This is a bizarre question. It never mentions that the financial savings should be reported at the annual level. However, that's a reasonable assumption to make. $7,500 * 12 months = $90, 000. A shoe manufacturing firm learned through a Lean Six Sigma project their boot soles could be made of a different material requiring two less steps in the process. Removal of these two steps yielded a monthly cost savings of $7,500. Therefore the reported financial savings for this LSS project were: A) $...
