What Makes Teams Work: Group Effectiveness Research from the Shop Floor to the Executive Suite

In this article, we summarize and review the research on teams and groups in organization settings published from January 1990 to April 1996. The article focuses on studies in which the dependent variables are concerned with various dimensions of effectiveness. A heuristic framework illustrating recent trends in the literature depicts team effectiveness as a function of task, group, and organization design factors, environmental factors, internal processes, external processes, and group psychosocial traits. The review discusses four types of teams: work, parallel, project, and management. We review research findings for each type of team organized by the categories in our heuristic framework. The article concludes by comparing the variables studied for the different types of teams, highlighting the progress that has been made, suggesting what still needs to be done, summarizing key leamings from the last six years, and suggesting areas for further research.

A Predictive Model of Self-Managing Work Team Effectiveness

This paper tests a theoretically-driven model of self-managing work team effectiveness. Self-managing work team effectiveness is defined as both high performance and employee quality of work life. Drawing on different theoretical perspectives including work design, self-leadership, sociotechnical, and participative management, four categories of variables are theorized to predict self-managing work team effectiveness: group task design, encouraging supervisor behaviors, group characteristics, and employee involvement context. Data is collected from both a set of self-managing and traditionally managed teams from a large telephone company, and the model is tested with structural equations modeling. Support is found for hypotheses concerning group task design, group characteristics, and employee involvement context, but not encouraging supervisory behaviors.

The Effectiveness of Self-Managing Teams: A Quasi-Experiment

This study used a quasi-experimental design to assess the effectiveness of self-managing teams in a telecommunications company. These teams performed customer service, technical support, administrative support, and managerial functions in a variety of locations. The balance of evidence indicates that self-managing teams were more effective than comparable traditionally-managed groups that performed the same type of work. The study illustrates the value of a collaborative research project in which researchers and clients jointly define the research questions, study design, and methods.

Developing Effective Self-Managing Work Teams in Service Organizations

A large body of research has emerged on the effective implementation of self-managing work teams (SMWTs). However, virtually all of the research has been conducted in manufacturing settings. This article draws upon the authors’research on SMWTs in two service organizations: an insurance operation and a telecommunications company. The authors focused on two research questions: First, they examined the relationships among different dimensions of SMWT effectiveness. Second, the authors explored the key success factors for SMWTs in a service context. They found that the different dimensions of SMWTs’effectiveness do not reinforce one another and are largely unrelated, and that creating an employee involvement (EI) context, work design, and team characteristics were important predictors of SMWT effectiveness. Surprisingly, team leadership was not important for SMWT effectiveness; in fact, sometimes, team leadership was negatively related to effectiveness.

Measuring the Relationship Between Managerial Competencies and Performance

The use of competency systems to evaluate, reward, and promote managers has become commonplace in many organizations in recent years. Yet, despite their popularity, there is little evidence that competency systems increase managerial effectiveness. In this study, we estimate the relationship between managerial competencies and performance at both the individual and organizational unit levels. We find evidence that competencies are positively related to individual-level performance and that individual managerial performance may be increased by mentoring on a competency system. The evidence of a link between competencies and unit-level performance is weaker.

Effects of task interdependence and type of communication on performance in virtual teams

Purpose – To investigate the effects of within‐group task interdependence and the degree of communications synchrony on performance in virtual teams (VT).Design/methodology/approach – A 2 × 2 factorial design of 240 participants in Spain, randomly assigned to 80 three‐person teams, was used. Teams worked virtually (not meeting face‐to‐face), performing a merit‐rating task in a laboratory setting.Findings – The analyses revealed an interaction effect between task interdependence and synchrony of communication. High values of VT performance were found both under conditions of “low task interdependence” and “asynchrony of communication” and under conditions of “high task interdependence” and “synchrony of communication”. The results show that superior VT performance is contingent on the match between the nature of the task and the choice of communications modality.Research limitations/implications – First, additional research will be needed to confirm and extend the findings in actual working environments.

DEVELOPING COMPLEX COLLABORATIONS: BASIC PRINCIPLES TO GUIDE DESIGN AND IMPLEMENTATION

People have worked together since the beginnings of human time. Since then the forms of collaboration have barely changed. While a group of laborers building the pyramids of Egypt might seem to bear little resemblance to a team of machine operators working in a plant, they actually have much in common. Both groups are made up of people of similar backgrounds with clear loyalties and interests, interacting face-to-face to perform relatively well-defined tasks in pursuit of a shared goal.
