Commitment is the process of making a promise or personal commitment to something, someone, or even yourself. In the workplace, commitment is in reference to the organisational goals, engagement in the organisation, and efforts to achieving those goals.
Role commitment is the responsibility you may feel to the mission or goals of your team, your department or the organisation. This level of commitment drives an individual to perform their tasks and fulfill their responsibility to meet their goals.
Commitment is often a mindset or holding yourself accountable, and focusing on what is important. It means there is a clear vision of goals that you can commit to you and a direction you can follow.
