EM.411 meeting Bryan Moser program management
Critical path method
Building a project graph is a lot like a Cartesian closed category
Or maybe I mean a preset category
Slack
Some things are more important than others
The difference between earliest and latest start
Smallest slack is the critical path
This is a method for prioritization
Manhattan Project
Phillip Morrison
Bryan Moser studied with him
Set based projects
Is a concept
Delay design decisions as long as possible
Eliminate options over time
Maintain Optionality
PERT
Treats durations as probabilistic
Unlike critical path method which is deterministic
Optimistic, most likely, and pessimistic estimates
Use beta distribution
Choice of alpha and beta in distribution should be informed by priors
For each tasks
When combining tasks you get a summed normal distribution
You can get confidence of completion date from this summed normal
