Why these three numbers
Almost every plant-floor decision routes through one of three questions: how much of our capacity are we actually using (OEE), what are our losses costing us (downtime cost), and what pace does demand require (takt time). These calculators answer all three in under a minute each, using the standard formulas — the same ones taught in lean and TPM programs and used in real continuous-improvement engagements.
Each calculator explains its formula, common mistakes, and how to act on the result, so the number you leave with is one you can defend in a production meeting.
