FLAGSHIP • PROFITABILITY & CONTROLS

From a low-margin report to a guardrailed profitability review

I designed the business logic for a workflow that identifies why margin is weak, blocks unsafe recommendations when evidence is incomplete, and creates review-ready outputs.

ChallengeLow-margin results showed the symptom but not always the true operational cause.

My roleDefined requirements, business rules, guardrails, root-cause categories, and test scenarios.

ResultCreated a more explainable and controlled review process with clearer next actions.
