Which of the following questions would help in predicting a system's operational feasibility?

When assessing a system's operational feasibility, it's essential to understand how the new system will affect current operations and workforce dynamics. The correct answer focuses on the potential outcomes of implementation, particularly regarding personnel changes.

Operational feasibility examines whether the organization can effectively operate the system after implementation, including considerations of staffing, workflows, and employee capabilities. In this context, a question about workforce reduction highlights critical factors such as employee morale, training needs, and the overall impact on operations. If the new system leads to workforce reductions, it can significantly affect the organization's ability to function smoothly and maintain productivity, ultimately failing the feasibility of the system from an operational perspective.

While the other options raise important considerations about customer satisfaction, integration with existing technologies, and data security, these aspects primarily touch on performance, technical feasibility, and organizational benefits rather than directly addressing the operational capabilities and human resources involved in maintaining and running the system effectively. Thus, they are essential but do not specifically answer the operational feasibility question as fundamentally as the aspect of workforce changes does.
