Final answer:
Concurrent/regular reports are used in business and management for real-time monitoring and decision-making. They are typically leveraged in scenarios like sales performance tracking and project management progress updates.
Step-by-step explanation:
Concurrent/regular reports are primarily used in the business and management fields. These reports are concurrent because they are generated and used simultaneously with ongoing activities. This allows for real-time monitoring and decision-making in the workplace. An example of such a report would be a dashboard that shows the current performance metrics of a company's sales department in real-time. Another instance can be in project management, where team progress reports are regularly updated and reviewed during the life cycle of the project.
