InfoWorld has a great write-up about a data-center project & what they learned from it. I’ve summarized and abstracted it here:

When you don’t know, you trust.
Differing experiences & personalities will trust different things:
D: themselves
I:  people: what they can get others to do/say.
S: what others say/face-value?
C: the information: their mind/face-value of what others say. They will not try to influence or change.

Details always trip you up:
Practical: some times things just don’t work.
–Execution problem
Idealism: some times you just didn’t think or plan enough (and you could have).
–Information problem

Consequences:
Think + Do everyone’s job in the process, from vendor information, estimations, ordering, manufacturing, shipping; environmental surroundings; temporal surroundings (future-proofing)

Information Errors can be minimized by having a diverse enough team that can think through each step, and communicate (listen!) enough to take each info-tid-bit to heart. Most personalities aren’t capable of valuing this, and those that are, aren’t usually forceful or influential enough to make their case known. Solution? Humility.
