What your boss doesn’t want to tell you but you need to know

Ever wonder why so many people seem to be incompetent in their jobs? Although it was famously explained in a humorous book titled The Peter Principle, there’s an important kernel of truth in it that we all need to chew on. The Peter Principle says that everyone in an organization gets promoted to the level of their competence.

So if you are doing a good job, you get promoted — and promoted again, until you start screwing up at which point you’ve reached your ultimate destiny in the company, your “level of incompetence”.

they made me the bossThe joke is that work is accomplished by those who have not yet reached their level of incompetence. The Peter principle is no joke, however. The truth is that your strengths lift you up and your weaknesses weight you down. Think of a hot air balloon. It rises until the lift from hot air is in equilibrium with the weight of its ballast. In the same way, as you rise up in the company, your weaknesses eventually limit your ability to rise further.

Understanding how your strengths and weaknesses shape your career will help you work smarter and find the right intersection where your needs meet those of the company and your boss. Here are some of subtleties to consider:

  • Your strengths and weaknesses are all relative to a specific environment. Your strength in one situation may be a weakness in another. In my company, our culture places a great deal of emphasis on performance, but not ‘at any cost’ because we value integrity and teamwork also.  As a result, focusing on results at any cost would be perceived as a weakness in my company, but could still be a strength in another organization.
  • Your strengths and weaknesses are also relative to the position you hold. If you like to spend your day talking to other people, that would be a strength in our sales team but a weakness for a computer programmer.
  • As you rise up, your personality has a greater impact on the performance and motivation of the people around you. Senior managers typically reach the stall-point in their careers because of limiting personality traits. More bluntly, their personality flaws and undesirable behavior eventually hold them back.

your incompetent bossWhat kind of traits and behaviors would prevent you from becoming a CEO? Some are the same issues we covered in other lessons – too arrogant, doesn’t listen, too confrontational, not flexible enough, too much of a risk-taker, too controlling, and dislikes communicating.

It’s very common for successful individuals to have both strong strengths and strong weaknesses – they often go together. It’s also true that you can reach the stall-point in your career when you lack critical functional experience, in sales or engineering, for example.

This is because many successful people are driven by some type of trauma from their childhood. As a result, they are motivated by fear, need to be in control or desire for recognition and status. This can be as simple as someone driven to avoid the conditions they experienced as a child.

handling criticism at workWhy the psychoanalysis?

  • First, if your strengths flow from a reaction to childhood trauma, you need to know that your strengths taken too far become weaknesses – weaknesses that you will have difficulty seeing.
  • Second, if you are stalled because of a strong weakness, improving your strengths will accomplish little.
  • Third, your boss is unlikely to want to talk about these type of weaknesses with you. Your commitment to seeing your weaknesses and reducing them is critical to your advancement.

    It is important to know what one’s strengths are. A strength in one industry may be a weakness in another industry. In my current position, a weakness of mine is unwillingness to accept criticism. I know that is a fault of mine but when it is delivered as you keep doing such and such wrong without any advice how to change said deficiencies, trying to change becomes difficult. Accepting one’s faults, learning from them, and improving are all necessary traits for success in business as well as in life.

    Acknowledging one’s own strengths and weaknesses involves a degree of wisdom and empathy. I believe it is difficult for many people to think introspectively and thus they often struggle to overcome problems that are really internal. This article encourages people to analyze their strengths and weaknesses in order to use their time more efficiently and make decisions that will have a positive influence on their lives.

    Thank you for sharing this interesting point of view. One of the hardest things in life is to truly admit our weaknesses mainly to ourselves and work on improving our strengths. If one could reach the point of of being honest and willing to improve either part she or he is on a good way to reach her potentials.

    I believe that personal growth, within the workplace, can help shape who you are outside of it. Knowing and

    understanding yourself is one thing, but to be honest about those traits will enable you to enhance strengths and grow in

    your weakness. If you are honest about who you are, then you can better analyze your work environment and how it is

    that you best fit in.

    I have learned that it is extremely important for you to really recognize what your strengths and weaknesses are in reference to the given situation or task at hand. If you focus on improving your weaknesses which is just as important, if not more so, than focusing on just your strengths because ignoring your weaknesses will not make them go away. And we tend to ignore our weaknesses, we could have less weaknesses if we turned them into strengths.
