Which of the following is considered a main planning risk?

The selection of undefined scope as a main planning risk is pivotal in project management. When the scope of a project is not clearly defined, it leads to various challenges that can derail the planning process and overall project execution. An undefined scope can cause confusion among team members regarding project deliverables, timelines, and resource allocation. It can also result in scope creep, where additional features or tasks are added without proper evaluation or adjustment of schedules and budgets. This unpredictability can adversely affect project success, leading to increased costs and extended timelines, making it essential for project managers to establish a clear and well-defined scope from the outset.

In contrast, excessive documentation, high team motivation, and frequent stakeholder feedback, while they can pose specific challenges, typically do not constitute main planning risks in the same way undefined scope does. Excessive documentation can often lead to inefficiencies but does not directly affect the project's core capabilities. High team motivation is generally a positive attribute that can enhance project outcomes, and frequent stakeholder feedback is crucial for aligning project objectives with stakeholder expectations, helping to steer projects in the right direction. These other factors, while important, do not inherently threaten the project's planning phase like an undefined scope does.
