Final answer:
In the early stages of a project lifecycle, according to Thamhain et al., the greatest intensity of conflict is often associated with priorities, which can lead to significant challenges if not managed effectively.
Step-by-step explanation:
During the early program phases of the project lifecycle, Thamhain et al. suggest that conflict intensity is the greatest with respect to priorities. Conflict during these phases often arises due to different individuals and groups having conflicting views on what should be prioritized. This can be further complicated by various factors such as work overload, difficult work relationships, and ambiguity in defining managerial roles. Also, disagreements over resource allocation and values can create conflicts, necessitating effective bargaining and negotiation skills. It is important to manage these conflicts effectively since unresolved conflicts can lead to stress, decreased morale, and lost productivity.
