What happens once you use Easy Cost Planning (ECP) for a WBS?

Using Easy Cost Planning (ECP) for a Work Breakdown Structure (WBS) allows for cost estimation and planning within the framework of GFEBS. Once ECP is utilized for a specific WBS, it fundamentally changes how costs are managed and recorded for that structure.

The correct response indicates that after you have engaged with ECP for that WBS, utilizing Structure Planning again is not an option. ECP introduces a layer of cost planning that is distinct and does not mesh with the traditional Structure Planning methods. This means that once you have chosen to use ECP, the process and the associated data structure are linked specifically to ECP's methodologies and functionalities.

Therefore, utilizing Structure Planning for a WBS that has already been subjected to ECP is not permissible because it would create conflicts between the different cost planning systems. This design choice maximizes the efficacy of the cost planning process by ensuring that all principles and practices align with the specific methodology chosen at the outset.
