Case Study #2
Analytical intelligence layer on top of operations
Built a flexible cost engine where business rules can change safely and quickly without interrupting day-to-day operations.
Context
Operating rules changed frequently by project and vendor conditions, while reporting needed stability and trust.
Problem
- Rule changes required slow report rework.
- Operational teams were disrupted every time logic changed.
- Decision timelines were blocked by technical release cycles.
Solution
Designed a policy-driven cost intelligence layer with rule catalog + versioning + validation before production activation.
- Separated ingestion, rule application, and visualization layers.
- Added rule lifecycle governance and rollback readiness.
- Enabled quick adaptation with controlled traceability.
How it worked day-to-day
- Rules proposed from observed exceptions.
- Replay test on historical data before approval.
- Controlled release with immediate dashboard effect.
Deliverables
- Rule dictionary and change log.
- Power BI semantic model with clear data contracts.
- Operational exception templates for team action.
Impact
- Faster change cycles from days to hours.
- Higher trust in numbers due to traceable rules.
- Lower disruption to operations teams.
Lessons
- Rule architecture is the real scalability lever.
- Interpretability matters as much as calculation accuracy.
- Fast change with governance beats rigid report stacks.
