Field notes
The index organizes tools by work area and gives concrete input/output descriptions. For concrete, it lists dimensions, an allowance rate, and truck capacity as inputs for estimating volume, order quantity, and vehicle count. Manufacturing entries include yield, takt time, OEE, and Cp/Cpk; the homepage says formulas and rationale accompany the calculators, though their individual pages are not shown in this extract.
