The Challenge
A consumer finance company needed better default prediction without sacrificing regulatory transparency. We deployed an explainable ML credit risk model on Databricks — improving default prediction by 15% with full model interpretability. The organization faced mounting pressure from leadership to modernize. Existing systems and processes had reached their limits — manual workarounds consumed staff time, data quality was unreliable, and decision-makers lacked the visibility they needed.
The finance industry added specific complexity: regulatory requirements (SOX, PCI-DSS, GLBA, Basel III) demanded auditable processes and governance. Any technology change needed to maintain compliance continuity while delivering measurable improvement.
Previous attempts had stalled — either the technology was too complex for the internal team to maintain, the vendor didn't understand finance industry requirements, or the project scope expanded until timelines became unrealistic. This time, the sponsor demanded a phased approach with measurable results within one quarter.
Our Approach
We designed a phased approach optimized for speed-to-value and compliance continuity:
Use Case Definition (Weeks 1-2)
Defined AI use case with measurable success criteria and data requirements. Assessed training data quality.
Data & Feature Engineering (Weeks 2-5)
Built training data pipeline. Engineered features using domain expertise. Addressed class imbalance and data quality issues.
Model Development (Weeks 4-7)
Trained and evaluated models with rigorous cross-validation. Hyperparameter optimization. Compared architectures for the best accuracy/latency tradeoff.
Validation & Safety (Weeks 6-9)
Validated with domain experts on holdout data. Bias and fairness assessment. Edge case testing. Performance benchmarking against requirements.
Production Deployment (Weeks 8-12)
Deployed with MLOps pipeline. Model monitoring, drift detection, and automated retraining. Integrated into operational workflows.

Key Takeaways
If your organization is facing a similar challenge, here's what we learned:
Phased delivery de-risks large projects. By scoping the initial deployment for 8-12 week delivery, we proved value before the executive sponsor's next quarterly review. This maintained budget authority and organizational support for subsequent phases.
Finance domain expertise accelerates every phase. Understanding finance terminology, regulations, and workflows eliminated weeks of discovery that generalist consultants require. Our ai & automation team brought industry context from day one.
Change management is half the project. Technology implementations fail when users don't adopt. We embedded change management into every phase — from requirements workshops to training to post-go-live support. Adoption reached 80%+ within the first month.
Ongoing governance prevents regression. We established monthly review cadences, defined ownership for data quality and process adherence, and built dashboards that make issues visible before they become problems. The platform continues to deliver value because governance is sustained.
