  • Ability to read and critically assess extensions and ISV code, not just functional configuration.
  • Integration architecture depth: Dataverse, dual-write, Logic Apps or equivalent middleware, and batch and performance diagnostics at high transaction volumes.
  • Evidence of holding design authority across multiple vendors simultaneously, including at least one large SI, and the ability to describe how they made decisions stick without line authority over the vendors.
