These two bits when combined are to me the most at odds with reality: > Although they should jointly discuss the various trade-offs involved in a decision, each decision has a single owner. > When? > Owned by the EM (based on trade-off conversations with the PM). Basically the EM is responsible of delivery date, but doesn't have authority on the business side to adjust for potential timing issues. For instance the PM/EM can agree on a first timeline, but the EM won't be decide to pay for more time in exchange for more business return, or lower running cost. Or to short a project that takes more resources than the expected return. My point is separating responsibility for cost, resources, time, and return is a losing proposition in most settings, as they are intertwined.
