Evaluate AI Workflow Product Metrics

You are evaluating an AI workflow suggestion feature in a cloud product. The feature recommends workflow actions or automations to users. Part A: After launch, many users click the suggestions, but relatively few complete the suggested workflow. Feedback from users who interacted with the feature is generally positive. How would you explain the high-click, low-completion pattern? What metrics, cuts, and analyses would you run? Part B: Power users are very active with the feature, but ordinary users rarely use it. How would you diagnose whether this is healthy early adoption, poor product-market fit for casual users, discoverability issues, or measurement bias? Part C: A product manager argues that a click itself means the feature has value. How would you respond, and how would you test whether clicks create real incremental value? Part D: Later, the underlying AI agent becomes stronger. Many tasks can now be completed automatically, so human message volume declines. At the same time, API usage and workflow actions increase. How would you interpret these apparently conflicting metrics? Part E: If API usage growth is mostly driven by a small number of large customers, how would that change your readout? Part F: Many workflow actions are stuck in `review_pending`. How would you measure whether this is a trust problem, a capacity problem, a UX problem, or a normal approval-process artifact?
