Translating Member Ability Into Group Brainstorming Performance: The Role of Collective Intelligence

In investigating how member ability is translated into group brainstorming performance, it was predicted that a group’s collective intelligence (CI) would enable it to capitalize on member ability while maximizing process gains and mitigating process losses. Ninety-nine groups were randomly assigned to complete a short brainstorming task using a hybrid (individual-group work) or collective (only group work) task structure. High CI groups were better than low CI groups at translating member ability into group brainstorming performance. Additionally, this hybrid structure was more beneficial for low CI groups than for high CI groups in generating total ideas.

Kaizen event process quality: towards a phase-based understanding of high-quality group problem-solving

Purpose

As a problem-solving tool, the kaizen event (KE) is underutilised in practice. Assuming this is due to a lack of group process quality during those events, the authors aimed to grasp what is needed during high-quality KE meetings. Guided by the phased approach for structured problem-solving, the authors built and explored a measure for enriching future KE research.

Design/methodology/approach

Six phases were used to code all verbal contributions (N = 5,442) in 21 diverse, videotaped KE meetings. Resembling state space grids, the authors visualised the course of each meeting with line graphs which were shown to ten individual kaizen experts as well as to the filmed kaizen groups.

Findings

From their reactions to the graphs the authors extracted high-quality KE process characteristics. At the end of each phase, that should be enacted sequentially, explicit group consensus appeared to be crucial. Some of the groups spent too little time on a group-shared understanding of the problem and its root causes. Surprisingly, the mixed-methods data suggested that small and infrequent deviations (“jumps”) to another phase might be necessary for a high-quality process. According to the newly developed quantitative process measure, when groups often jump from one phase to a distant, previous or next phase, this relates to low KE process quality.

Originality/value

A refined conceptual model and research agenda are offered for generating better solutions during KEs, and the authors urge examinations of the effects of well-crafted KE training.
