In order to produce high-quality products, companies have to engage in a variety of activities, one of which is overseeing every stage of the production process which involves the use of some Statistical Process Control (SPC) techniques, with the aim of locating weaknesses and optimizing outcomes. To reduce operating expenses in production, a corporation must implement quality control through careful monitoring and exacting standards to ensure that the production activity fulfills its objectives efficiently. An effective quality control regime will help the manufacturing workflow proceed without unnecessary disruptions. Hence, this research investigates the application of control chart (P-chart) in monitoring and managing the cutting process during metal sheets designs in God's time engineering LTD, Benin City.. The study aims to establish control limits and identify potential sources of variation in key
parameters like edge quality and Surface finish. By implementing control charts (P-Chart), this research seeks to improve the consistency and reliability of God's time engineering metal sheets design and cutting process, ensuring product quality and minimizing defects. By constructing the P-Chart, this study aims to establish control limits, detect deviations from the desired process parameters, and ultimately enhance the overall quality control system for God's time engineering metal sheets design and cutting process. The findings of this research will provide valuable insights for optimizing the production process, reducing waste (offcuts), and maintaining high standards of product quality

Companies must carry out various businesses, one of which is by supervising each production process in order to produce quality products. Quality control is required within a company to minimize operational costs in products. Good quality control will assist in the fluency of the production process, so that the production activity will reach its target. Companies will find means to implement a quality control system that is capable and reliable. One of the methods is using Statistical Process Control (SPC). The case studied in this project was the bottled palm wine product in NIFOR palm wine bottling unit. This research is centered on the quality of nifor bottled palm wine due to breakages during pasteurization. The SPC used is the Control chart (p chart). Based on the analysis of control chart, it is indicated that the process is in control. This can be seen in the control charts where there is the absence of outliers. In the month of January, February, March and April, there are zero out of bounds. Thus the Enterprise can take to maintain and monitor current processes by regular quality checks and statistical monitoring to ensure that the process remains in control.
