01What they needed
Before changing a part, a team needs to see everything that change reaches: other parts, requirements, software and drawings. Their data arrives as spreadsheet exports, each team in its own format.
02What we built
- A graph engine that follows seven rules for how a change spreads, each with a set direction: upward, both ways or through to the target. It shows the path behind every result.
- Import that reads each team’s own spreadsheet format and keeps every column.
- Suggested links for parts left unconnected, which people confirm or reject, with undo, and a record of who confirmed each link and when.
- A data browser with search, editing that keeps every link consistent, depth and type filters, and sign in for the whole team.
