Stand-up vs Sit-down Modular Cell Output Predictor

The output gain is modest. The lead time collapse is the real reason to convert.

All four percentage inputs are outcomes of a conversion rather than givens, and they depend on the product, the cell design and how the change is introduced — a badly run conversion delivers the fatigue increase without the handling reduction or the efficiency gain, and the model will happily compute that too. Standing work also has real occupational health consequences over a shift and is not appropriate for every operator or every jurisdiction; anti-fatigue matting, sit-stand options and rotation are part of a responsible conversion and are outside this calculation. Cells additionally need higher polyvalence to work at all, so pair this with a skill matrix assessment.
