Select resources in the same activity and choose Group selected resources. Create a labour/equipment Crew or a Material assembly. Group totals summarize their members; they add no extra cost. Ungrouping keeps the lines.
Use Quantity basis on a resource:
- Entered quantity: hourly count or direct total.
- Activity duration × count × utilization: hourly usage.
- Per output unit: consumption factor × activity quantity, with optional waste.
- Fixed total: direct quantity stays unchanged.
- Lump sum: quantity stays 1.
Per-output rules do not convert units automatically. Do not add waste again if the factor already includes it. Grouping resources does not improve productivity automatically.

For a shared crew, open Resources & crews and Edit shared crew. Change worker/equipment composition and counts, select the intended linked uses, enter a reason, preview the impact and confirm crew updates. Each item keeps its own productivity. Customized uses require explicit selection; unrelated crews remain unchanged.
