“Welch and Conaty had implemented a 20-70-10 performance ranking system, where GE employees were sorted into three groups: the top 20 percent, the middle 70 percent, and the bottom 10 percent. The top workers were lionized and rewarded with choice assignments, leadership training programs, and stock options. The bottom 10 percent were fired. Under Immelt, the forced distribution was softened and the crisp labels of “top 20 percent,” “middle 70 percent,” and “bottom 10 percent” were replaced with euphemisms: “top talent,” “highly valued,” and “needs improvement.”
