What is an A3?

On a literal level, A3 refers to a ledger size piece of paper. But in the Lean Six Sigma world, it is a one-page project report.

This one-pager contains:

  • the problem
  • the analysis of the process
  • the identified root causes
  • potential solutions
  • action plan

…all on a large sheet of paper. The practice of using A3s forces project teams to focus their efforts while at the same time makes it easy for others to review their work.
