Meetings are crucial elements in the functioning of organizations. Actors commonly noted as causing a meeting to lose its effectiveness (achieve the desired outcomes) are too many or too few individuals, wrong individuals, lack of goals, and hidden agenda/motives. Several researchers have focused on determining the optimal group size for a meeting. Much of this work was based on the concept that as the size of a group increases, meeting outcome measures (net value) increase until a maximum point is reached. Any further increases in group size would yield negative net benefits. Using induced-value experimentation, we completed controlled experimentation of the relationships between group size and group meeting outcomes. Outcome measures are directly observable rather than being selfreported. We find that no significant differences exist between group size and decision quality or decision satisfaction. There are significant differences across group sizes in solution time, total participation, and average participation. The results raise questions about optimal group size results cited in earlier studies.
Presents results of a study on evaluating the efficiency‐effectiveness relationship of quality circles (QCs). Defines QCs as a means by which organizational goals can be achieved. States that prior studies have examined QCs in an organizational setting. However, these studies have not provided an approach to relate effectiveness and efficiency of QCs at the same time. Extends the body of literature on QCs by presenting an approach management can use to examine the efficiency‐effectiveness relationship of QCs. Uses a data envelopment analysis (DEA) approach and computer‐generated data to illustrate the means by which QCs can be evaluated. Notes that DEA is a linear programming‐ (LP) based method. Provides an approach for visualizing the efficiency‐effectiveness relationship of QCs. Uses the LP model output to gain insight into the ways to improve performance of QCs and notes that the LP output could be used by a manager to take the necessary corrective action.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
