A software development project team was preparing for a phased release when an unknown and unexpected risk occurred with potential for delaying one of the features for the planned release. The project team decided to go ahead with the release and address this missing feature at a later date. One of the end users learned about this and strongly opposed the planned release. What should the risk manager have done to prevent this situation? Performed proper risk identification at the project outset to ensure this risk was identified and mitigated. Engaged the sponsor and informed them of the decision to remove the planned feature. Engaged the stakeholders more in risk management activities and decisions to get their buy-in and support. Created a schedule buffer in the plan to deal with unknown risks if and when they occurred
