Yes, you can use this structured decision framework for team process changes. It applies to architecture decisions, tool selections, migrations, and process changes by forcing clear options and actionable steps across teams.

The best way to present trade-offs is by evaluating three distinct options labeled A, B, and C. Each option should explicitly list its pros and cons to guide teams toward a clear, unified recommendation.

This framework handles implementation planning by generating an aligned Definition of Done and an Implementation Plan immediately following the single recommendation, ensuring the chosen option translates into actionable execution steps.
