Product: Advanced Modeling Platform (AMP)
AMP: Redesigning a Financial Forecasting Tool for Efficiency and Trust
THE CHALLENGE
GE Power’s financial modeling software, used to forecast billing, outages, and parts flow for $35B in turbine service contracts, was outdated and inefficient. Modelers spent hours creating workarounds, pulling data from Excel, backend systems, and contracts just to update or build a model. These inefficiencies slowed operations, introduced errors, and reduced trust in the tool.
Our challenge: modernize the platform to streamline modeling, reduce errors, and restore confidence in the system.
THE BUSINESS GOALS
We partnered with business and engineering teams to:
Cut operations and maintenance costs through better modeling and scenario planning
Improve modeler efficiency by 25% (reduce margin review cycles by two weeks)
Minimize modeling errors and manual workarounds
THE DESIGN APPROACH
To make the platform intuitive and powerful, we grounded our design in these principles:
Clarity: Use meaningful labels and logical structure aligned with modelers’ mental models
Efficiency: Reduce steps to complete a margin review and centralize external data within the app
Discoverability: Make key data visible, discoverable, and actionable
Consistency: Use Material Design and Angular Material for a scalable design system
MY ROLE
As the Lead Product Designer, I guided the end-to-end UX process from research to validation.
Understand
Conducted stakeholder discovery, user interviews, and observation sessions
Mapped workflows to uncover pain points and inefficiencies
Analyze
Identified key opportunity areas and defined future-state user flows
Design
Led design studios and critiques with cross-functional teams
Created prototypes, design system components, and high-fidelity interfaces
Validate
Designed and facilitated user testing scenarios
Synthesized feedback into actionable design refinements
THE UX PROCESS
Each 2 to 4 week UX sprint followed a consistent rhythm:
Define business and user requirements
Observe users remotely to understand real workflows
Synthesize findings into insights and opportunities
Ideate and prototype feasible solutions
Validate concepts through user testing
Iterate or hand off refined designs for development
This structured, iterative process helped our team move from assumptions to evidence-backed design decisions, ultimately improving modeler productivity and reducing friction across GE Power’s forecasting operations.
“With our current tools, it is nearly impossible to deliver a well thought out financial model in just a few days.”
