In my research I will be examining the possible connections between the MyersBriggs Type Indicator (MBTI) - and the Belbin Team Roles surveys. The tools of measurement used in this research can also be utilized during the recruitment process. I believe these surveys can be used for the development of one’s self-knowledge, which nowadays is not a negligible process, due to the fact that the real value of human resources lies in the uniqueness of one’s personality, and the ability to cooperate, in addition to professional knowledge. Firstly, I will present the MBTI’s dimensions, preferences, and the most significant characteristics of each preference. I will mention the differences between the preferences, and highlight the possible interpersonal conflicts that can be caused by dissimilarity among these preferences. After that, I will analyze the characteristics and operation of teams and put significant emphasis on the characteristics of an effective team, and the process of team building. Thereafter, I examine the Belbin Team Roles in more detail. The purpose of my study is to find connections between the two aforementioned tools, and to use these connections to develop the process of self-knowledge and mutual understanding. I believe that the causes of several interpersonal conflicts are the differences and dissimilarities among team roles and personality types, and that is why we should be paying closer attention to them. In addition to this, the recruitment process can also be faster and more efficient with the knowledge and use of these tools. Moreover, it can also be useful when it comes to teamwork, because it can provide help for team members in understanding and accepting each other, thus helping the performance and effectiveness of the mutual work. The fundamental question of my research is to find out which personality types can belong to each team role, and which team role – personality pair is the most common. The hypotheses assign each personality preference to the team roles which suit them the most, based on my assumption. I stated all together five hypotheses which are either qualified or refuted by my research. The method of the research is quantitative, made by questionnaire. Time of the research: September – October, 2015. Made on online site. The sample size is greater than 100 people.
