It turned out to be more complex than anticipated and the costs often outweighed the benefits. This was the reason for most organisations to stop using MBT. Which is a shame, as experience proves that MBT can definitely contribute to productivity when used in the right situations. What are these situations?

- What are the risks that we want to remove or reduce?
The benefits of MBT can be observed at three levels:
- Reduction of time and cost involved
- Quality improvement
- Improved communications
