Several decades ago, a passenger jet approached a Florida airport with the pilot and co-pilot struggling to fix what they thought was a malfunctioning landing gear. The landing-gear light was on, signaling that the gear was deployed; but both men did not hear it actually deploy.

As the men sought to understand whether they had a defective landing-gear light or a defective landing gear -- the co-pilot actually taking up a hatch and getting down into the wheel well -- the aircraft kept losing altitude. Too late, a warning alarm sounded and the plane crash, killing all aboard.

Quite possibly that tragedy has subsequently saved many lives. For the pilot and co-pilot's actions have been used in flight simulation training programs to demonstrate how NOT to troubleshoot problems in the cockpit.

The incident has become known as the Landing-gear Fix, a diligent attempt to solve the wrong problem. Of course, they had a landing-gear problem on their hands. But unbeknownst to them, they faced a far more serious problem, a pending crash.

The Landing-gear Fix is a leadership lesson. In the quest to get results, many leaders often focus on Landing-gear Fixes -- putting their time, resources and talents into solving wrong problems. In fact, it's been my experience working with thousands of leaders during the past 20 years that most leaders are either working on the wrong problems or working on the right problems in the wrong ways.

In this issue, I'll give you a tool to avoid getting involved in a leadership Landing-gear Fix. It's a tool that will help you avoid wrong problems and focus on the right ones. It's called the 20/60/20 rule. And it will save you aggravation and help you avoid wasting time.

When you are leading a group of people of whatever size to get results, understand that roughly about 20 percent of the people are intractable; they won't do -- or at least won't want to do -- what is required. Another 20 percent will be your ardent cause leaders in getting it done. And 40 percent will be on the fence.

How does this rule help you focus you on the right problem? For one thing, it gives you a template of where to put your time and resources.

I wish I had known about the 20/60/20 rule early in my leadership endeavors. In the military and later in other venues, I often gave inordinate amount of attention to people at the intractable end. That people were upset with me and my leadership and the direction I wanted to take organizations upset me
