Engagement and diagnosis

A supply-chain diagnosis begins with a bounded decision question, not a preferred remedy. Fix the segment, period, original promise and approval owner, then map order events from acceptance to proof of receipt, separating observed work from unexplained waiting. Every measure needs a numerator, denominator, exclusions and event definition. On-time arrival is not a perfect order: quantity, product, destination, condition and documentation also matter. A missing record remains unknown, so show conditional bounds rather than a false exact result. Once the gap is described, compare promise, inventory, capacity, carrier and logging hypotheses with tests in comparable segments. The module's recommendation is an executable next step proportionate to evidence strength, stating what might reverse it, its cost and the relevant decision right.
