But today, my customers want 9 large multigrain loaves, 4 small ones, 3 really small soup bowl loaves, a dozen large white sours, 5 small and a couple of dozen bun loaves. On Friday they will want substantially different quantities. If I want to keep selling 95–100% of everything I bake, then I need accurate quantities, and I’d rather offload that essentially trivial calculation on a tool that gets it right every time. Five minutes after I arrive in the bakehouse, I have an accurate production sheet with the right quantities on it and I can concentrate on the far more important task of actually making the bread. I’ve spent maybe a couple of days, over the last year and a bit implementing the production planning software. Time well spent, I reckon.
