Companies are evaluated and remembered by their people, not their products and services. As long as customers experience excellent service, they will remain loyal.
According to The People Principle, people are what determine preference and profit. To raise your service level, first consider the people on your team. You should not only have the right people, but also the right people in the right places.
The best employees are those well suited for their positions in terms of skill and interest. When workers enjoy and take pride in their position, they will reflect that level of respect onto the customer.
