Abstract

Two approaches to problem solving are the 8D report and the A3 report. Although organizations may use these approaches interchangeably, the 8D report is better suited for problem solving due to root cause analysis (RCA)—such as identifying the specific cause of a scrapped part—and the A3 report is optimal for continuous improvement (CI)—such as finding and eliminating causes of scrap in a process.
