Mining Intelligence Cost Model
End-to-end UX for a complex cost modelling tool
End-to-end UX design and project leadership for a sophisticated cost modelling tool used by mining operations teams to evaluate and forecast operational costs across complex multi-variable scenarios.
Critical cost insights locked in individual spreadsheets
Financial analysts and operations managers were building cost models in disconnected spreadsheets—a process that was time-consuming, error-prone, and impossible to collaborate on. Critical cost insights were locked in individual files rather than available organisation-wide.
From Excel-proficient analysts to C-suite
Financial analysts, operations managers, and C-suite at mining companies. Users ranged from highly Excel-proficient analysts to executive stakeholders who needed summary views without underlying complexity.

Progressive disclosure as the core design principle
01
Stakeholder Interviews
Conducted interviews across analyst, management, and executive levels to map the full cost modelling workflow and identify the biggest pain points.
02
Information Architecture
Designed the data model and IA to support both detailed analyst workflows and high-level executive summaries from the same underlying data.
03
Wireframes & Flows
Produced detailed wireframes for complex input forms, scenario comparison views, and visual cost breakdowns.
04
Data Visualisation Design
Designed chart and visualisation components that made multi-variable cost models scannable and actionable for non-analyst stakeholders.
05
Usability Testing
Tested with financial analysts and operations managers; iterated on input complexity and result presentation.
The hardest design problem was the same in every direction: analysts needed complexity that executives found paralyzing. The solution was not a compromise—it was progressive disclosure done properly.

Cross-functional visibility into cost data
Complex financial tools expose the limits of generalist UX. I spent significant time learning cost modelling concepts—not to design the model, but to design the interface that makes the model usable. Domain literacy is non-negotiable in enterprise UX.
