Throughout the various project performance domains, there is a need to recognize bias, identify the root cause of problems, and consider challenging issues, such as ambiguity, complexity, and so forth. Critical thinking helps to accomplish these activities. Critical thinking includes disciplined, rational, logical, evidence-based thinking. It requires an open mind and the ability to analyze objectively. Critical thinking, especially when applied to discovery, can include conceptual imagination, insight, and intuition. It can also include reflective thinking and metacognition (thinking about thinking and being aware of one’s awareness).
