The Myers–Briggs Type Indicator (MBTI) is a way of classifying people into 16 personality types. The psychological test carried out via a questionnaire that the individual answers alone are designed to help them learn more about themselves, understand their own personalities, how they make decisions, their working preferences and compatibility with other people.

The basis of the theory is that what appears as random variations in behaviour is in fact quite orderly and consistent, due to basic differences in the ways individuals prefer to see the world and make decisions.

Using Myers-Briggs within the workplace provides psychology-based solutions, with research behind it spanning more than 50 years, to common issues within the workplace based on both individual and team levels. Similarities and differences between team members can be identified, allowing teams to improve their working and personal relationships in a positive and constructive way, avoid conflict and become more efficient.

MBTI gives teams a common language to interpret interpersonal differences and is one of the most relied upon psychology-based methods of Team Development.
