Getting big sales numbers by cheating customers or creating a false sense of fear can harm your company.
For these shops, my job is simply to formalize their sales process with a Sales Coaching Manual and a Sales Training System. This makes it repeatable with existing techs, newly hired techs and the techs they build from scratch. Selling is just another form of operations. We formalize it in a chapter we write after the operations manual has been written to address how we do our work. It makes selling systematic and teachable to anyone.
