The idea is to replace all the gained time with extra value-adding activities. However, when there is no need- or desire to add extra value as a replacement for the gained time, you will achieve the same value in less time!
Of course the trick would be to ‘cash’ this.
There are 2 possibilities:
1. Creating the same value in less time
✔ Efficiency gained. This can only be cashed if you do not need to pay for this time anymore.
2. Creating more value in the same time
✔ Effectiveness gained. The cost will stay the same, but you will have higher revenues from those costs.
