A focused internal application replacing one heavily-used spreadsheet, with permissions and history.

Problem
ContextA critical spreadsheet has grown into a system of record: no validation, no permissions, no history, one owner.
User

Product idea
DirectionModel the data properly first, then rebuild only the workflows people actually use, with search and reporting on top.
02 / Architecture & workflow
