Optimizing 'Workshop Layouts' (b-w) is crucial for efficiency. Place 'Stockpiles' (p-s) for raw materials directly adjacent to the workshops that use them, and stockpiles for finished goods adjacent to the next workshop in the production chain or a 'Trade Depot' (b-D). For example, a 'Wood Stockpile' next to a 'Carpenter's Workshop' (b-w-c), and a 'Furniture Stockpile' next to a 'Trade Depot'. Minimize travel distance for your haulers.
