The main purpose of this study was the investigation of the planning processes among individuals of different levels of expertise (i.e., novices and experts) in the machining domain, performing on two different tasks of increasing complexity (i.e., Drawing 1 and Drawing 2). / Twenty-four subjects were assigned randomly to four experimental groups. Subjects were trained to think aloud and verbal protocols were collected as they performed the task. The protocols were analyzed according to a well-defined and reliable coding scheme to identify planning and other operations. / No significant results were found for the planning variable. Significant results were found for the amount of evaluation and writing. Experts appeared to do better than novices in both task conditions. Furthermore, the best performers in all the experimental groups seemed to plan the least. The absence of significant effects of expertise or complexity on planning contradicts the hypothesis derived from the literature. Possible explanations for these results are offered.
