Managing risk
Often I hear people say that Scrum does not take care of risk: there is no risk log, risk is not on the agenda of the Sprint Review or Retrospective as a standard agenda-item. The Developers need to be accountable for the quality of the product and how it's made. And ultimately each role in Scrum has accountabilities that effect risk.
But ... if there is not one person accountable for quality, being on time, within budget, building the right thing... How is risk managed in Scrum?
