How to evaluate software alternatives

An alternative is useful only when it improves a named constraint. Re-run the decision with changed inputs and include migration, retraining, integration, and exit work.

Change one condition

Name the budget, workflow, governance, scale, or operating constraint that makes the current option unsuitable.

Measure the switch

Test export fidelity, identity changes, downtime, retraining, parallel operation, and rollback before treating a lower subscription as savings.

Continue the decision
