How can the effectiveness of a mission be evaluated?

Evaluating the effectiveness of a mission primarily revolves around whether the intended objectives were successfully achieved. This involves analyzing various aspects of the mission such as whether the key goals were met, the level of success in tackling challenges, and the overall impact of the mission's outcomes. Achieving mission objectives is a clear indicator of effectiveness because it demonstrates that the mission not only had clear targets but also succeeded in fulfilling them.

While other options may provide useful insights into different aspects of a mission, they do not directly assess the overarching effectiveness in terms of outcomes. For example, comparing costs versus benefits might offer a financial perspective but won't necessarily reflect the mission's success in fulfilling its primary purpose. Similarly, assessing leadership styles or team member conduct may reveal valuable information regarding the process or environment during the mission, yet these factors don't directly correlate with the actual success in accomplishing set objectives. Hence, focusing on whether the mission objectives have been fulfilled provides the most comprehensive evaluation of effectiveness.
