What characterizes a vision that is not measurable or attainable?

A vision that is characterized as lacking concrete goals indeed indicates that it is not measurable or attainable. In effective leadership and planning, visions are most powerful when they incorporate clear metrics or goals that allow for assessment of progress and success. When a vision is vague and does not provide specific outcomes or directions, it becomes difficult to determine whether it has been achieved or how to move towards it effectively.

A vision should have characteristics that enable individuals or organizations to see what they are working towards in a concrete and tangible manner. Without concrete goals, it remains an abstract idea that does not guide actions or decisions effectively. Thus, option B captures the essence of a vision that fails to be measurable or attainable, as it emphasizes the absence of clearly defined objectives that would allow individuals to gauge success or understand the steps needed to achieve the vision.

In contrast, other options highlight attributes of a good vision but do not address the core issue of measurability and attainability. For instance, being clear and specific or achievable with resources indicates a well-formulated vision, while inspiring confidence underscores an emotional connection rather than addressing whether the vision can be quantified or reached.
