However, in relation to team development processes, there is little research and literature on the role of personality in general and the usefulness of MBTI in particular. This article starts with a review of the MBTI and explores the relationship between MBTI profiles and team processes using a sample of 1,630 people working in 156 teams in a Swedish industrial organization. The results show that only a small number of MBTI personality profiles have a significant relationship with team processes. Overall, the composition of teams in terms of MBTI profiles does not seem to predict team development very well. Findings suggest that the MBTI may be used as an instrument for personal development and as a vehicle for group members to gain a better understanding of each other. http://repub.eur.nl/res/pub/706/ 2000-01-01T00:00:00Z The ongoing skilling debate has already yielded an abundance of contradictory theories, interpretations and empirical contradictions. Based on previous qualitative research in the Netherlands (1992), we have contributed to this debate by introducing the internal differentiation hypothesis. This paper addresses the empirical validity of this hypothesis by analysing data from a representative Dutch panel of 1022 respondents in paid employment. The data show a small overall net upgrading trend. However, automation seems to have different effects for various occupational groups. For blue-collar workers, our findings suggest that a trend of internal differentiation does exist. Next, we examine the consequences (for underemployment and jobsatisfaction) of automation and changes in work content. Although our outcomes do not support our internal differentiation hypothesis, they do show the important effect of autonomy and complexity on feelings of underemployment. The outcomes justify Mottaz? statement that one of the consequences of this underemployment is job dissatisfaction.
