Shaft Engineers, Procurement Manger and Engineering Managers from Rustenburg platinum mines were the participants in the study. A total number of eight interviews were conducted on five mines around Rustenburg. The exploratory design and qualitative approach were used in the study. Interpretive phenomenological and semi-structured interviews approach were used. Open ended question were asked, these kinds of questions allowed the participants to engage and participate effectively. The information was analysed using a thematic approach. Heuristics and bias across life span of a decision maker, have influence in the decision-making ability of the decision maker. Engineering Managers and Shaft Engineers are not immune from cognitive bias, heuristics, and their effects during mining equipment selection. Managers must be rational when selecting mining equipment, but the research indicate that under limited time and lack of information, managers turn to cognitive biasness and heuristics (“Mind shot cut”) during decision making. The study shows that the participants with more experience used fewer heuristics than those with less, especially when the stakes were high. These support that the decision maker who have high cognitive level (Knowledge) use their intuitive “gutfeel” to take a calculated risk. The "bounded rationality" of decision-makers has been acknowledged by decision theories, as having cognitive constraints.
