The Three-Minute Budget

An executive reads forty to sixty documents per week. Each one competes for a finite attention budget. Research consistently shows that executives spend an average of three minutes on an intelligence brief before deciding whether to read further or move on. The first thirty seconds determine whether the brief gets the remaining two and a half minutes. The BLUF statement must land in those thirty seconds. Every second of the remaining two and a half minutes must add actionable value or the executive will disengage.

This is not a complaint about executive attention spans. It is a design constraint. An architect does not complain about gravity — gravity determines the design. The three-minute budget determines the brief design. Information density must be calibrated so that three minutes of reading delivers a complete understanding of the finding, its evidence, and the recommended action. If it takes ten minutes, the brief is over-written. If it takes thirty seconds, the brief lacks the evidence to be credible.
