Most postmortems fail before anyone speaks. The team is already too depleted to tell the truth without turning it into blame.
That is the point of the Fallow Interval. A field that is always harvested becomes barren. Teams do too. Run Time burns more than hours; it burns the slack people need to hear criticism without treating it as attack. The rule is simple: cool first. Metabolize second.
Then Beautiful Heat matters. Beauty is not decoration. Story, naming, and a public record of what died give loss a form people can bear. It makes pain sayable without choosing a victim.
Skip either step and “renewal” becomes another form of extraction. In a high-change environment, leaders who cannot create fallow and heat will burn trust faster than they build capacity.
