Final answer:
Johnny should consider introducing a quality assurance system to address the increase in faulty product returns and improve the overall product quality.
Step-by-step explanation:
Johnny should consider introducing a quality assurance system. The increase in faulty product returns could be addressed through a quality assurance system, as it focuses on preventing issues before they occur rather than simply fixing them after the fact. By implementing quality assurance measures, such as comprehensive testing and inspections throughout the production process, the company can identify and resolve potential quality problems early on, improving the overall product quality and reducing the number of faulty products.
Furthermore, the company's rapid growth and expansion may have contributed to the quality issues. Introducing a quality assurance system can help address these issues by ensuring that the production process is properly organized and efficient, even with the increased scale of production. It can also provide a framework for the company to effectively manage the new suppliers and staff that have been brought on during the expansion.
Overall, by implementing a quality assurance system, Johnny can proactively address the recent increase in faulty product returns, improve product quality, and ensure that the company's growth is properly managed.
