Agility is defined as the ability to embrace and respond to change quickly and effectively. It is a core principle of agile methods, enabling organizations and teams to adapt to evolving business needs, customer feedback, and external factors while delivering value continuously.

This definition contrasts with traditional change control, which often aims to prevent changes (C). Agility promotes flexibility, learning, and continuous improvement, but the belief that anyone is capable of learning (D), while important, is a cultural aspect rather than a direct definition of agility. The sequence of actions (A) relates more to processes than agility itself.

Understanding agility as the capacity to adapt ensures project approaches remain relevant in dynamic environments.
