Using the card during the development process:

In the development process, the client identifies the topic, the concrete goal. The development specialist introduces the model of MBTI personality typology in the framework of the reality check for a purpose to develop the self-knowledge.
The model is suitable for assessing the client's preferred thinking, decision-making and problem-solving style, identifying the strengths and potential risks to achieve the goals.

The model:

The Myers-Briggs Type Indicator (MBTI) is an introspective self-report questionnaire designed to indicate psychological preferences in how people perceive the world and make decisions.
The MBTI was constructed by Katherine Cook Briggs and her daughter Isabel Briggs Myers. It is based on the typological theory proposed by Carl Jung who had speculated that there are four principal psychological functions by which humans experience the world -sensation, intuition, feeling and thinking- and that one of these four functions is dominant for a person most of the time.
The underlying assumption of the MBTI is that we all have specific preferences in the way we construe our experiences, and these preferences underlie our interests, needs, values and motivation.
