The Peter Principle Management Theory

Don’t be the meat in the Peter Principle Sandwich:
Peter Principle Theory

By: Harry H. Holdorf

The Peter Principle is a management theory in which the selection of a candidate’s performance is based on the candidate’s performance in their CURRENT role rather than on abilities relevant to the intended role.

HENCE, employees only stop being promoted once they can no longer perform effectively, and…

“Managers rise to the level of their incompetence.”                                                                                                                -Raymond Hull

“A gentle answer turns away wrath, but a harsh word stirs up anger”                                                                                                                -Solomon

Good Leadership practices seem to evaporate in the air when those promoted into lofty positions are faced with making decisions that they exclusively own.

How does true leadership work? It is not generated by your title. In fact, being named to a position is the lowest of the levels every effective leader achieves.

To be more than a boss that people are required to follow, the successful leader must master the ability to inspire and invest in people. You need to build a team that produces not only results, but also future leaders.

With skill and dedication, you can reach the pinnacle of leadership-where your influence extends beyond your immediate reach for the benefit of others.

The levels of leadership are the following:

  • FIRST LEVEL: You have reached a position in which people follow you because they have to. If not for these rights, people may choose not to follow you.
  • SECOND LEVEL: People now follow you because they want to. You have developed a relationship with your team: they have permission to follow you and they choose to do so.
  • THIRD LEVEL: People follow you because of what you have done for the organization. You have produced results and how have some street cred.
  • FORTH LEVEL: People will follow you for what you have done for them. You have lifted them up, and they are grateful.
  • FIFTH LEVEL: You have reached the APEX of a desired management style. People follow you because of who you are and what you represent. THEY RESPECT YOU!!!

Question: What’s the difference between a GO-GETTER and an OVER-REACHER?

Answer: Go –Getters know their limits: Over-reachers don’t.

I have always been an advocate of saying YES if asked to do something. Why?  They usually will only ask you once, and if you say no to one thing, you probably won’t be asked to do anything else.

REGARDLESS, know when to say NO. Perform an honest self audit. Ask yourself, ‘can I really do this job?’

Don’t be the meat in the Peter Principle sandwich. It does not taste so good…

General Purpose Ultrasound Phantom

phantomWonderful for quality assurance labs, you can find it here:

The basic standard for ultrasound quality assurance.

The series of ultrasound phantoms, unlike human subjects or random scannable materials, offers a reliable medium which contains specific, known test objects for repeatable qualitative assessment of ultrasound scanner performance over time. This phantom is constructed from the patented solid elastic material Zerdine®.

Zerdine®, unlike other phantom materials on the market, is not affected by changes in temperature. It can be subjected to boiling or freezing conditions without sustaining significant damage. Zerdine® is also more elastic than other materials and allows more pressure to be applied to the scanning surface without subsequent damage to the material. At normal or room temperatures, the Zerdine® material found in the Model 054 will accurately simulate the ultrasound characteristics found in human liver tissue.

Designed to allow for axial resolution, lateral response width, uniformity, dead zone measurements, depth of visualization, high and low contrast mass imaging, and distance calibration.

Welcome to my brand new blog!

This blog will serve as a new tool for communicating my thoughts and concerns regarding ultrasound and ultrasonography education methods. I will share my classroom experiences, experiments, and successes. Please feel free to participate in the open dialogue of these posts, as this should also serve as a forum for anyone who is thinking about entering the field of medical tech, as well as those who are more experienced veterans. I hope you enjoy and get something out of my blog, I know I will!
