Timing is invisible architecture; remove it and even good plans collapse.

Timing is the part of a plan nobody writes down. The strategy can be sound, the people capable, the resources sufficient, and the whole thing still fails because it happened in the wrong month. Because timing is not listed among the components, its absence gets diagnosed as something else entirely.

When you next plan something, treat timing as an explicit element rather than a background condition. Write down why this period and what would make it wrong. Then check that assumption as you go. It is the piece most likely to change without warning and most likely to be blamed on the others when it does.
