EM.411 meeting Bryan Moser program management
Relationships in project systems
NASA, Mercury to Apollo
Von Braun
Any good teams have belonging, pride, group, and an element of spontaneity to them
More cultural and organizational view
Bob McNamara
Brought in the “Whiz Kids”
using statistical techniques to improve efficiency
used Work Breakdown Structure
More technical and optimization focused
like Frederick Taylor
Work Breakdown Structure
a decomposition of work
tree structure
identifies “terminal elements”
Cartesian closed category
Bryan Moser
Detail and certainty are not the same thing
Waterfall
Each step still has a verification
There are feedback loops
Similar to the System Engineering V
If you remove the left to right assumption of sequential steps, it looks a lot like agile
Dependencies
if there are no dependencies, does it need to be managed?
Precedence relationships
Finish to start, finish to finish, start to start, etc
similar to necessary / sufficiency relationships
Finish to finish is like necessary but not sufficient
QFD
DSM
rows are tasks / activities
can identify sequential, parallel and coupled task sets
Visualizations as dimensions
dimensions
left to right
top to bottom
networks
size
etc
what’s interesting is if you can have visualizations that communicate more value per dimension
Category Theory
dependence, sequence, connectivity, terminal, initial are all communicated
it’s “easy” to add dimensions
Bryan Moser ideas of dependence
precedence is a result not a cause
dependence as “area of demand”
can represent dependency between processes with a 2d chart where each axis is the time progress on each task
if there is no dependence, all paths from start (bottom left) to end (top right) are available
dependence represented as a “bottom-right” space of the chart
route of actual work and proximity to “area of demand” indicates how efficient the actual work is
also how fragile the coupling is
can represent mutual dependencies with a dependence area on the “top-left” space
->
this is a very interesting idea related to Visualizations as dimensions
