In a team where tasks are assigned to different actors, the question of who assumes ownership of how it is progressing and whether the task has been completed is critical.
Accountability, which is a product of responsibility entails that you are able to take stock of what you are responsible for and take the praises and/ or hits when there is an appraisal of the activity.
Being responsible for something motivates us to apply methods that will enhance our chances of excellence. We gravitate towards diligence and peak performance when we are held responsible for tasks.
Therefore, the business in responsibility is ownership of the assigned implementation of programs with a clear, logical path to prosperity.
