Project plans
The IMP and IMS represent the project plans that address the technical work to be 
performed. The IMP provides an integrated, hierarchical view of important tech-
nical efforts (activities, high-level tasks, reviews, and milestones). The IMP is not 
a date-driven plan but is characterized by technical results that must be achieved. 
Each effort must be defined by explicit results and the associated criteria that will 
be utilized to confirm attainment of the desired results. The IMS is derived from the 
IMP and provides additional levels of detail for tasks that are necessary to accom-
plish technical results. The IMS aligns anticipated start dates, durations, and rela-
tionships of tasks to other tasks to provide a network of integrated tasks. The IMS 
provides a calendar-based view of the task details necessary for the execution, mon-
itoring, and control of project progress. The IMS must be directly traceable to the 
IMP and must be linked to the WBS.
