The operating environment

Cross-functional permit processing in complex energy operations involves strict safety, environmental, and administrative compliance stages that previously relied on slow, manual document chains.

Field personnel and compliance officers suffered from zero status visibility, delayed approvals, and high risk of compliance errors when routing paper permits across multiple review teams.

03 · System

What I built
