Sales people are expensive to hire. Much like moving house it can be better to get more from what you already have rather than make a change.
Sure, you can send them on yet another training course, the contents of which will have been forgotten by the time you’ve been through a quarter end!
Better we think, to invest in an ongoing program of continuous review and improvement, tied back into your other operations. Sometimes your sales team needs someone to make some internal battles for them.
