The management of a drinking water refill station is planning to estimate the average cost of paying technicians to maintain the water refill stations. The management wants their OM to provide normal times and standard times for cleaning a station based on observed values, rating factors (RF), and a 20% allowance.
A Methods and Measurements Analyst needs to develop a time standard for a certain task. The task involves use of a ruler, square, and portable electric saw to mark and cut the "notch" in a rafter (a standard carpentry task of home construction). In a preliminary study, he observed one of his workers performing this task five times. The observations were made in an air-conditioned, well-lit training facility, at ground level, with all tools and equipment clean and readily available.
Observation:

Task time (seconds):

a. What is the actual average time for this task?
b. What is the normal time for this task if the employee worked at a 20% faster pace than is typical for adequately trained workers?
c. What is standard time for this task if allowances sum to 14%?
d. If the analyst then thought more carefully about his experiment and decided that the allowances needed to be increased to match the real (outside, not air-conditioned)…
Compare stopwatch time study and work sampling.

- 15-19 A new president at Big State University has made student satisfaction with the enrollment and registration process one of her highest priorities. Students must see an advisor, sign up for classes, obtain a parking permit, pay tuition and fees, and buy textbooks and other supplies. During one registration period, 10 students every hour are sampled and asked about satisfaction with each of these areas. Twelve different groups of students were sampled, and the number in each group who had at least one complaint is as follows: 0, 2, 1, 0, 0, 1, 3, 0, 1, 2, 2, 0. Develop upper and lower control limits (99.7%) for the proportion of students with complaints.arrow_forwardIn recent years more people have been working past the age of 65. In 2005, 27% of people aged 65-69 worked. A recent report from the Organization for Economic Co-operation and Development (OECD) claimed that the percentage working had increased (USA Today, November 16, 2012). The findings reported by the OECD were consistent with taking a sample of 600 people aged 65-69 and finding that 180 of them were working. a. Develop a point estimate of the proportion of people aged 65-69 who are working (to 2 decimals). b. Set up a hypothesis test so that the rejection of Ho will allow you to conclude that the proportion of people aged 65-69 working has increased from 2005.

This upcoming Tuesday will be the 3rd meeting the sales team from La Carva Luxury Bathtubs will be having with a prospect regarding bathtubs she would like to purchase. The sales team conducted a presentation five months ago to a group of prospects, which this prospect attended. While the prospect expresses great interest in the product, at the previous meetings she seems to have additional concerns regarding the bathtubs and was not able to come to a decision to make a purchase. This issue is becoming overwhelming, and the sales team intends to address this matter once and for all. Based on the listening technique in the LAER MODEL, how will this effectively address the prospect's objections? Explain. Please be mindful to use relevant personal selling and marketing concepts to support the claim.arrow_forwardVirginia College promotes a wide variety of executive training courses for firms in the Arlington, Virginia, region.

Steps in the Analysis Identify the Problem: The first step in the cause and effect analysis is to identify the problem. For CoffeeVille, the problem was the increased wait times. Create the Fishbone Diagram: The next step is to create the backbone of the fishbone diagram, which is a straight line drawn from left to right. The problem or effect is written at the head or on the right side of the fishbone. Identify the Major Factors Involved: Next, identify the major factors that could be the causes of the problem. These are drawn as "bones" off the spine. For CoffeeVille, these could include staff, procedures, equipment, and materials. Identify Possible Causes: For each major factor, identify possible causes of the problem. These are the sub-factors or secondary causes…arrow_forwardResearch Scenario: A cola company is testing it's 12 ounce cans to make sure that the machine in filling them correctly.
