This is what I'd imagine most of the people on here would fall into the trap of when the monthly 'I want to quit and work with my hands' post comes up. It's the cliche, I want to disrupt the industry before I even learn it.
My girlfriend works at a bakery and I showed her this post and asked her what she thought about it. None of the bakers need to write down anything or make spreadsheets on how to make a loaf of bread or any of the other products they make every day. This is like having to google 'how to write a for loop' even though you're a programmer.
Bakeries make the same things every day, there's very little change even though as a customer(me) it might look crazy. Knowing recipes and quantities and how to adjust them are the most basic requirements of the job.
Huge props to this guy for doing it though! I hate making negative posts shitting on someones venture. If this is what makes it more fun for him, then keep doing it, and get better.
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.
