Through my experience, I’ve discovered that the best way to motivate your sales reps to work as a team is by focusing on the company’s vision and mission instead of on their individual quota. It’s more likely that people work as a team when they are pursuing a goal they can’t achieve by themselves, like the company’s mission. While if they focus on achieving something they are able to do on their own (such as their quota) it’s less likely that they will work as a team. Besides, I’ve found it’s highly motivational to involve sales reps on the core of your business.
