Recently, Mike who is the president from a big company in El Salvador told a story during a staff meeting: when he was in fourth grade he had an English teacher (his native language is Spanish) who was constantly tormenting him about his performance in the subject. He just didn't seem to get it. His teacher didn't have the patience to guide him through the course as he needed extra help and the natural skill for learning a second language just wasn't Mike's strength.
So Mike took matter in his own hands and set out to make an extra effort. He would dedicate an extra hour or two daily with the sole purpose of learning the foreign language. But results didn't show. He failed the tests and his improvement was slow.
After months of trying, he came up to his teacher and told him "I've been trying real hard to pass your course and learn but I just don't seem to get it. What can I do? I'm trying very hard!" To which his teacher replied "Too bad but I'm not grading your effort. Your grades are based on results".
He told this story to his staff to point out that no matter how hard they tried, if they didn't deliver results, they didn't have a future in the company.
I think there are two misconceptions in this story:
First, if your staff doesn't deliver the expected results it's more likely that there's a leadership problem, rather then lack of capacity. In the story the teacher doesn't have the patience to help a student who has difficulty learning a subject. This doesn't mean his not able to learn, this only means he has to learn in a different way or maybe needs more guidance than other students. So this is a clear leadership issue. As a leader you have to identify inside your organization your employees skills and assign them in the right positions. You have to make sure they have proper training as well, but it is your responsibility as a leader to develop people in your staff.
Then we have the effort issue in this story: rewarding effort is a basic element that enhances performance and develops creativity. You have to make sure the efforts are focused and aligned with the company's objectives and goals, but again you as the leader have the task of guiding those efforts and convincing people to go down the right path.
Remember, when you become a good leader your employees will certainly deliver the results you expect.
