The following data was collected for a scooter production line that operates Monday through Friday. Calculate the monthly multifactor productivity for the current month in dollars. List any assumptions necessary for calculations. Full Time Employees (40 hour week) Hourly Wage Monthly Overhead Cost Raw Material Cost per Week Scooters Produced Daily Finished Scooter Cost 5 $22.00 $550.00 $900.00 120 $65.00 Multifactor Productivity ($) = Point out the problem with each of the 4 situations below as they relate to Deming's 14 Points and suggest a way to remedy the situation. Upper management institutes a policy that all staff should remain in their work areas in an effort to increase productivity. They feel too much time is wasted on small talk. The manager for a heat pump service company wants his crews to increase their output by 10% and sends out an email to each crew with their new goal. The methods to achieve the increase are left up to each crew. A vice-president, in from the corporate headquarters, takes a tour of the manufacturing floor. She notices that control charts tracking product dimensions are posted up in common areas in all the workstations. The local plant manager informs her they are for tracking progress in minimizing defects. After the tour, she writes a memo to all line managers to remove the control charts from the production areas so workers won't concentrate on the defects. Mike McGillicutty is the vice-president of manufacturing. His reputation is one for meeting deadlines no matter what the cost which has earned him the knick-name of "Mean Mike" among the production workers. Recently, a large order has come in and Mike has been hounding the leads in the work areas to meet this deadline - or else there will be firings. The time elapsed to install motorcycle gas tanks is measured. Six samples, each consisting of 18 observations have been gathered and analyzed. The results are in the table below. The standard deviation for the overall process is unknown. Sample Mean 1 5.06 2 5.14 3 4.96 4 5.08 5 4.93 6 4.99 Range 0.28 0.43 0.29 0.35 0.39 0.53 a.

An electronics company is testing their batteries. The test reveals whether a battery has voltage in a specified range (pass) or does not (fail). The sample data below shows how many batteries out of each sample failed the test. A sample consists of 50 observations. Determine the control limits for the fraction of defective batteries using three sigma limits. If the process is not in control, eliminate any values outside of the upper control limit and compute revised limits.
