What characteristic should goals have according to the SMART criteria?

Goals should be realistic and challenging in order to effectively align with the SMART criteria. The SMART framework emphasizes that goals must be Specific, Measurable, Achievable, Relevant, and Time-bound. Within this framework, "realistic" indicates that the goals should be attainable and feasible, given the resources available and the context in which they are set. This ensures that individuals or teams can strive toward them without setting themselves up for failure.

At the same time, being "challenging" is vital because goals must push individuals beyond their comfort zones, encouraging growth and development. If goals are merely easy or too attainable, they may lack the motivational aspect necessary to inspire effort and progress. Therefore, a well-balanced goal that is both realistic and challenging can drive individuals to achieve their full potential while still being grounded in actual capabilities and circumstances.
