Which type of management system primarily benefits senior executives?

The correct choice is Executive Support Systems because these systems are specifically designed to aid senior executives in their decision-making processes. Executive Support Systems (ESS) provide high-level reports and easily digestible summaries of complex data, allowing executives to monitor organizational performance, analyze trends, and make strategic decisions without getting bogged down in operational details. These systems often include data visualization tools and dashboard features that present information in an accessible way, which is essential for executives who need to grasp the larger picture quickly.

In contrast, Decision Support Systems, while beneficial for managerial decision-making, are typically more focused on specific operational problems rather than the broader strategic view that executives require. Management Information Systems serve to provide regular reports to middle managers and are less tailored for the unique needs of senior executives. Custom Software Solutions can be tailored to any role within an organization but are not specifically designed for the executive level. Therefore, Executive Support Systems are uniquely positioned to capture the needs and requirements of senior executives effectively.
