Lean Manufacturing

14 key points of Deming for quality improvement: Create stable goals for improving products and services, aiming to increase competitiveness, maintain business, and provide employment opportunities. Adopting a new concept we are in the era of new economics. Western management must recognize tasks, learn its responsibilities, and demonstrate leadership in change. Stop dependency checking to achieve quality. The need to eliminate large scale inspections is achieved by first establishing the quality of the product.

Lean manufacturing: - identifying and eliminating waste is the central theme of a wasteful manufacturing system. Lean production is a dynamic and continuous improvement process that depends on the understanding and participation of all employees. To be successful, all employees need to be trained to identify and eliminate waste in the workplace. Waste exists at all levels of all work and organization. Production exceeds demand, production speed exceeds demand. Overproduction refers to the manufacture of goods before they are actually needed. Overproduction hinders the smooth flow of materials and actually reduces quality and productivity, which is costly for the manufacturing plant. Because each product is manufactured as necessary, Toyota production method is also called "JIT".

The mapping between lean manufacturing and lean software development originally began with the book "Lean Software Development: Agile Toolkit" by Lean and Tom Poppendieck in 2003. In this book, Poppendiecks explains how to effectively apply lean manufacturing principles to software development. Both manufacturing and software development follow repeatable procedures and require accurate quality standards. They also rely on teamwork to achieve work. Therefore, seven lean production principles can be applied and used for software development.
