TAMMO

Transparent Agile Maturity Model for Outsourcing

TAMMO is a lightweight, practical process maturity framework for software development outsourcing. It defines five maturity levels to standardize, measure, and improve transparency, collaboration, quality, and predictability between clients and vendors.

Transparency

Shared visibility of scope, progress, and outcomes so buyers and suppliers align on what is being built and when.

Collaboration

Structured agreements, iterative delivery, and demonstrable increments that keep both sides working from the same facts.

Quality & Verification

Demo environments, tests, and acceptance criteria so software is validated incrementally—not only at the end.

Predictability & Handover

Clear milestones, full delivery packages, and process metrics so delivery dates improve and projects can be reconstructed and maintained.
