Benefits

The rolling planning is used when the required data for planning purposes that relate to the near future, can be determined by more accurate forecasting methods and therefore lead to better results. In addition to reducing the uncertainty in planning is therefore usually also the required time and manpower economical than with a total planning.

Disadvantages

Through strict adherence to rigid planning time points is omitted the dynamic consideration of important events. For this purpose, for production companies such as the input of a large contract or the failure of a bottleneck machine count. The problem is also that the regular planning change to acceptance problems among employees and associated operational and organizational difficulties may result. This in turn can lead to an increase in throughput times and inventories and a decreasing deadlines.

Therefore, the rolling planning comes in strict expression rarely used. Instead, it is combined with the concept of event- oriented planning.
