Final answer:
Project managers can control costs by creating budgets, monitoring expenses, and implementing cost-saving measures.
Step-by-step explanation:
One of the actions that a project manager can take to control costs is creating a detailed budget for the project. This involves estimating the costs of all necessary resources and planning how those costs will be managed throughout the project.
Another action is closely monitoring expenses and comparing them to the planned budget. This allows the project manager to identify any deviations from the budget and take corrective action if necessary.
Additionally, the project manager can implement cost-saving measures, such as finding more affordable suppliers or optimizing resource allocation, to keep costs under control.
