A Post by Jay Forte on a not so obvious choice to increase the impact of your learning by training the top performers... Interesting view point. Not sure I fully agree either, because high and low performers can transform, they can grow, they can be re-motivated, etc... But still worth a thoough for sure.
... studies show that the benefit of training the lowest-performing employees is minimal; typically they’ll only improve marginally, while the cost and effort that goes into that training can often be too great to outweigh their slightly improved performance. That’s a poor return on investment.
But when we work with our best performers — those who are already good at what they do and interested in improvement — we have the potential to improve their performance exponentially. Our education and effort now yield more significant results and a greater return on our education and human capital investment.
