The cost baseline is developed during which process?Develop scheduleDetermine budgetEstimate costsMonitor & control project work

The correct answer to the question is "Determine budget."

Explanation:

The cost baseline is a key element of project management that serves as a standard for measuring project performance. It is specifically developed during the "Determine Budget" process.

1. Project Management Phases: During the project management process, the project manager estimates the costs of resources needed to complete project activities. After these estimates are determined, they are aggregated to establish the budget for the project.

2. Cost Baseline Development: In the "Determine Budget" process, costs are compiled and analyzed to create a time-phased budget that represents the project's cost baseline. The cost baseline helps in monitoring and controlling project costs and provides a reliable measure against which actual performance can be compared.

3. Other Processes: The other options listed:

   • "Develop Schedule" pertains to establishing timelines for project tasks.
   • "Estimate Costs" is about calculating the probable costs of resources.
   • "Monitor & Control Project Work" involves tracking project performance against the baseline.

In summary, the cost baseline is formed in the "Determine Budget" process, which consolidates the estimated costs into an approved budget for the project.
