A rolling planning is a period oriented planning which helps to control in regular distances plans. So the rolling planning helps to actualise, to concrete and to revise the already done planning after clearly defined period of times.
Withal the planned period of time stays constant and is shifted regularly. The details are all the more exact when they’re in the near future. Projects in the distant future are first roughly planned and are then formulated more exact in the defined, regular plan revision.
Therefore the rolling planning supports the product management as well as the production planning.
