Expert knowledge as an API
Calculation rules available to other systems, with a record of every run.
The challenge
Critical calculations were in legacy spreadsheets. They lacked controls to audit changes and versions. Maintenance depended on specific people.
The solution
We moved the rules to an API: an interface that other systems can query. We validate and version each rule. We record each run. We can expand the catalog without changing the core.
Current operation
- Every result is traced: what was calculated, with which data and which version
- The catalog grows without touching what is already validated
Origin
standards-based calculation · in production
How it works
Calculations based on technical standards were in spreadsheets. Auditing rules, controlling versions and reusing them across projects was difficult.
- Request with the data
- Validated, versioned rules
- A trace of every run
- Results for any system
Result
Every run is traced, and the calculation catalog grows without touching the core.
