13 Project Planning -- Schedule
* 07/16/96 Project Planning -- Schedule Work Breakdown Structure (WBS) Level-by-level subdivision of work to be performed in a contract Common framework or outline Complicated task is subdivided into several smaller tasks Process continued until task can no longer be subdivided *

14 Project Planning -- Schedule

20 Project Planning Tools – CPM/PERT
* 07/16/96 Project Planning Tools – CPM/PERT Critical Path Method (CPM) DuPont (1958) deterministic task times activity-on-node network construction Project Eval. & Review Technique (PERT) US Navy, Booz, Allen & Hamilton (1958) multiple task time estimates activity-on-arrow network construction *

21 The Project Network Network consists of branches & nodes Node 1 2 3
* 07/16/96 The Project Network Network consists of branches & nodes Node 1 2 3 Branch *

22 * 07/16/96 Network Construction In AON, nodes represent activities & arrows show precedence relationships In AOA, arrows represent activities & nodes are events for points in time An event is the completion or beginning of an activity A dummy shows precedence for two activities with same start & end nodes *

23 Guidelines for dividing tasks into activities
* 07/16/96 Guidelines for dividing tasks into activities Length of each activity should be ~ % of the length of the project; Exception for critical activities; # of activities should be less than 250 *

24 Estimating Duration of Project Activities
* 07/16/96 Estimating Duration of Project Activities Stochastic Approach (past data available) Deterministic Approach (past data available, variability negligible) Modular Technique (decomposing activity into sub-activities) Benchmark Job Technique (repetitions of activities) Parametric Technique (cause-effect) *
