Enter each cost either as a direct annual dollar amount, or as units per year × cost per unit. Reduction % is how much of that line the project removes (0 if none).
3. Improvement project
When NOT to use this
- It does not measure defects. The reduction percentages are your assumptions, not predictions.
- No "hidden factory" multiplier is applied. Enter hidden costs as your own line items only if you can defend them.
- Lost customers and brand damage are not estimated unless you enter them as a line.
- Savings are assumed flat, arriving at the end of each year. There is no ramp-up period.
- Illustrative business-case tool only, not for regulated cost reporting.
