A3 thinking: A3 learning: A3 process: A3 report: K-Brief
How can a simple piece of paper be all of these things? (A3 is the international equivalent to US 11.5” x 17”)
The secret is in how you use the paper to build consensus for action — remember Liker’s principle 13 – Make decisions slowly by consensus, thoroughly considering all options; implement decisions rapidly (The Toyota Way) — in Toyota and a growing number of other organisations, including some in design and construction, the A3 process – yes it is a process – is key to making that happen.

In Ready, Set, Dominate Kennedy et al refer to A3s as K-briefs (short for knowledge briefs). The book is in the form of a novel and includes good examples of the evolution and power of the A3 process – the A3 report or K-brief is the output from the process. The way it is produced is far more important than the output.
