Time Management (6) Flashcards
Estimation types
- one-point estimating
- analogous estimating
- parametric estimating
- three-point estimating (PERT analysis, Program Evaluation and Review Technique)
EAD
Expected Activity Duration or PERT (P + 4M + O)/6
SD
Activity Standard Deviation (P - O)/6
AV
Activity Variance [(P - O)/6]^2
Project Expected Duration or PERT
sum of critical path EADs
Project Variance
sum of critical path AVs
Project Standard Deviation
square root of Project Variance
Range of the Estimate
Expected Duration or Pert +/- Standard Deviation
types of reserves
- contingency reserves
- management reserves
Schedule Network Analysis
used to create the final schedule once the initial one is ready
Schedule Network Analysis techniques
- Critical path method
- Schedule compression
- What-if scenario analysis
- Resource leveling
- Critical chain method
difference between schedule and a time estimate
schedule is calendar-based
total float (slack)
the amount of time activity can be delayed without delaying project end date
free float (slack)
the amount of time activity can be delayed without delaying next the early start of its successor
project float (slack)
the amount of time project can be delayed without delaying the externally imposed project completion end date
