One project rarely needs one engineer. Name the asset and see every discipline it typically requires — then hire one firm, several specialists into a shared workroom, or ask for a team to be assembled with a named lead.
Name the asset and the platform maps the engineering disciplines that asset typically requires. You can add or remove any of them — the mapping is a starting point derived from how these projects are actually staffed, not a rule.
Each discipline below carries a role on the project. Deselect anything you already have covered in-house — but be deliberate about it, because an unassigned discipline usually becomes an unresolved interface later.
