I have mixed reviews about sales training. I believe the best sales training is the one which helps you better define your own personal style of selling. This may come from taking multiple different sales training courses and taking the best parts from each. My personal favorite styles are those of Covey, Carnegie, Schiffman and Sandler. I”ve taken a litle bit from all of these lessons and along with my college education and personal experience morphed them into a style that works for me. Now some of these styles require you to follow them to the “T” with no improvisation for the best results. I totally disagree with this as sales is not a cookie cuter type function. I like to use these models and guidlines to help the sales presentation flow better and to provide a restarting point if the presentation goes askew. All in all I think that time and expereience (including lots of mistakes) is really the only way to train yourself in being good in sales.
