There are trends in the use of teams in the classroom that stimulate both theory development and pedagogical innovation in this important area. In particular, three classroom applications are (1) building group process skills, (2) developing team leaders, and (3) using teams to learn course content. Of particular interest are new possibilities for utilizing leadered rather than leaderless groups, systematizing team coaching interventions, and enriching team-based learning. In this field of study, it is clear that pedagogical innovation and theoretical development interact to enhance student learning. Continued exploration in both aspects is encouraged.

A strategic group is defined as a set of firms within an industry pursuing a similar strategy. The strategic group concept emerged with much promise over 40 years ago. Research on strategic groups over time in a broad variety of settings has sought to clarify their theoretical and empirical properties. These research findings are gradually being translated into practical managerial guidance, so that the strategic group concept can be understood, operationalized, and used productively by managers. Two main approaches exist for identifying strategic groups—a ground-up approach, using disaggregated data, and a top-down, using cognition. Once identified, managerial insights can be derived from clarifying a strategic group’s profile. Firm membership in a group helps to uncover immediate and more distant types of competitors. Group profitability differences reveal the more rewarding and less attractive areas within an industry, as well as identify the lower-return groups from where firm exits are likely to occur. Group dynamics reflect competitive and cooperative behavior within and between groups. Several promising areas for future research on strategic groups to improve understanding and practice of strategy.

Group faultlines are hypothetical dividing lines that may split a group into subgroups based on one or more attributes. An example of a strong faultline is a group of two young female Asians and two senior male Caucasians. Members’ alignment of age, sex, and ethnicity facilitates the formation of two homogeneous subgroups. On the other hand, when a group consists of a young female Asian, a young male Caucasian, a senior female Caucasian, and a senior male Asian, the group faultline is considered weak because subgroups, regardless of how they are formed, are diverse. As a relatively new form of group compositional pattern, the group faultline is associated with subgroup formation, and these subgroups, rather than the whole group, can easily become the focus of attention. When members strive to obtain more resources and protect their subgroups, between-subgroup conflict, behavioral disintegration, lack of trust, lack of willingness to share information, and communication challenges are likely. As a result, group performance is often negatively affected, and sometimes groups may even be dissolved. These results were repeatedly found in studies of experimental groups, ad-hoc project groups, organizational teams, top management teams, global virtual teams, family businesses, international joint ventures, and strategic alliances.

Business groups are an organizational model in which collections of legally independent firms bounded together with formal and informal ties use collaborative arrangements to enhance their collective welfare. Among the different varieties of business groups, diversified business groups that exhibit unrelated product diversification under central control, and often containing chains of publicly listed firms, are the most-studied type in the management literature. The reason is that they challenge two traditionally held assumptions. First, broad and especially unrelated diversification have a negative impact on performance, and thus business groups should focus on a narrow scope of related businesses. Second, such diversification is only sustainable in emerging economies in which market and institutional underdevelopment are more common and where business groups can provide a solution to such imperfections. However, a historical perspective indicates that diversified business groups are a long-lived organizational model and are present in emerging and advanced economies, illustrating how business groups adapt to different market and institutional settings. This evolutionary approach also highlights the importance of going beyond diversification when studying business groups and redirecting studies toward the evolution of the group structure, their internal administrative mechanisms, and other strategic actions beyond diversification such as internationalization.
In such a complex and well-researched domain as decision support systems (DSS), with a long history of authors making insightful contributions since the 1960’s, it is critical for researchers, especially those less experienced, to have a broad knowledge of the seminal work that has been carried out by prior generations of researchers. This can serve to avoid proposing research questions which have been considered many times before, without having consideration for the answers which have been put forward by previous scholars, thereby reinventing the wheel or “rediscovering” findings about the life of organizations that have been presented long before. The study of human and managerial decision-making is also characterized by considerable depth and seminal research going back to the beginning of the 20th century, across a variety of fields of research including psychology, social psychology, sociology or indeed operations research. Inasmuch as decision-making and decision support are inextricably linked, it is essential for researchers in DSS to be very familiar with both stream of research in their full diversity so they are able to understand both what activity is being supported and how to analyze requirements for developing decision support artefacts. In addition, whilst the area of decision support has sometimes been characterized by technology-based hype, it is critical to recognize that only a clear focus on the thinking and actions of managers can provide decisive directions for research on their decision support needs. In this article, we consider first the characteristics of human cognition, before concentrating on the decision-making needs of managers and the lessons that can be derived for the development of DSS.
