Driving Core Banking Transformation at First Hawaiian Bank

Driving Core Banking Transformation at First Hawaiian Bank

Overview

When First Hawaiian Bank sought to modernize its core banking operations, the scale and complexity of the initiative required a dedicated delivery partner. To bridge the gap between strategy and execution, the organization engaged DataHouse to drive the project across four critical pillars: Project Management, Business Analysis, Quality Assurance, and Training.

Objective

Strengthen program and project management execution.

Improve requirements clarity and acceptance readiness.

Establish robust QA and testing processes.

Support training and knowledge transfer for smooth adoption.

About the Organization

First Hawaiian Bank is a premier Hawaii-based regional bank requiring structured delivery support, cross-functional coordination, and quality assurance to execute a complex core migration initiative.

Challenge

Problem Statement

First Hawaiian Bank was undergoing a complex core migration with coordination gaps across multiple teams and systems, limited planning visibility, unclear requirements, weak QA coverage, and insufficient training readiness, all of which created significant delivery and adoption risk. 

Impact

Without a coordinated delivery framework, the bank risked scope creep, missed milestones, and a disjointed go-live that could undermine operations and stakeholder confidence. Fragmented testing and unclear requirements threatened to surface critical defects late in the cycle, increasing cost, timeline risk, and the potential for business disruption during a high-stakes system transition. 

Solution

Proposed Solution

DataHouse partnered with First Hawaiian Bank to provide comprehensive delivery support across the full lifecycle of the core migration initiative.  We embedded delivery expertise directly into First Hawaiian Bank’s project teams, providing structured consulting and program execution support across planning, execution, quality, and readiness.  The engagement delivered the following capabilities: 

Key Features

Structured Project Governance: Implemented standardized planning, scheduling, and stakeholder coordination to ensure accountability.

Precision Business Analysis: Conducted stakeholder analysis and documentation to transform business needs into clear, actionable requirements and UAT (User Acceptance Testing) criteria.

End-to-End Quality Assurance: Established a robust QA framework, including test planning, defect tracking, and automation design to ensure system integrity.

Change Management & Training: Developed comprehensive training materials and adoption strategies to prepare the workforce for the new system.

First Hawaiian Bank has a long-standing relationship with DataHouse, and we appreciate the partnership that the team at DataHouse provided as we look to implement the VizPlatform (formerly 'LumiSight') application. The implementation and customization of the VizPlatform app has gone smoothly for us, and we appreciate DataHouse's partnership. We have experienced very few challenges, and the team has been very responsive to our requests.
