The document describes an Agile Testing Maturity Model (ATMM) that can be used to assess the maturity level of testing practices within agile teams. It outlines four levels of testing maturity (L1-L4) related to team behavioral models, with examples of how different testing categories may mature at different rates across the levels. The model is intended to help identify a team's current maturity, recognize issues, and plan next steps to continuously improve testing practices.
