The Project Initiation Stage must also define what resources and associated time commitment are required to carry out the project. The work breakdown structure provides a basis from which this estimation can be carried out. The resource and time commitment can be used to calculate an end date for the project and an estimate of its cost. This information is key input into the establishment of a business case for the intended project. The overall project schedule is not at a sufficient level of detail to enable the allocation of actual resources to tasks, or to control progress. It is necessary to produce a more detailed plan.
