This graph isn’t created on a whim or mere observation. We are able to pinpoint each employee’s strengths due to the book Strengths Finder and the test that comes along with it. Developed by Donald O. Clifton, Tom Rath and Gallup Scientists, their research and philosophy points towards how utilizing and recognizing your strengths can help you be a better leader. Similarly it can help you understand those you work with, why they work the way they do and how to compliment each other's strengths.
In the first few pages of the book they share a study which shows that if a manager primarily ignores their employees then the chances of those employees being actively disengaged are as high as 40%. If they focus on your weaknesses, the chances of being actively disengaged are 22%. If a manager focuses on employee’s strengths however, their chances of being actively disengaged drop to 1% (Rath, Tom. Strengths Finder 2.0. New York: Gallup Press, 2007. Print).
This shows that when strengths are being cultivated, people are more likely to succeed. This model then, is an asset to the modern business structure. Creating long term employees that are invested in their work.
