Statistical process control (SPC) is the correct choice because it utilizes statistical methods to monitor and control a process, ensuring that it operates at its full potential. By analyzing data from the process, SPC helps identify variations that may indicate quality problems, allowing for timely interventions before defects occur. This proactive approach is essential in operations management, as it not only maintains product quality but also enhances overall efficiency.

In comparison, supply chain management focuses more broadly on the entire supply chain's efficiency and effectiveness rather than specifically on quality issues. Tactical planning is related to short-term decision-making and resource allocation, which does not directly address quality control measures. Lastly, while quality control is an important aspect, it often involves aftermath activities to check product quality rather than the ongoing monitoring and proactive prevention that statistical process control provides. Thus, SPC stands out as a dedicated tool for identifying and preventing quality problems through data-driven methods.
