Inquiry into the Effectiveness of Eight Discipline-Based Problem-Solving

Abstract

Purpose: The eight discipline (8D) report is a method for solving problems in industry and is based on an eight-step problem-solving process and is often called an 8D report. The 8D report has been covered in the literature; however, much of the literature on 8D reports only describes the use of 8D reports and fails to evaluate 8D reports empirically. The purpose of this research is to determine if the use of 8D reports combined with training within an organization leads to finding root causes more quickly. Methodology/Approach: The research uses a mixed-methods approach. A case study describes the implementation of 8D reports in a manufacturing organization in the automotive industry. The paper then looks at five years’ worth of data after the implementation of an 8D-based process for addressing quality problems and determined if there is a significant difference in the time to find root causes after the implementation of 8D reports combined with training. Findings: The research found that the time to solve problems was reduced between the early and later years after the implementation of an 8D process and related training. Faster problem resolution means resources can be redirected elsewhere, as well as a reduction in scrap or rework. Research Limitation/Implication: The paper only looked at the use of 8D reports in the case study organization. Originality/Value of paper: This paper provides evidence supporting the effectiveness of 8D reports as an approach to problem-solving. The case study aspect also provides guidance for managers seeking to implement 8D reports in their organizations.
