This Six Sigma DMAIC project addresses delays in resolving key malfunction defects in Kensington wireless handheld keyboards. The current resolution time averages 15.5 days, exceeding the target of 12.5 days and leading to a 20% drop in customer satisfaction. The DMAIC framework was utilized to identify and address key root causes, including outdated communication methods and insufficient employee training. To resolve these issues, the project implemented a modern communication platform to streamline interdepartmental coordination and introduced comprehensive training programs to enhance employee skills and efficiency. These targeted interventions resulted in a substantial reduction in resolution time, improved process stability, and increased customer satisfaction. By focusing on communication and training, the project highlights the significant impact of operational improvements on organizational performance. The findings demonstrate the effectiveness of Lean Six Sigma principles in delivering measurable business outcomes and emphasize the value of data-driven strategies for achieving long-term operational excellence.
