Let's Talk
Overview
Following the high-profile acquisition of Bank of the West (BOW), BMO needed to synchronize disparate, heterogeneous banking systems into a unified technical ecosystem to ensure brand and operational continuity.
Challenges
-
Incompatible Data Layers: Divergent tech stacks between the two organizations prevented data liquidity.
-
Operational Silos: Fragmented customer data hindered cross-selling and consolidated financial reporting.
-
Time Sensitivity: Integration needed to be completed rapidly to maintain customer trust during the transition.
Our Approach
-
Custom Adapter Layer: We engineered several specialized data adapters on AWS to bridge the gap between BOW’s legacy data structures and BMO’s core systems.
-
Interoperability Framework: Built a translation layer that allowed real-time communication between heterogeneous systems without a total re-platforming.
-
Data Orchestration: Harmonized disparate schemas into a single source of truth for the newly merged entity.
Results
-
Full Technical Integration achieved 20% ahead of the projected timeline.
-
45% Reduction in manual data reconciliation efforts.
-
Zero Service Interruptions for BOW or BMO customers during the transition.
Client Feedback
“Integrating an acquisition of this scale is a technical minefield. This team delivered the interoperability we needed without the risks typically associated with a merger.”
