Why is it important to acknowledge potential bias in estimation?

Acknowledging potential bias in estimation is crucial because it directly relates to the accuracy and reliability of the estimations, which in turn can significantly impact the success of a project. Bias can lead to overly optimistic or pessimistic assessments of timeframes, costs, or resource needs, potentially skewing project plans and decisions.

When estimations are inaccurate due to unrecognized biases, it can result in inadequate budgeting, unrealistic timelines, or insufficient resource allocation. This often leads to project delays, cost overruns, or even project failure, which can adversely affect stakeholder confidence and the overall outcome of the project. By recognizing and addressing bias, project managers can use more objective data and develop more grounded estimates, thereby enhancing the likelihood of project completion within the established constraints.
