Portfolio initiatives is a structuring tool in PPM. Initiatives are independent objects, similar to portfolio buckets and portfolio items, that can summarize data from assigned items and can be used for overall planning.
Unlike portfolio buckets, which have a more static structure, initiatives can also be used operationally. A portfolio initiative contains an actual start date and phases that structure the time of the process. It is due to this operative character that a portfolio initiative is also similar to a portfolio item.
For example, you find decision points in both objects. However, there are also differences. An initiative is designed for aggregation, whereas an item can also carry out concrete resource planning.
From a technical perspective, a portfolio initiative is an interdependency of a portfolio item and portfolio project. However, it is only designed to map certain functions, such as financial planning. A portfolio initiative is an interdependency only from a technical perspective; it has neither all the functions of a project nor all the functions of a portfolio item.
