The best approach for distributing work across multiple sewers (parallel stations) in Odoo is to create one Manufacturing Order per unit (1 MO = 1 finished unit) and run multiple MOs simultaneously. Here is the recommended setup:

1. Create a Work Center called Sewing with Capacity = number of sewers (e.g., 5). This lets Odoo schedule up to 5 concurrent units.

2. When you need to produce 5 units: create 5 separate MOs of qty=1 each, all referencing the same Work Center. Odoo will schedule them in parallel since the capacity allows it.

3. Alternatively, use the BoM split feature: create one MO for 5 units, then use Manufacturing > Split Production to split it into 5x1 unit MOs. Each sewer gets one MO.

Note: You are correct that Capacity does not distribute across workers - it only affects scheduling throughput. The Split Production method is the standard Odoo workaround for distributing individual units across workers/stations.
