Final answer:
The NOT true observation about the negotiation planning process is the claim that a single planning process is adequate for both distributive and integrative negotiations. This is false because each type of negotiation requires a different approach tailored to its distinct objectives.
Step-by-step explanation:
The question asks which statement is NOT true about the negotiation planning process. To accurately answer this, we need a clear understanding of the principles and steps involved in such a process. Generally, it involves considering structural and contextual factors that extend beyond the bargaining table, as these can significantly impact the strategies and planning involved. Moreover, there is no one-size-fits-all process applicable to every type of negotiation. While distributive processes (focus on dividing resources) differ from integrative processes (focus on mutual gains), each requires a tailored approach. Finally, experts like Lewicki and others suggest that planning is not a rigid linear process but one that might require revisiting and refining previous steps as new information is obtained or as real-world dynamics shift.
Based on the information provided and the general nature of negotiation planning, we can deduce that the statement claiming a single planning process applies to both distributive and integrative processes is not true. The complexities of negotiation require different approaches for different negotiation types and goals.
