Another advantage compared to activity-based planning has to do with reporting. Products are either finished or not, activities can be 90% finished for a long time

It is important to understand that in this context the term 'product' includes intermediate documentary products that are essential to the work of delivering the project. In this sense the product breakdown structure is a great deal

A significant advantage of product-based planning is the ability to surface critical assumptions and constraints. For example, if your project is to build another floor on top of a house, a required

With an understanding of the deliverables required, and the sequence in which they should be produced, work can then begin on defining the tasks required to produce them.

Product-based planning is intended to ensure that all of the necessary products are identified and captured, and begins by identifying a
