How to Assess Agile Team Maturity with ATMM: A Practical Guide

Agile Origins

Accelerating R&D and shortening the gap between product development and market launch has long been a challenge for product teams. Early agile practices emerged in 2000 when a group of passionate programmers in Oregon set two core goals: shorten delivery cycles to let the market validate product value, and continuously incorporate user feedback into new designs.

Agile Team Maturity Model

The article focuses on agile maturity assessment rather than basic agile definitions. Starting from AMM1.0 (Agile Maturity Model), the framework evolved to ATMM2.0 and now ATMM3.0, measuring team maturity across multiple dimensions and incorporating company‑specific delivery commitments. ATMM is rooted in agile but continuously refined to fit the organization’s operational shape.

Applying the Agile Team Maturity Assessment

Similar to a medical diagnosis, the assessment uses observation, listening, questioning, and case discussion to evaluate a team’s current agile practice. The results become private knowledge for the team, guiding improvement without comparing across teams.

In January 2022, the PMO led a maturity assessment for two stable agile teams, documenting the process and outcomes.

Assessment Process

Evaluator: PMO

Participants: All members of the agile team

Define assessment plan: select five dimensions—team roles & collaboration, product requirements, planning & monitoring, customer focus, and quality assurance.

Train the entire team on the assessment process and dimensions to ensure engagement.

Conduct a team‑wide assessment meeting, explain each dimension and scoring criteria, and facilitate 10‑minute discussions for each scenario before assigning scores.

Compile scores into a radar chart, review case examples, and agree on improvement actions with owners and deadlines.

Track the agreed actions over time and hold the team accountable for results.

Team Feedback

Teams reported that the assessment accurately reflected their operating state and was highly valuable. Brainstorming each dimension clarified expectations, revealed hidden issues (e.g., front‑end or testing resource needs), and produced concrete improvement measures with clear owners and timelines, strengthening cohesion and responsibility.

Key Takeaways

ATMM provides a comprehensive “health check” for agile teams, helping them identify gaps, set realistic goals, and implement targeted actions. The evaluator must understand each dimension, guide discussions effectively, and treat scores as diagnostic insights rather than mere numbers. Successful assessments lead to clearer awareness of problems, root causes, and concrete plans for resolution.
