Understadning Lean Methodology


What does Lean Entail

Lean manufacturing, also known as lean methodology, is a business strategy that focuses on maximising value while minimising waste. It originated in the manufacturing industry but has since spread to a variety of industries such as healthcare, finance, and service. The goal of Lean methodology is to identify and eliminate non-value-added activities in a process while continuously improving it to increase efficiency and effectiveness.

Lean methodology is based on five fundamental principles:

  • Value: A strong emphasis is placed on identifying the value that a process or product provides to the customer.
  • Value Stream: The value stream is the set of activities required to create a product or service. The goal of lean methodology is to find and eliminate non-value-added activities in the value stream.
  • Flow: Lean methodology focuses on creating a smooth, continuous flow of work through the value stream.
  • Pull: The goal of Lean methodology is to create a pull system in which products or services are produced only when they are required, rather than in anticipation of demand.
  • Continuous Improvement: The Lean methodology is based on the concept of continuous improvement, also known as Kaizen. This entails looking for ways to improve the process and eliminate waste on a regular basis.
