Final answer:
The acronym 'POEBALL' stands for seven main user groups considered in system design: Primary, Operational, Executive, By-standers, Aligned, Linked, and Local, each with distinct interactions and interests in the system.
Step-by-step explanation:
The acronym 'POEBALL' represents the seven main user groups that systems analysts consider when designing a system. These groups are: Primary, Operational, Executive, By-standers, Aligned, Linked, and Local. Primary users are the main users who directly interact with the system. Operational users are involved in the daily operations and the administration of the system. Executive users are the managers or directors who make decisions based on system outputs. By-standers are those who are indirectly affected by the system. Aligned users are external stakeholders with a vested interest in the system's output, such as regulators or partners. Linked users are connected to the system indirectly, possibly through data exchange. Local users are physically close to where the system is in use and may be affected by its operation.
