Bayfield Mud Company Essay

1. As Wet-Land Drilling, Inc. had filed a complaint that the bags it received from Bayfield were short-weight by about 5%, they had to determine the cause of the discrepancy. They discovered through checking 50 of the bags that they only had an medium net weight of 47.51 pounds. In order to identify the errors that had occurred in the operation, and why the weight has become inconsistent, Bayfields quality managers may consider development Statistical Process Control (SPC).As mentioned, past shipments had bags that averaged at 50 pounds, which will be the desired mean, X=50, and that had an acceptable standard difference of opinion of 1.2, which will be the desired = 1.2.x = n=1.26=0.4899At a confidence interval of 99.7%, z = 3UCL= x+ 3x=50+3 x 0.4899=51.4697LCL= x 3x=50-3 x 0.4899=48.5303Percentage of Bags with Average Weight within Control Limits (Per trade) Day Shift = 23 bags/24 bags = 96%Afternoon/Evening Shift = 12 bags/24 bags = 50%Night Shift = 12 bags/ 24 bags = 50%2. A s Bayfield had decided to add unsanded alternates due to increased demand, the staccato decision had caused inefficiencies when it came to making sure that the weights of the bags be as close to 50 pounds as possible. While the most experienced foremen were assigned to supervise the new employees of the night shift, they failed to run into sure that the double-checking of the weight of the bags be as unblemished as possible, as they only occasionally reminded the employees of this procedure.The management of Bayfield must make sure that stricter supervising of the double-checking of the bag weight-feeder must be implemented, such as havingscheduled checks (e.g. before the morning shift every day). They also eat up to remind employees that lighter-weight bags cause more than just a weighing problem, as they might result in poor chemical control during the oil production operation and might adversely affect drilling efficiency. Also, among the 25 samples that are considered as above UCL and below LCL, 23 of these are light-weight bags therefore, the weight-feeder must be adjusted as needed, to prevent its frequent production of lighter-weight bags.As it sack up clearly be seen that much of the inefficiencies occur during the afternoon/evening shift and the night shift, Bayfields managers must also consider conducting additional training, specially for the new employees.
