A framework for designing, managing, and improving Kaizen event programs

Purpose: The purpose of this paper is to introduce a framework for the design and management of a Kaizen event program where short-term improvement projects (Kaizen events) are systematically used to introduce rapid change in targeted work areas, often relying on lean work system principles. Design/methodology/approach: To develop the framework and the assessment approach, a comprehensive literature review and a field study of Kaizen event programs in three organizations were conducted. To illustrate the potential usefulness of the framework and the assessment approach, this paper presents a case study of how the framework was applied to design and improve a Kaizen event program in the Belgian Armed Forces. Findings: Use of the framework as a design and assessment tool appeared to make the Kaizen event program more effective in the case study organization. Specific areas of improvement identified included: clearly defining event goals, scheduling extended follow-up activities, defining measures to track results, assigning roles for Kaizen event evaluation activities, and sharing lessons learned in areas of the organization outside the work processes targeted by Kaizen events. Originality/value: With the increased use of lean work system practices in recent years, many organizations are using Kaizen events to rapidly introduce change and to create a culture of continual improvement (or kaizen). However, organizations lack systematic, research-based guidance on how to best design and implement Kaizen event improvement programs and how to best assess results. The proposed framework attempts to address these gaps.
