Final answer:
The true statement about workgroup information systems is that they are easy to change, making them adaptable for small groups. They do not necessarily support only 10 to 100 users, require training, or minimize data duplication among departments.
Step-by-step explanation:
Regarding workgroup information systems, the true statement is C: They are easy to change. Workgroup information systems are designed to be adaptable to meet the changing needs of the small groups they serve. These systems typically support a specific department, project, or team within an organization, facilitating collaboration and information sharing among a limited number of users.
They do not necessarily support only 10 to 100 users, as workgroup systems can vary in size. Also, proper training is often required to use these systems effectively, and they do not inherently minimize data duplication among departments; in fact, without proper integration, they could potentially contribute to data silos within an organization. Instead, workgroup systems' flexibility and ease of modification make them a vital part of modern organizational infrastructure, allowing groups to adjust their tools to best suit their tasks and workflows.
Modern information technologies, such as the Internet, GPS, and GIS, have significantly influenced the development and capabilities of workgroup information systems by enabling advanced data sharing, collaboration, and location-based analytics amongst users within the workgroup.
