“All we are doing is looking at the time line from the moment the customer gives us an order  to the point when we collect the cash. And we are reducing that time line by   removing the non – value added wastes” –  Taiichi Ohno, Toyota’s original “father” of Lean

Welcome to the home page of the INCOSE Lean Systems Engineering Working Group!

Please refer to our News page for the latest announcements (e.g. upcoming meetings, latest product releases)

We are dedicated to bringing the wisdom of Lean Thinking to the world of systems engineering. Our group is open to everyone who shares this interests, also non-INCOSE members. Please see the About Us page on how to join. We are currently the largest INCOSE working group with over 200 members.

The Working Group has developed a number of major products:
