Your personality temperament can be an important factor in teamwork.
One rule of thumb that seems to hold true for any good team is that it has a wide variety of different kinds of personalities involved. In order to establish what kind of personalities should be in a team, management will often administer a so-called personality temperament indicator (PTI) test. These tests are rather like IQ tests, but they gauge a person's individual personality traits, rather than intellectual power.
PTI tests are not tests that have correct answers. Every answer is correct. These tests are meant to help identify the kinds of tasks that you have a natural tendency to do. The idea is that if you like or enjoy to do something, you will likely do it better. So PTI tests are only intended to find the things that you are good at by virtue of your natural abilities and tendencies.
There are various sorts of PTIs available. Perhaps the most popular one is the Myers-Briggs Type Indicator (MBTI), which measures a person's temperament along four different axes: extroversion (E) versus introversion (I), intuition (N) versus sensing (S), thinking (T) versus feeling (F), and judging (J) versus perceiving (P). A personality temperament is some combination of these temperaments.
Note that MBTI style tests build upon so called Jungian personality tests.
A PTI consists of a series of questions, which the applicant answers. Each question measures one temperament. The test is scored by counting up the answers to the questions for each temperament. If, for example, one answers more of the E questions in the affirmative than I questions, then a person is characterized as an extrovert rather than an introvert.
A personality temperament is, then, denoted by a sequence of four letters – for example, ENTJ, denoting an intuitive introvert prefers to make decisions based on rational arguments and to get things done as soon as possible rather than waiting for more information.
Given a group of people with known personality temperaments, one can then begin to group them according to various criteria.
