There is always much complaining about the biases?introduced?into managing?projects and making the estimates needed to make project decisions. In Kahnemann's?Thinking Fast and Slow, there are three biases. ?
These reasoning, evaluating, or recalling errors produce results different from rational judgment. Cognitive bias results from a systematic pattern of people making rapid decisions. Cognitive biases?are part of our?automatic system of how we think. Because?of that, we don't separate?the thinking processes into a dual system...
System One is an unconscious system that is automatic, fast, and efficient at using the data or experience it already knows. Or - and this is a critical point -?it thinks it knows. System One requires very little energy or attention. System One is what we operate?in. Most of the time, we make decisions. Research shows that we are in System One 95% of the time.
System One is prone to errors, with little awareness of how the decisions are made. System One is?gut feel or?intuition. When System One works, it is because memories?and past experiences?inform the decision. This lays the foundation?for errors since our memories and past experiences are filtered through?what we believe?the situation to be. And, of course, those are biased, filtered, and fed back into System One later, creating more bias in the decision-making process in the future.
Research shows [1] that optimism bias is a primary source of project failure. There is no one fix for optimism bias or any of the other biases on projects. But there are specific, actionable steps that can be taken to expose these biases and prevent or correct the undesirable outcomes [2].
How Can We Improve the Probability of Project Success??
The first step is to recognize that there are immutable principles of managing in the presence of uncertainty.
These principles originate in the following:?

With these business principles of software development and projects in general, we can ask and answer five principles of project success.
A Final Thought??
Software engineering economics is about making decisions related to software engineering in a business context. The success of a software product, service, and solution depends on good business, financial, and risk management. Yet, in many companies and organizations, software business relationships to software development and engineering remain vague. [6]
