Withthe WBS element of the least significant level in the WBS each branch, it is the smallest basic unit of the progress control in the project scope where that WBS shows.
As for the work package, when doing project management, being control possible, being something which is set as the unit which has meaning in controlling, as for grain size it is various with the scale and purpose of project.
As for the work package, several activities (concrete job) with specification is defined according to need, can allot the resource of the responsible person in charge and execution organization etc.. Still concrete job and those which the person in charge has not decided the planning package, there are times when those which utilize external order/supply are called the commitment package.
With WBS disassembling result ones/job, it makes the work package, but for example when it keeps allotting the patsy/organization to that work package,OBS is completed. In addition, for schedule compilation when WBS is developed in the network figure, it means to do at the work package or the unit of the subordinate activity.
When with the work package it does to cost management, it is, but with large-scale project collecting several work packages, it sets the control accounton the higher rankof WBS, does budget allotment and cost totaling at this unit.
With large-scale project, every work package the out-sorcing doing, when it allots the other project manager, it is. When it becomes such sub project structure, the work package is the smallest control unit for the superior project manager, being most significant result ones for the subordinate sub project manager, here furthermore it becomes the nest which WBS develops in starting point.
Essence of the work package is "the control unit with respect to management", butthere isthe delicate difference depending upon various methodologies and the difference of standard e.g., with PMBOK "() result ones of WBS lowest layer level", with PRINCE2 "information set in order to make the product" it is defined. In addition, with many project management software it is not the work package, the word such as "task" "activity" is used. |
