In a goal-setting system, commitment is a crucial stage as it signifies the individual's intention to follow through with their goals. When a person commits to a goal, they create a sense of ownership and responsibility towards achieving it. This psychological investment increases motivation and perseverance, which are essential for overcoming obstacles and challenges that may arise during the pursuit of the goal.

Commitment transforms a goal from a mere intention into a determined effort, often leading to more structured planning and action. It embodies the readiness to prioritize activities that align with the goal, thereby facilitating progress and enhancing the likelihood of success.

On the other hand, while evaluation and reevaluation do play important roles in assessing progress and modifying goals, they do not represent a foundational stage in the initial goal-setting process. Consensus can refer to agreement among a group about goals but isn't a direct part of the individual goal-setting system. Generalization relates more to the transfer of skills and behaviors across different contexts rather than a stage within goal setting itself.
