A project can have plenty of capable people and still stall because everyone expects someone else to make the call. Naming a single accountable decision maker gives a question somewhere to land. Others may investigate, advise, disagree, and carry out the work; one person is responsible for choosing and explaining what happens next.
This is the logic behind a directly responsible individual. The role attaches to a particular decision or outcome, not necessarily to the most senior person. A community festival might give one organizer responsibility for choosing the venue within an agreed budget, while accessibility volunteers and performers supply requirements.
