Would you let a doctor prescribe expensive medication without first diagnosing what was wrong with you? Would you tell a mechanic to replace the engine in your car because it was making a funny noise—without first identifying what was making the noise? In both cases you could end up spending a lot of money without actually fixing the problem. Few of us would ever think about doing something like that.
Yet, many companies do essentially the same thing when they throw thousands of dollars into leadership development programs without first trying to figure out exactly what they are trying to fix.
