Questions
You can raise a hand!
Problem 1: Focus only on Cost
“As I hurtled through space, one thought
kept crossing my mind - every part of this
rocket was supplied by the lowest
bidder.”
― John Glenn
Problem 2: Attention only to Modules
What Should Happen!
What Should Happen! What Actually Happens!
Problem 2: Attention only to Modules
