What factor contributes to higher estimates in a project review process?

Higher estimates in a project review process are influenced significantly by increased project scope. When the scope of a project expands, it typically means additional tasks, resources, and time are required to complete the project. This expansion may lead to greater complexity and necessitate more materials, specialized labor, or technologies that were not initially part of the plan. Consequently, each of these factors raises the overall cost estimate for the project as stakeholders assess the implications of the larger scope.

Increased labor availability, better resource management, and cost-cutting measures tend to lead to lower overall project costs or efficiencies rather than contributing to higher estimates. These factors typically indicate improved conditions for project execution, thereby making it easier to stay within or even reduce the original budget.
