What characteristic should goals have according to the SMART criteria?

Goals defined by the SMART criteria should indeed be realistic and challenging. The SMART framework stands for Specific, Measurable, Achievable, Relevant, and Time-bound. Within this framework, setting goals that are realistic ensures that they are attainable given the resources and constraints available. On the other hand, stating that goals should be challenging provides motivation and encourages individuals to push their limits. This balance between realism and challenge aids in personal and professional growth, helping to maintain engagement and dedication to the goal-setting process.

The other options highlight characteristics that do not align with the principles of effective goal setting. Clarity and focus are paramount in goal development, while ambiguity and vagueness can lead to confusion and lack of direction. Goals should be both attainable and challenging to drive progress, and generalization can dilute the focus necessary for achieving tangible results.
