Planning Horizon in Project Management – Definition and Meaning
The planning horizon refers to the specific future period for which a project plan is developed in detail and remains valid. It is used to clearly define the time frame of planning, which is particularly important in long-term projects, by establishing the basis for setting goals and allocating resources within that timeframe.
Example, best practice, and further information
In a multi-year research project, for example, the planning horizon might be set to five years in order to plan long-term research goals and the required resources for that duration. A best practice is to define a realistic planning horizon and to review and adjust it regularly throughout the project. This approach aligns with the principles of time management according to the PMBOK Guide and with rolling-wave planning in agile methods, allowing teams to respond flexibly to changes.
