prerequisites before task scheduling
- Requirements gathered to the level just enough for estimating
- Determine Risks, Constrains
- Availability of resources
- Make sure the estimates are done by your team and work package is estimaetd by the person who is going to do the real work.
Steps to follow:
- Create a work breakdown structure (WBS). I prefer to use either Featurewise categorization or use Product life cycle categorization. (Dont try to simulate PMI process model in the WBS)
- Create a Ghant Chart or use MSProject
- Estimate Work-packages.
- Sequence the activities (Network Diagram) or User the MsProject Ghant chart itself.
- Run through Forward Pass , Backward pass: You can use either float formula to compute float. Late Finish - Early Finish = 14 - 9 ::: 5, or Late Start - Early Start'" 8 - 3 = 5.
- Determine Float, Total Float
- Resource Allocation
- Level Resources
