Progress Reports (in Technical Writing Essentials)

"You write a progress report to inform a supervisor, associate, or client about progress you have made on a project over a specific period of time. Periodic progress reports are common on projects that go on for several months (or more). Whoever is paying for this project wants to know whether tasks are being completed on schedule and on budget. If the project is not on schedule or on budget, they want to know why and what additional costs and time will be needed."
