Lean Manufacturing is driven by the pull of the customer's order, where production is ideally only initiated when orders are received from customers. The concept of Just-In-Time (JIT), is fundamental to Lean Manufacturing, and will potetially help to reduce a lot of waste.urthermore, Lean Manufacturing aims at supplying these goods and services with minimum waste, where waste in production is reduced through continuous improvements of the production processes.
Essentially, lean is centered on making obvious what adds value by reducing everything else. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System (TPS) (hence the term Toyotism is also prevalent) and identified as lean only in the 1990s.oyota's view is that the main method of lean is not the tools, but the reduction of three types of waste: muda (non-value-adding work), muri (overburden), and mura (unevenness), to expose problems systematically and to use the tools where the ideal cannot be achieved.
