The Challenge: Two Incompatible Worlds
The bank was adding a new PI Lending application to an ecosystem where the legacy lending data model had been in place for years. The two systems spoke different languages: different structures, different logic, different representations of the same business reality.
Building a bridge between them — without breaking what already worked — required both deep technical analysis and significant stakeholder alignment. The relationship with the application’s Product Owner started under friction, adding pressure to an already demanding integration.
The Discovery: Bringing in IDS
IDS Consulting was engaged to lead the full integration: data model correlation, DWH impact assessment, specification writing, and delivery coordination.
The Solution: Technical Depth Meets Stakeholder Management
Like other complex integrations, this project required building a full understanding of the new system before production data was available. Analysis was driven by question-driven discovery and structured conversations — not observation of live behaviour.
- Data model correlation. The IDS team mapped the new PI Lending model against the legacy DWH architecture, identifying every point of divergence and designing the reconciliation logic.
- Specification-first delivery. Complete functional specifications were written without live data, validated through ongoing dialogue with the application team.
- Stakeholder alignment. Consistent professionalism and transparent communication turned a difficult working relationship into a productive one — eliminating the ping-pong dynamic that typically stalls integrations.
The Battle: Technical Ambiguity and Stakeholder Friction
Two forces worked against this project from the start: the inherent complexity of mapping incompatible data models, and the resistance of a key stakeholder who had not yet seen what IDS could deliver.
Results resolved both. By go-live, the technical integration was clean and the working relationship had been rebuilt on a foundation of trust.
The Results: Seamless Integration, Lasting Trust
- Near-zero post-launch incidents. The new PI Lending application went live with almost no integration-related issues.
- Data correctly correlated. Old and new models aligned with no gaps or duplication in the DWH.
- Timeline and scope fully delivered. The integration was completed as committed, within the agreed window.
- Stakeholder relationship transformed. From friction to transparent, trusted collaboration — a partnership built on delivery.
