Risk refers to situations involving uncertainty of profit or loss. There are four types of risk control: accept risk, mitigate risk, eliminate risk, and transfer risk. Accepting risk means stakeholders approve taking on a risk, like a project failure. Mitigating risk reduces risk to an acceptable level, like assigning experienced managers to a project. Eliminating risk reduces risk to zero by stopping the risky activity. Transferring risk shifts it to another entity, like purchasing insurance to transfer fire damage risk.
