You are managing a software engineering project when two team members come to you with a conflict. The lead developer has identified an important project risk: you have a subcontractor that may not deliver on time. Another developer does not believe that the risk is likely to happen, however, you consult the lessons learned from previous projects and discover that subcontractors failed to deliver their work on two previous projects. The lead developer suggests that you have two team members take three weeks to research the component being built by the subcontractor and come up with some initial work that you can fall back on in case that subcontractor does not deliver. You decide to follow the lead developer advice over the objections of the other team member. Which BEST describes this scenario?

a) Avoidance

b) Mitigation

c) Acceptance

d) Transference
