A3 problem solving is a structured problem-solving and continuous-improvement approach, first employed at Toyota and typically used by lean manufacturing practitioners. [1] It provides a simple and strict procedure that guides problem solving by workers. The approach typically uses a single sheet of ISO A3-size paper, which is the source of its name. More contemporary versions include the Systems-oriented A3 (or S-A3) [1]
Ishikawa diagrams are causal diagrams created by Kaoru Ishikawa that show the potential causes of a specific event.
Lean manufacturing is a production method aimed primarily at reducing times within the production system as well as response times from suppliers and to customers. It is closely related to another concept called just-in-time manufacturing. Just-in-time manufacturing tries to match production to demand by only supplying goods which have been ordered and focuses on efficiency, productivity, and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle, flow, and throughput times by further eliminating activities which do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service.
Kaizen is a concept referring to business activities that continuously improve all functions and involve all employees from the CEO to the assembly line workers. Kaizen also applies to processes, such as purchasing and logistics, that cross organizational boundaries into the supply chain. It has been applied in healthcare, psychotherapy, life coaching, government, manufacturing, and banking.
The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices. The TPS is a management system that organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers. The system is a major precursor of the more generic "lean manufacturing". Taiichi Ohno and Eiji Toyoda, Japanese industrial engineers, developed the system between 1948 and 1975.
PDCA or plan–do–check–act is an iterative design and management method used in business for the control and continual improvement of processes and products. It is also known as the Shewhart cycle, or the control circle/cycle. Another version of this PDCA cycle is OPDCA. The added "O" stands for observation or as some versions say: "Observe the current condition." This emphasis on observation and current condition has currency with the literature on lean manufacturing and the Toyota Production System. The PDCA cycle, with Ishikawa's changes, can be traced back to S. Mizuno of the Tokyo Institute of Technology in 1959.
Operations management is concerned with designing and controlling the production of goods and services, ensuring that businesses are efficient in using resources to meet customer requirements.
Shigeo Shingo was a Japanese industrial engineer who was considered as the world’s leading expert on manufacturing practices and the Toyota Production System.
Muda is a Japanese word meaning "futility", "uselessness", or "wastefulness", and is a key concept in lean process thinking such as in the Toyota Production System (TPS), denoting one of three types of deviation from optimal allocation of resources. The other types are known by the Japanese terms mura ("unevenness") and muri ("overload"). Waste in this context refers to the wasting of time or resources rather than wasteful by-products and should not be confused with Waste reduction.
Genba is a Japanese term meaning "the actual place". Japanese detectives call the crime scene genba, and Japanese TV reporters may refer to themselves as reporting from genba. In business, genba refers to the place where value is created; in manufacturing, the genba is the factory floor. It can be any "site" such as a construction site, sales floor or where the service provider interacts directly with the customer.
Takt time, or simply takt, is a manufacturing term to describe the required product assembly duration that is needed to match the demand. Often confused with cycle time, takt time is a tool used to design work and it measures the average time interval between the start of production of one unit and the start of production of the next unit when items are produced sequentially. For calculations, it is the time to produce parts divided by the number of parts demanded in that time interval. The takt time is based on customer demand; if a process or a production line are unable to produce at takt time, either demand leveling, additional resources, or process re-engineering is needed to ensure on-time delivery.
Five whys is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "Why?" five times. The answer to the fifth why should reveal the root cause of the problem.
Value-stream mapping, also known as material- and information-flow mapping, is a lean-management method for analyzing the current state and designing a future state for the series of events that take a product or service from the beginning of the specific process until it reaches the customer. A value stream map is a visual tool that displays all critical steps in a specific process and easily quantifies the time and volume taken at each stage. Value stream maps show the flow of both materials and information as they progress through the process.
The Toyota Way is a set of principles defining the organizational culture of Toyota Motor Corporation. The company formalized the Toyota Way in 2001, after decades of academic research into the Toyota Production System and its implications for lean manufacturing as a methodology that could be adopted by other organizations. The two pillars of the Toyota Way are respect for people and continuous improvement. The philosophy was popularized by Jeffrey K. Liker in his 2004 book, The Toyota Way: 14 Management Principles from the World's Greatest Manufacturer. Subsequent research has explored the extent to which the Toyota Way can be applied in other contexts.
Norman Bodek was a teacher, consultant, author and publisher who published over 100 Japanese management books in English, including the works of Taiichi Ohno and Dr. Shigeo Shingo. He taught a course on "The Best of Japanese Management Practices" at Portland State University. Bodek created the Shingo Prize with Dr. Vern Beuhler at Utah State University. He was elected to Industry Week's Manufacturing Hall of Fame and founded Productivity Press. He was also the President of PCS Press. He died on December 9, 2020, at the age of 88.
Visual control is a business management technique employed in many places where information is communicated by using visual signals instead of texts or other written instructions. The design is deliberate in allowing quick recognition of the information being communicated, in order to increase efficiency and clarity. These signals can be of many forms, from different coloured clothing for different teams, to focusing measures upon the size of the problem and not the size of the activity, to kanban, obeya and heijunka boxes and many other diverse examples. In The Toyota Way, it is also known as mieruka.
A lean laboratory is one which is focused on processes, procedures, and infrastructure that deliver results in the most efficient way in terms of cost, speed, or both. Lean laboratory is a management and organization process derived from the concept of lean manufacturing and the Toyota Production System (TPS). The goal of a lean laboratory is to reduce resource usage and costs while improving productivity, staff morale, and laboratory-driven outcomes.
Lean IT is the extension of lean manufacturing and lean services principles to the development and management of information technology (IT) products and services. Its central concern, applied in the context of IT, is the elimination of waste, where waste is work that adds no value to a product or service.
Design for lean manufacturing is a process for applying lean concepts to the design phase of a system, such as a complex product or process. The term describes methods of design in lean manufacturing companies as part of the study of Japanese industry by the Massachusetts Institute of Technology. At the time of the study, the Japanese automakers were outperforming the American counterparts in speed, resources used in design, and design quality. Conventional mass-production design focuses primarily on product functions and manufacturing costs; however, design for lean manufacturing systematically widens the design equation to include all factors that will determine a product's success across its entire value stream and life-cycle. One goal is to reduce waste and maximize value, and other goals include improving the quality of the design and the reducing the time to achieve the final solution. The method has been used in architecture, healthcare, product development, processes design, information technology systems, and even to create lean business models. It relies on the definition and optimization of values coupled with the prevention of wastes before they enter the system. Design for lean manufacturing is system design.
Management System (Open Source) is a socio-technical system that leverages the cumulative knowledge of management practitioners and evidenced based research from the past 130 years. The system was developed by DoD components in partnership with industry experts and academic researchers and builds off of the US Department of Wars version 1.0 open source management system - Training Within Industry.
