Final answer:
The degree to which an organization achieves a stated goal refers to effectiveness. Efficiency and synergy are related concepts that contribute to an organization's success.
Step-by-step explanation:
The degree to which an organization achieves a stated goal refers to effectiveness. Effectiveness measures the extent to which an organization's goals are accomplished. It is a measure of how successful an organization is in achieving its objectives.
In contrast, efficiency refers to the ability of an organization to use its resources, such as time and money, in the most optimal way to achieve its goals. The more efficient an organization is, the less waste there is and the better it can utilize its resources.
While synergy is also an important concept in organizations, it refers to the collaboration and combined efforts of individuals or groups that result in greater outcomes compared to individual efforts. While synergy can contribute to effectiveness and efficiency, it is not specifically tied to the degree to which a goal is achieved.
