Dependence determination and integration
Mandatory dependency
Discretionary dependency: Soft logic
External dependence
Internal dependence
Leads and lag
Lead: advanced
Lag: delayed

Estimate activity durations
Output
Duration estimation
Basic of estimates: approach and assumptions of estimation
T&T
Analogous estimating: get info from similar activity in historical data
Parametric estimating: time = size / ( productivity * Resource_Number)
Three-point estimates
Triangle distribution: (P + M + O)/3
Beta distribution (PERT): (P + 4M + O) / 6
Bottom-up estimating
Reserve analysis
Heuristic: generally accepted rule (Rita)
Considerations
Law of diminishing returns
Number of resources: double resource not always reduce 1/2 time

Crashing
: Increase resources -> increase cost
Fast tracking
: Overlap -> increase risk
Agile release planning
Control schedule
Purpose
monitoring the status of the project to update the project schedule
managing changes to the schedule baseline
for Agile: it may have meetings for correcting processes and improving
