Leading the Leaders by Dr. Ichak Adizes

Leading the LeadersThis book was written to help you discover your basic management style and compensate for your weaknesses so you can work better with others – subordinates, peers, and those you report to – whose management styles are different from your own. It does this by providing prescriptions to follow for each management style, notes from the battleground based on Dr. Adizes’ experiences in coaching executives around the world for the past 40 years.

The Ideal Executive by Dr. Ichak Adizes

The Ideal ExecutiveDr. Adizes’ premise, developed in this book, is that the ideal leader, manager, or executive—ideal in the sense that he can fulfill by himself all the roles necessary for the long-and short-term effectiveness and efficiency of an organization—does not and cannot exist. And that is the problem with contemporary management literature: it presents what the executive should do, (because that is what the organization needs) even though no one can do it. All the books and textbooks that try to teach us to be perfect managers, leaders, or executives are based on the erroneous assumption that such a goal is possible. This book explains why it is not. We are all barking up the wrong tree, spending millions of dollars to train and develop executives based on faulty logic.

Management/Mismanagment Styles by Dr. Ichak Adizes

Mangagement/Mismanagement StylesThis book helps managers identify the style of real people, not imaginary templates, and provides tools to build a team of people with complementary strengths and weaknesses, based on their different management styles.This book provides a methodology to classify styles identify their strengths and weaknesses, and predict how each style will make decisions, staff, motivate, and communicate; in a word, manage.

Read the latest from Dr. Ichak Kalderon Adizes' Weekly Blog.
      • Life is Change
        To start with, can we agree that life is change? We are born, grow and age. Constantly changing physically, emotionally, intellectually and spiritually among many other dimensions.
      • Nepotism vs. Materialism

        I am in Astana, the capital of Kazakhstan. At the Forum for a sovereign state fund, Samruk Kazyna, to discuss organizational transformation.A distinguished British leader of a company with 350,000 employees speaks before me. He is focusing on what he believes is a major fault with the managerial practice in Kazakhstan.
      • Dr. Adizes’ Speech at the Samruk Kazyna Transformation Forum in Astana 

        I have been invited to speak at a forum on how to make a holding company with 350,000 employees and assets of 100 billion dollars competitive in the global marketplace. The goal is straightforward enough: meet or exceed global indicators of success like EVA or ROI. Here is an edited version of my ten-minute speech delivered at the Samruk Kazyna Transformation Forum in Astana.

      • What is Wrong With Business Schools?

        Fifty years ago, when I received my MBA and doctoral degrees at Columbia University Business School, MBA programs were not yet popular. Since that time offers have grown like mushrooms after the rain, especially in Eastern Europe and the developing countries.  What is wrong with that?

      • The Value of Disagreements

        People by and large find disagreement to be disagreeable. Annoying. Upsetting. And in the case of someone who is narcissistic, it is likely to engender belligerence. Why? Because disagreements interfere with our sense or desire for control.

      • How to Compete with E-Commerce?

        By now it is old news that Amazon “killed” the bookstores. We all know that bookstores are closing left and right. It is easier to buy books on the internet. The banking industry is in trouble too. But the impact of the internet is far greater, way beyond books and banking.

      • On Core Competency and Value Propositions
        One of the cornerstones of strategic planning is, of course, to analyze core competencies and value propositions (what value you provide that makes your customers come to you and not to your competitors). We take that for granted. But should it be the responsibility of the CEO? Is that his role in the company?
      • Change and Its Repercussions for The Banking Industry

        Changes have always existed but their speed and frequency have become rather apparent. Changes are present in all areas of life, but here we focus on those happening in the banking industry. Banks are undergoing revolutionary changes and they must change or perish in their present form. The article explains why banks must change and what are the threats to both asset and liability sides they would face otherwise.

      • Growing and Fixed Pies
        Okay, the title is a bit of a teaser. “Pies”, in this instance, are a serious business. When I use the term “a fixed pie,” I am referring to a belief system that assumes that if someone has a bigger piece of the pie, others have less.
      • “IF”

        In my consulting experience, I come across many instances when people in the meeting say “IF” so and so happens than…And, I find this “IF” to be disempowering. It also does not point or direct us to think actively, proactively at what we will do.

      • The Dimension of Time – What is it?
        Bjarni Snæbjörn Jónsson, a doctoral candidate from Iceland at the Adizes Graduate School for the Study of Change and Leadership pointed out to me to an interesting finding.  Here it is in his own words, which I edited.
      • Not All Energies Are the Same

        Calories are related to physical energy. That is the energy we need to operate our body. That is the (P) energy, so to say. Exercise also gives and uses (P) energy.  Whether the exercise leaves you with more net energy or less net energy depends on your physical condition and the degree of exhaustion from the exercise. But there are other forms of energy.

      • Mixing Incompatibles

        We know and have tested the hypothesis that in an organizational structure it is dysfunctional, to mix (P) and (E). Thus, Adizes methodology recommends not to have one VP for sales and marketing in the corporate structure. Why?

      • Attitude for Mutual Trust and Respect

        Mutual Trust and Respect have always played a central role in my thinking and, of course, in many of my books. The reason is simple: They provide the compelling underpinnings that all systems need in order to be successful. And by all systems I mean every kind from an individual (in which case it becomes Self Respect and Self Trust), a family, a business, a society, or even a macro system (meaning a nation-state). I would suggest that the concept applies to the global world as well.

      • What is a “Real” Asset?

        David Tice, a friend and a professor of Business from the University of California, Berkley, in a seminar that we jointly taught in Moscow, made a point on strategic planning which was illuminating. I want to share it with you. What is a real asset of a company? (He used the phrase “real core competence.”)

      • Who Will Succeed?

        There is change. Change means “something NEW is happening.” Whenever something new happens that impacts you, you have  to decide what to do about it, and that includes the decision to do nothing.  You must choose.

      • What Should be the Goal of a Corporation?

        Economists and conservative politicians say the goal of a business is profits–long-term profits. It makes sense: It is a clear goal. It is measurable. It represents the interests of the owners. But it has a problem nonetheless

      • The Fear of…Success

        You probably know, as I do, that fear of failure is a psychological concept. Do you ever wonder how that is possible? How someone can spend his life being afraid of failing? I have come across a different pattern of behavior, of people who fear success.
