Human factors, like optimism, pressure, and experience, are among the primary reasons for errors in cost estimation. Prejudice can arise when you give preference to certain data or methods and overlook or modify information that doesn't align with your assumptions. Other areas are: Costing data of past similar projects, shortage of competent resources, not analyzing the lessons learned from past experiences, impacts of schedule on incorrect cost estimates.

1?? Lack of Data or Information: Reliance on assumptions, guesses, or intuition due to insufficient data. 2?? Complexity or Uncertainty: Prone to errors, changes, or surprises in complex or uncertain environments. 3?? Bias or Pressure: Influenced by personal preferences, opinions, or external pressures. 4?? Method or Tool Used: The choice of estimation method or tool affects its appropriateness, reliability, and consistency. Understanding these causes helps in addressing estimation inaccuracies and improving the overall project management process.

Estimation inaccuracy by project managers can arise due to several factors. Lack of experience or familiarity with the project domain may lead to underestimation or overestimation of effort and resources needed. Insufficient data or incomplete requirements can also contribute to inaccuracies in estimates. Unrealistic expectations, biases, such as optimism bias or anchoring, and external factors like market volatility or unforeseen risks can further distort estimations. Poor communication, inadequate stakeholder engagement, and limited access to historical project data may also hinder accurate estimation. Ultimately, a combination of these factors can contribute to estimation inaccuracies by project managers.
