A project manager on a construction project is asked by the company owner to produce cost estimates for a new decoration project within 4 hours. How can the project manager complete this task?

The correct answer is to tell the owner that a Rough Order of Magnitude (ROM) will be provided. Given the extremely tight deadline of 4 hours, a detailed, accurate estimate is impossible. A ROM estimate is a high-level, preliminary estimate, typically in the range of -25% to +75% accuracy, suitable for early project stages when little information is available. This approach manages expectations while still delivering a requested estimate within the constraints. Calling a meeting with the project team would consume most, if not all, of the allotted 4 hours without necessarily producing a usable estimate. Contacting an SME might provide some input, but a comprehensive estimate still requires more time and data. Telling the owner the task requires more time and expertise is true, but it doesn't offer a solution or attempt to meet the request, which is a key responsibility of a project manager.
