There are a variety of tools being used in lean method, which can be broadly classified into three categories: 1) tools for process improvement, 2) tools for process management, and 3) tools for supporting lean implementation.
1) Process improvement tools: These tools are used to identify and eliminate waste in a process, and to improve the flow of value. Some common process improvement tools used in lean include value stream mapping, Kaizen events, 5S, and visual management.
2) Process management tools: These tools are used to help manage and control the process, and to ensure that it is running smoothly. Some common process management tools used in lean include process flow charts, process capability analysis, process FMEA, and SPC.
3) Tools for supporting lean implementation: These tools are used to help support the implementation of lean in an organization. Some common tools used in this category include value stream analysis, process improvement teams, and Lean accounting.
