OK, perhaps NASA doesn't like to improvise repair
procedures as a fundamental way of doing business.
Why would improvization be such a goal and a virtue?
Improvisation is a matter of necessity.
Speaking as one who has maintained equipment far from support and with
limited resources; A routine need to improvise is a sign of poor
design and engineering. If it becomes a necessity, it's a sign that
something is badly wrong.
