"The challenge comes when *someone* (it doesn't matter who, but they often count beans for a living, decides that the carefully prepared plan "takes too long" and needs to be done in less time."
A secondary issue is that the 'plan' doesn't make economic sense if properly specified to the correct hardware/network/redundancy/DR/day-to-day debugging capability; the imaginary savings are much sweeter if they use imaginary numbers for capacity and support cost.
Imagine that!
