In the manufacturing process, sterile liquid drug is poured into glass syringes and sealed with a rubber stopper. The remaining stage involves insertion of the cartridge into plastic syringes and the electrical \"tacking\" of the containment cap at a precisely determined length of the syringe. A cap that is tacked at a shorterthandesired length (less than 4.9213 inches] leads to pressure on the cartridge stopper and, hence, partial or complete activation of the syringe. Such syringes must then he scrapped. If the cap is tacked at a longerthandesired length (4.983 inches or longer), the taclc'lng is incomplete or inadequate, which can lead to cap loss and a potential cartridge loss in shipment and handling. Such syringes can be reworked manually to attach the cap at a lower position. However, this process requires a 1U% inspection of the tacked syringes and results in increased cost for the items. This final production step seemed to he producing more and more scrap and reworked syringes over successive weeks. The Excel file Syringe Samples provides samples taken every 15 minutes from the manufacturing process. Develop control limits using the data and use statistical thinking ideas to draw conclusions
