imbalances, late deliveries from suppliers, defects, equipment downtime, and long set-ups. Unnecessary movements: Any wasted motion employees have to perform during the course of their work, such as looking for, reaching for, or stacking parts, tools etc.

Walking is a waste.

Defects: Production of defective parts or correction. Repair or rework, scrap, replacement production, and inspection mean wasteful handling, time and efforts. Unused employee creativity: Losing ideas, skills, improvements, and learning opportunities by not engaging or listening to your employees.The world around us looks modern, but only because we don't see the tradition beneath the surface. Some of the approaches discussed by Ohno including reducing batch sizes and reducing inventory are shown in practise in the novel The Goal , which might be a more appetising way to consuming some of these ideas than Ohno's book.

This approach of learning and doing yourself became integral part of TPS genchi genbutsu.

Creates flexibility If shorter lead times, more flexibility to respond and make what customer really wants. That alone would be quite an notable feat. TPS Traditional approach focuses on identifying local efficiencies. Success in manufacturing was felt to demonstrate Japanese ingenuity and creativity and therefore proof that they are not inferior to Europeans pp Process mapping Process mapping is one of the oldest but a very valuable technique for streamlining workflow. Sometimes it can be performed with computer assistance, e.

The mass production system was focused on short-term costs.
