How should you evaluate a switch?
Start with a representative task and the people who will do it. Evaluate search relevance, content ownership, freshness, access boundaries, and usable exports. Test the same inputs across your shortlist and record output quality, manual work, and current plan terms. Include migration work, access, and cancellation terms in the evaluation. A shared category does not make two products direct substitutes.
