An information system that tracks construction costs for projects across the U.S. would be categorized as which type of system?

An information system that tracks construction costs for projects across the U.S. is best categorized as a Management Information System (MIS). An MIS is designed to collect, process, and manage data to facilitate decision-making within an organization. In this context, a system that tracks construction costs would provide valuable insights into financial management, resource allocation, and project planning, allowing managers to make informed decisions based on timely and accurate information.

While other types of systems like Decision Support Systems (DSS) or Construction Decision Support Systems (CDSS) may also have roles in analyzing trends or supporting specific decisions, the primary function here is tracking and reporting data related to construction costs, which aligns more closely with the objectives of an MIS. A Geographic Information System (GIS) focuses on spatial data and mapping, which is not the primary purpose of the described system. Therefore, the classification as an MIS is appropriate given its focus on managing and streamlining information relevant to construction projects.
