Question

identity and discuss the main difference of classic and lean?

Answer 1

Lean manufacturing is an enterprise-wide strategy adopted by Toyota to achieve excellence by creating a culture, value and high-quality processes. The five major principles of lean manufacturing include pull, flow, value, perfection and value stream. The main perspectives addressed by these principles include customer, business process and waste elimination. Lean manufacturing is successfully implemented across various service businesses across the world to cut costs.
In classical manufacturing, products are manufactured based on a sales forecast and kept for ready purchase. Consider the case of ready-made shirts as an example of classical manufacturing. This is a push strategy. In lean manufacturing, production begins after the demand from the customers. Consider the case of stitching shirts from a tailor and ordering a food item at a restaurant as examples of lean.
In classical manufacturing, the system is improved with less or no regards to waste involved in the process while in lean manufacturing, the system is improved by improving the processes and eliminating the waste.
In classical manufacturing, a standardized procedure is followed in a routine manner by the employees indicating change is rare while in lean manufacturing, new procedures are introduced to improve the process on a regular basis indicating change is frequent in lean.
In classical manufacturing, change is brought by management through control while in lean manufacturing, every employee is empowered and takes part in the change process.
In classical manufacturing, people are trained to avoid mistakes adopting systems thinking to approach the problems. Normally, the problems are left unsolved in classical manufacturing until the operations flow in a smooth manner. In this classical approach, managers fail to view the opportunities available as a result of the existing problems. Lean manufacturing focuses on developing processes that are error-free making the people make mistakes difficult. Root cause analysis is used in lean-to identify the mistakes and convert the problems to opportunities.
