A Gallup study of over 250,000 sales people and 25,000 sales managers supports our internal findings that the highest performers use a variety of sales approaches and styles. Even within the same company, many different sales approaches are used by these top performers. In fact, if all the top performers were forced to use a single sales style, many of them would cease to be top producers, would get frustrated and quit. Gallup’s conclusion: No one style is best. Gallup’s study supports our consistent findings: The bank must be flexible enough to allow people to.
