Career: The “Suit” in technical/creative environments
Industry Duration
Visual Effects 1992 to AFO
Internet Startup 1995 to bubble burst
Defense 2000 to current

5. Who Creates Value?
The Suit: Plan, Manage (cost, schedule, risk, scope), Coordinate,
Customer Development, Marketing, Payroll, Benefits

Industry Thing 1990 2013

you don’t need as many “suits”.
