Those who don't embrace change as one of the main factors of sales are doomed to fail. Salespeople often have trouble with the fact that if they manage to finally find the ideal sales technique that works, then they expect it to work forever. The problem is that every technique usually stops being efficient after awhile. Why? Because the clients' expectations, salespeople's attitudes and the whole market keep changing. This is why you have to have a system that will allow your company to assess its activities and processes continuously so that they correspond to how the situation is developing.
