CAPM Practice: Explain the components of an adaptive plan

Last Responsible Moment (LRM) is a lean principle: delay decisions until you have sufficient information but not so long that options are foreclosed. This reduces risk of making costly decisions based on incomplete early information.

**Why not B:** Planning everything at the last minute is procrastination, not LRM. The Last Responsible Moment principle is about timing decisions optimally — waiting until enough information exists to make a sound decision, while still leaving time to act on it effectively. Waiting until deadlines are imminent routinely causes poor decisions due to time pressure and forecloses options that earlier action would have preserved.

**Why not C:** Making all key decisions in the first iteration to enable detailed planning describes the opposite of LRM — it is front-loaded, predictive decision-making. Early decisions carry the highest uncertainty cost because the team knows the least at project start. LRM delays those decisions precisely to exploit the information that accumulates as the project progresses, reducing the likelihood of costly rework.

**Why not D:** Waiting until a deadline is missed before deciding is a dysfunctional pattern, not a planning principle. LRM is defined by acting before options are foreclosed, not after consequences have already materialized. A missed deadline represents the moment after the last responsible moment has passed, making this description a caricature of the principle rather than its application.
