Final answer:
An activity in a business or project management context comprises a set of tasks, which are the smallest units of work subject to management accountability. These tasks correspond to behaviors or practices required or expected of team members, all of which align to achieve a set goal such as resolving commuting issues.
Step-by-step explanation:
An activity comprises a set of tasks (the smallest unit of work subject to management accountability). When you are responsible for a particular process and/or outcomes within a job, it is understood that your manager has set clear expectations for you. While the method of achieving these outcomes may be at your discretion, the importance of meeting the goals is imperative. This reflects the concept that there are behaviors or practices that are either required for or expected of the members of a particular group. In the context of business and project management, these tasks represent the fundamental elements to which one is held responsible.
In the scenario of a design team developing a solution to improve the commuting experience, each member might be assigned specific tasks. The collective completion of these tasks should align with the broader goal, such as addressing a problem statement that describes the issue which the design team intends to solve.
