In other words, a certain level of explicit competences is prerequisite of any sales person. However, this paper does not expect a salesperson with strong explicit competences but weak implicit competences can generate good business. In contrast, a salesperson equipped with strong implicit competences but relatively weak explicit competences are still likely to generate good business. According to the core and surface competences described by Broeck et al. (2010), motivations and qualities are the key to job performances. The motivations and qualities they refer to and the motivation for achievements, self-drive, proactive-ness, ambition and aspirations described in this paper are basically the same things.
