[2] The tool has seen use beyond Toyota, and is now used within Kaizen, lean manufacturing, lean construction and Six Sigma. The five whys were initially developed to understand why new product features or manufacturing techniques were needed, and was not developed for root cause analysis. In other companies, it appears in other forms.
The Toyota Way is a set of principles defining the organizational culture of Toyota Motor Corporation. [ 1 ] [ 2 ] 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 other organizations could adopt.

Six Sigma (6σ) is a set of techniques and tools for process improvement.It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1] [2]Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
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 [ 1 ] that organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers.
In these situations process map implies the use of process flow and the current understanding of the causal structure. Six Sigma practitioners use the term Business Process Architecture to describe the mapping of business processes as series of cross-functional flowcharts. Under this school of thought, each flowchart is of a certain level ...
Lean enterprise is a practice focused on value creation for the end customer with minimal waste and processes. [4] The term has historically been associated with lean manufacturing and Six Sigma (or Lean Six Sigma) due to lean principles being popularized by Toyota in the automobile manufacturing industry and subsequently the electronics and internet software industries.
Within Six Sigma, often complex analysis tools are used. However, it is acceptable to use basic tools if these are appropriate. Of the "validated" root causes, all or some can be. [clarification needed] List and prioritize potential causes of the problem; Prioritize the root causes (key process inputs) to pursue in the Improve step
Lean Six Sigma is a process improvement approach that uses a collaborative team effort to improve performance by systematically removing operational waste [1] and reducing process variation. It combines the many tools and techniques that form the "tool box" of Lean Management and Six Sigma to increase the velocity of value creation in business ...
