Lean and ISO 9001

Answer:

Although there is a lot of overlapping between ISO 9001 and Lean in terms of purpose and principles, they are different in many ways.

Lean is the set of management practices based on the Toyota Production System (TPS). The Toyota Production System, a.k.a. Lean is defined as having three primary pillars:
1. Just-in-Time (improving flow)
2. Quality at the source
3. Waste reduction

On the other hand, ISO 9001 is a management system that is focused on quality of products and services and customer satisfaction. ISO 9001 represents a set f requirements that organization needs to meet in order to establish quality management system, while Lean represents set of tools and practices that should enable company to reduce waste, ensure quality and improving processes. If you ask a consultant to implement ISO 9 001 you will get one one type of the system, and if you ask him to implement Lean you will get another type of the system. They can be implemented at once to create one system and they are good at supplementing each other but they are not the same.
