A method and associated systems for automatically identifying a risk that a staffing resource identified by a proposed project-staffing plan will be unavailable. A computerized project-management tool, in response to receiving a proposed project plan, requests, receives, and aggregates information about other past, present, and expected projects and about expected supplies of, and competing demands for, staffing resources required by the proposed plan. The tool infers patterns, business rules, and trends from the received information, with which it adjusts the proposed project's planned start date, expected availabilities of required staffing resources, and expected competition for staffing resources. The tool then determines a likelihood that a sufficient supply of each of the plan's required staffing resources, as adjusted, will be available at the required times, as adjusted. If the risk is too high, the user may fine-tune the proposed plan by repeating the preceding steps with varying project parameters.
