Aeo Requirements

Use when evaluating build vs buy, comparing vendors, assessing a make or buy decision, analyzing total cost of ownership, evaluating SaaS against a custom build, or planning a vendor migration. Covers the decision framework, TCO models for both build and buy including upfront and ongoing costs, a vendor evaluation scorecard, feature-fit assessment, vendor due diligence, integration complexity and API evaluation, lock-in assessment, migration phases and a data migration checklist, and a decision document template. For the commercial decision; gathering the requirements themselves belongs to requirements-elicitation.
