The implementation of the CMGS (Case Method with Guest Speakers) Project in Sales Management courses provides Marketing undergraduate students with first-hand practical knowledge about how a sales manager can deal with a wide variety of professional scenarios. In order to apply this methodology, eight sales managers were invited to a Sales Management Course as guest speakers. Students were required to prepare the sessions, gathering information about the sector and identifying areas of special interest to be discussed. This provided an opportunity for interaction between students and sales professionals. Findings suggest the desirability of employing this methodology in other courses.
