About lean-stack
From learning a lean practice to picking the software for it
lean-stack is an independent directory of lean tools. It puts the method, the math and the software in one place, so a team can learn a practice and compare the tools that support it without starting over on every vendor's site.
Why it exists
Three problems we kept running into
The problem
Vendor pages describe features, not practices.
What lean-stack does
Every tool sits under the lean practice it supports, next to a page that explains that practice.
The problem
Prices are scattered, hidden or out of date.
What lean-stack does
Each profile shows plans and prices in the same format, with the date they were checked.
The problem
Rankings are hard to trust when vendors can pay for them.
What lean-stack does
Lists are alphabetical, nobody pays for placement, and there are no scores until tools are tested hands-on.
What is here
7 areas of lean, one directory
The directory is organized the way lean teams work, from the shop floor to strategy and startups.

Who runs it
An independent team, with no vendor money in the lists
lean-stack is run by an independent team. The team has run kaizen events, A3s or value stream maps in real workplaces, and we built the site to make vendor information for lean practices easier to compare. We don't sell training or software. No tool has a lean-stack score yet, because we have not tested the tools hands-on. The rubric we will use is already public on the methodology page.
