Process Communication is about managing relationships.

It helps you to identify and understand personality differences in communication.

PCM is about managing relationships

The Process Communication Model® takes into account the unique characteristics of each individual in order to achieve successful cooperation. It provides a reliable and statistically validated method of identifying and understanding personality differences.

It teaches skills to manage the resulting behaviors (both positive and unproductive ones linked to the various personality profiles).

Based on a scientific award–winning clinical discovery, the PCM model has been the object of research for over thirty years. Close to a million people on five continents have received training on the model which has found applications in a variety of areas such as management, sales, recruitment, negotiation, law, education, politics, religion, medicine, parenting, and personal relationships.

The Origin of PCM

Dr. Taibi Kahler, a clinical psychologist, discovered how to identify and respond appropriately second by second’ to patterns of productive behaviour (successful communication) and non-productive behaviour (miscommunication).

In 1978, NASA took an interest in Dr Kahler’s research and invited him to use his work to recruit astronauts and assemble operative crews that could successfully cooperate in the very stressful environment of outer space. This was the basis of what was to become the Process Communication Model which has been used extensively in the selection, placement, and training of astronauts.

Today, tens of thousands of people, from astronauts to entrepreneurs to private individuals, have put it to work for themselves. The PCM model is known and recognized throughout the world as a communication and management tool of excellence. As a result of his pioneering work, dr. Kahler received the 1977 Eric Berne Memorial Scientific Award.

Personality structure

Individual personalities are complex. PCM offers a comprehensive approach to help in identifying personality differences and thus in adapting to them for effective interaction. The differences are based on observable and measurable behavioral clues.

The PCM condominium

The metaphor chosen to represent a given personality is that of a 6 floor building or (as it is called in the US) a 6 floor condominium. The model talks about a person’s personality structure as an unique combination of 6 different sets of identifiable behaviours.

Just 6 behavioural types

The “personality structure” of each person is comprised of six, separate and mutually exclusive behaviour types, that have been labelled Thinker, Harmoniser, Persister, Rebel, Imaginer, and Promoter.

Thus represented as a six-floored condominium, the personality structure is ordered, indicating the relative amount of time a person experiences and demonstrates the behaviours of a given type floor.

These second-by-second behaviours – categorized by words, tones, gestures, postures and facial expressions – can be observed objectively with significantly high interjudge reliability. Additionally, test-retest reliability research indicates that once a person’s condominium order is set, that order seldom changes.

Personality Pattern Inventory (PPI)

People who wish to use the Process Communication Model® will first complete the Personality Pattern Inventory (PPI), a questionnaire which, once processed, will enable them to discover their personality structure. The teaching metaphor of a condominium (I.e., a six floor apartment building) helps us to visualise the composition of each unique personality structure.

The Personality Pattern Inventory, also measures the amount of energy available to the individual to experience each personality floor. Correlations for each personality type include: character strengths, management styles, channels of communication, perceptual preferences, environmental choices, and personality traits.

No one type is better or worse, more or less intelligent, or more or less OK. Each has strengths and weaknesses.

Personality Types

In PCM we differentiate 6 different personality types:


Compassionate, sensitive & warm



Organized, responsible & logical



Dedicated, observant, conscientious



Calm, imaginative & reflective



Adaptable, persuasive & charming



Spontaneous, creative & playful

Personality types overview

Each of us has the need to appreciate values like the Persister; has some of the spontaneity of the Rebel; has the compassion and warmth of a Harmoniser; has the ability to be logical as does a Thinker; can enjoy the experience of taking a risk as can a Promoter and has some of the calm and imagination that the Imaginer shows.

In PCM we do not therefore, speak of types of people, but types in people. However we each have one or sometimes two personality types more obvious in us than others.


The base Harmoniser personality character strengths are:

  • Compassionate
  • Sensitive
  • Warm

If you have a Harmoniser base:

  • To stimulate your attention and interest, the person talking with you will use a warm and nurturing voice. You naturally communicate with this nurturative channel.
  • To feel good and be efficient, you require being recognized as a person, i.e. wants to hear “I care about you”, “you’re important to me”. You desire unconditional acceptance of your person and need an environment that pampers the senses.
  • Under light distress, in an interaction with others, you become unassertive regarding what you do, think, or say, and give priority to the other. You may accept unpleasant situations or make “wishy-washy” decisions.
  • Under severe distress, you make mistakes, laugh at yourself or act “stupid”, attracting hostility from others as a consequence.

If your base personality type is Harmoniser, then you are probably appreciated for:

  • Your warmth in relationship, your ability to nurture, be empathic, create harmony and give to others.
  • Your ability to feel first and take in people and things by feeling about them.
  • Your sensory application and your ability to use your five senses.

The base Thinker personality character strengths are:

  • Organized
  • Responsible
  • Logical

If you have a Thinker base:

  • To gain your attention and your interest, the person talking to you will use a factual way of communication asking for or providing data.
  • You and others will communicate better through questions and exchanges of information.
  • To feel good and be efficient, you require being recognized for your thoughts and accomplishments. “Good work.” “Great idea.” “A job well done.” You also require time structure and like to plan things.
  • Under light distress, in interactions with others, you may want to demonstrate you are doing things perfectly and you may reverse delegate. You may also give too many details, and insert needless qualifications, thinking you make yourself seem clearer. If distress increases, you could become overcontrolling, attack others, and argue about time, money, order, or cleanliness.
  • You require return to your logical and structured way of thinking in order to regain your natural efficiency. Reassuring yourself that you are doing a good job, or having others do this, is the key to your recovery.

If your base personality type is Thinker, then you are probably appreciated for:

  • Your capacity for organization and detailed planning.
  • Your logic in structuring ideas or issues and explaining quickly and clearly to others.
  • Your ability to take responsibility, making you a welcome person in both your professional and personal relationships.

The base Persister personality character strengths are:

  • Dedicated
  • Observant
  • Conscientious

If you have a Persister base:

  • To stimulate your attention and interest, the person talking to you will communicate better through questions and exchanges of beliefs and values.
  • To feel good and be efficient, you require your convictions/beliefs to be recognized: “I admire you.” “I value your opinion.” “What do you believe we should do?” You also require being recognized for your accomplishments: “Good work.” “Great contribution.” “A job well done.”
  • Under light distress, in an interaction with others, you may focus on what is wrong rather than what is right; then, if distress increases, you might impose your beliefs, be overly suspicious and righteous: “My opinion is the only right one.”
  • You need to regain trust in the person you are talking to in order to regain your natural efficiency.

If your base personality type is Persister, then you are probably appreciated for:

  • Your ability to observe and give opinions, beliefs, judgements,… about situations and persons.
  • Your conscientiousness in both professional and personal life. People often admire your moral conduct and your ethics.
  • Your devotion to causes, a political party, your company, etc. and your tenacity in respecting your ideals, principles and values.

The base Imaginer personality character strengths are:

  • Calm
  • Imaginative
  • Reflective

If you have a Imaginer base:

  • To grab your attention and your interest, the person talking to you will use a clear, unambiguous and direct way of communication.
  • You don’t react overtly. You take time to answer briefly if you are required to.
  • You may require external stimulation to do things and you tend to wait for others to get in contact.
  • To feel good and be efficient, you require your own private time and space for reflection and introspection. You may well “escape” during long meetings or discussions. This gives you the ability to endure difficult situations.
  • Under light distress, in an interaction with another person, you may wait passively, thinking that time will solve the problem. Then, if distress increases, you might withdraw, not finishing the work you have started.
  • You require a time of solitude to regain your natural efficiency.

If your base personality type is Imaginer, then you are probably appreciated for:

  • Your calm, however grave the situation, in which you are able to quietly analyse the different hypothesis or possible solutions.
  • Your ability to reflect and think about humanity. Observing yourself, you don’t judge others too quickly, your imagination for exploring all the hypothesis or possible options.

The base Promoter personality character strengths are:

  • Adaptable
  • Persuasive
  • Charming

If you have a Promoter base:

  • To stimulate your listening and your interest, the person talking to you will use a firm and directive communication style.
  • You appreciate communicating with this directive style.
  • You are particularly efficient faced with challenges, difficult and new things to do.
  • To feel good and be efficient, you require incidence i.e. lots of excitement in a short period of time. You like the high level of energy in these situations.
  • Under distress, in an interaction with others, you may be impatient and see the other as too weak. Then, if distress increases, you could take risks i.e. for your health, personal safety or your business interests. You could become manipulative to reach your goals without due consideration for others, overstep the limits, break the rules.
  • You require a challenge or positive incidence in order to return being positively motivated and natural efficient.

If your base personality type is Promoter, then you are probably appreciated for:

  • Your charm, born from your direct way of communication and your well aimed compliments. Even if you may be considered tactless, you are appreciated as a good and pleasant companion.
  • Your extraordinarily resourcefullness and your ability to get back on your feet after any setback. You will always get moving again.
  • Your ability to adapt to any new situation or environment. You like change and are turned off by routine.

  • To gain your attention and your interest, the person talking to you will use an up and energic style of communication speaking of likes and dislikes.

  • Under light distress, in an interaction with others, you may start to misunderstand and say thinks like “I don’t know”. Things seem boring and complicated to you. If distress increases, you could project responsibility onto the other and be insincere e.g. “If it weren’t for you”.
  • You require to regain contact with the others through, ‘play’, joking or laughing in this way you can regain your natural efficiency.
