Lean and JIT Manufacturing
K.krishna Veni
Is there any difference between Lean and JIT Production?

Lean is not JIT
Eric Schmitz, SIG Leader
JIT is only one of the tools of Lean. Lean itself a total business strategy! So you can have a lean business strategy, operational plan and so on that does not have JIT.

Yes there is a difference even more this are two different things! Lean is a strategy based upon:
1) Elimination of all waste (8points)
2) Continuous improvement
3) Customer service and last but not least respect for people.
JIT is like it says: just in time => is perfectly possible with a lot of stock and unnecessary process steps.
In my opinion JIT is not one of the tools of lean, for me it's also a strategy you choose. But it can help you to make the company more "lean".

Lean is a way to think while JIT is a tool to do this one

Three Philosophies of Lean
I always teach my classes that in order for a company to be lean they need to adopt three philosophies:
- JIT which is to have only the inventory that is needed at the place it is needed,
- TQM, concentrating on continuous improvement.
- Theory of Constraints.
There is also the need to an understanding that this extends through the supply chain as well your own company.

JIT Part of TQM
Rajeev Kumar, Member
The four guiding principles of TQM are:
- delight the customer
- management by fact
- people based management
- continuous improvement
JIT is a one of the management methods of TQM to achieve the four principles of TQM.
Toc is all about finding the constraint in the system and exploit it to full extent.

JIT and Lean
Sabari, Member
Lean is defined as producing the right parts, in the right place at the right time. JIT is one of the ways of achieving lean. JIT always focuses on implementation of 5S (Sort, Segregate, Shine, Standardize, Sustain) and Kaizen (Continuous Improvement).

Lean and JIT are Exhaustive Strategies
vijay kumar, Member
Lean and JIT are both exhaustive strategy approaches. Lean focuses on elimination of waste and improving organizational efficiency.
JIT focuses on improving efficiency by adding an additional layer for every activity carried in production, but waste gets accumulated in the process of delivering the output. It improves the output however cost of output is higher. Kindly give inputs on my observations.
