Six Sigma Green Belt Practice Questions study guide Test questions and Verified solutions 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. - answers 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.
