Problem

Credit-risk decision models existed in three different decision-tree formats with no common representation for downstream use.

What was built

  • End-to-end design of a converter mapping three decision-tree model types onto a shared PMML notation.
  • Waterfall delivery: task breakdown, time estimates, delegation to juniors, and verification.
  • Work carried out on mock data structurally identical to production.

Outcome

Delivered on time; client very satisfied.
