Private risks refer to project risks that relate to personal or confidential issues that could damage relationships or morale if widely known. Examples include team member disputes, life events, or confidential company information. Without trust, private risks cannot be expressed. Trust is difficult to measure but its absence is easy to detect. Communication is key to increasing trust and managing private risks. Focused communication of goals, rewards, and risks down and up the management levels can help build trust to facilitate private risk reporting while protecting confidentiality. If trust is already lost, being consistent, finding informal leaders, and potentially restructuring teams may help reform the environment.
