Professional Capability Objective
Build an anomaly-review workflow that identifies unusual expenses or transactions, explains why each item was flagged, and prioritizes cases for manual control review. The capstone is designed around a build-and-validate workflow so the learner produces working evidence, not only conceptual recommendations.
Industry Challenge
Control teams cannot manually inspect every transaction. Simple limits catch obvious issues but miss unusual patterns; pure ML can produce opaque false positives. A practical solution combines business rules, anomalies, and reviewer feedback.
Your analysis must consider:
- ▶Define policy-rule flags separately from learned anomalies.
- ▶Create peer groups by vendor, employee, category, or location.
- ▶Detect unusual amount, timing, frequency, or combination patterns.
- ▶Assign reason codes to every flagged case.
- ▶Use reviewer dispositions to analyze false positives.
- ▶Recommend which controls should remain deterministic and which benefit from statistical detection.
Why Employers Value This
Demonstrates your ability to:
- ▶Build interpretable anomaly detection for transactions.
- ▶Combine policy rules with unsupervised signals.
- ▶Prioritize cases and document reason codes.
- ▶Use reviewer feedback to improve controls.
- ▶Use reviewer dispositions to analyze false positives.
- ▶Recommend which controls should remain deterministic and which benefit from statistical detection.
Skills You'll Develop
Outlier detection
Detect unusual patterns systematically and distinguish useful alerts from noise and false positives.
Peer-group baselines
Create fair comparison groups and baselines so unusual behavior is assessed in the right context.
Rule + ML hybrid
Retrieve and rank the most relevant evidence so AI outputs are grounded in the right source material.
Risk scoring
Convert model signals into interpretable risk levels that support prioritization and intervention.
Case prioritization
Rank cases by risk, confidence, or impact so reviewers focus effort where it matters most.

Program Delivery & Engagement: 4 Stages
STAGE 1
Capstone Kick-off
Prepare transaction data and control rules.
→
STAGE 2
Build & Analysis
Build anomaly and risk-scoring logic.
→
STAGE 3
Practitioner Review
Create review queue and analyze reviewer outcomes.
→
STAGE 4
Final Submission & Demo
Present findings and control-improvement recommendations.
Completion standard: submit the working artifact, evaluation evidence, limitations, and a short final presentation. The certificate should reflect demonstrated capability rather than content consumption alone.
