3 methods
Precedence Diagramming method (PDM)
Activity on Node (AoN)
Start-to-start (SS)
Finish-to-finish (FF)
Start-to-finish (SF)
LAG
LEAD
Arrow Diagramming Method (APM)
Activity on Arrow (AoA)
Graphical Evaluation & Review Technique (GERT)
Dependency Type
Hard Logic (Mandatory)
Soft logic (Discretionary)
Preferred way

4. Estimating Activity Durations
Same techniques are used for duration & cost of the activities
Techniques
One point estimating
Analogous estimating
Top-down estimating
Similar historical
No calculation
Bottom-up estimating
Assembling estimations
Parametric estimating
Standard metrics
Industry requirements
Other sources
Historical data
Do Calculations
Methods
Regression analysis
Learning curve
Heauristic
*Three point estimating
3 parameters
Optimistic Estimation
Most Likely Estimation
Pessimistic Estimation
2 distributions
Triangular distribution
Simple/Straight
Estimated Activity duration (or Cost)=(P+M+O)/3
Beta distribution
Weighted Avg/PERT
Estimated Activity Duration (or Cost)= (P+4M+O)/6
Std Deviation=(P-O)/6
↑ Std Dev--↑ Risk
If distribution is not mentioned, assume Beta distribution
Important Points
Padding
Extra time /cost to estimation
NOT ALLOWED
3 point estimating helps!

5. Develop Schedule
Schedule Network Analysis
a) Critical Path Method
Path where any delay will cause delay in total project duration
Float=0
Float/Slack: Other activities can get delayed without affecting proj duration
Total float
Without affecting project duration
Free Float
Without affecting successor's early start date
Project float
Without affecting target Proj duration
Calculations
Start of day notation :check:
End of day notation
b) Schedule Compression
Search for better options
Fast tracking
By rearranging the activities
To run them in parallel
Crashing
Increasing/adjusting the resources
What if both fast tracking/crashing can't be chosen??
Reduce Scope
Cut Quality
c) Monte Carlo Analysis
Simulation
S Curve
d) Resource Optimization
Resource smoothing
Proj duration is considered
Resource Levelling
Proj duration/delay is NOT considered
e) Agile Release Planning
Each iteration=1 feature
