Backward termination
Backward scheduling is a term from project management and scheduling as part of it. Backward scheduling is the method of planning a project from its deadline. The logical counterpart to backward scheduling is forward scheduling .
Backward scheduling is also used in the context of production and material planning for the timely determination of the parts requirement (see requirements assessment ).
Project management
example
There is a date by which a sequence of activities should be completed or a product should be completed. With backward scheduling, it is now planned from the end with which logically preceding work steps it must begin in order to complete the project or product on time.
During planning, buffers can arise if the end date of the work package resulting from forward scheduling and the end date resulting from backward scheduling do not match. If this value is negative for a project that has already started, it is a negative buffer , ergo: the project (measured at the target end) is delayed. Then there are some general troubleshooting approaches:
- Postpone the project end date so that it fits again .
- Activities on the Critical Path will be streamlined so that it fits again . Example: by increasing the capacity of the service provider, if possible.
- Revising the project goal by removing part of the initially planned services.
Production Planning and Control
In the determination of requirements according to which: - with the aid of the cumulative quantities required quantities are pull principle - by a point of delivery (logistics) to the point of delivery lying in front according to the respective throughput time preferred, which is also called as a lead time , respectively.
