Critical Thinking

The global marketplace has witnessed an increased pressure from customers and competitors in manufacturing as well as service sector (Basu, 2001; George, 2002). Due to the rapidly changing global marketplace only those companies will be able to survive that will deliver products of good quality at cheaper rate and to achieve their goal companies try to improve performance by focusing on cost cutting, increasing productivity levels, quality and guaranteeing deliveries in order to satisfy customers (Raouf, 1994).

Increased global competition leads the industry to increasing efficiency by means of economies of scale and internal specialization so as to meet market conditions in terms of flexibility, delivery performance and quality (Yamashina, 1995). The changes in the present competitive business environment are characterized by profound competition on the supply side and keen indecisive in customer requirements on the demand side. These changes have left their distinctive marks on the different aspect of the manufacturing organizations (Gomes et al., 2006). With this increasing global economy, cost effective manufacturing has become a requirement to remain competitive.

To meet all the challenges organizations try to introduce different manufacturing and supply techniques. Management of organizations devotes its efforts to reduce the manufacturing costs and to improve the quality of product. To achieve this goal, different manufacturing and supply techniques have been employed. The last quarter of the 20th century witnessed the adoption of world-class, lean and integrated manufacturing strategies that have drastically changed the way manufacturing firm’s leads to improvement of manufacturing performance (Fullerton and McWatters, 2002).

1 Frito-Lay’s Quality-Controlled Potato ChipsFrito-Lay’s Quality-Controlled Potato Chips Frito-Lay, the multi-billion-dollar snack food giant, produces billions of pounds of product every year at its dozens of U.S. and Canadian plants. From the farming of potatoes—in Florida, North Carolina, and Michigan—to factory and to retail stores, the ingredients and final product of Lay’s chips, for example, are inspected at least 11 times: in the field, before unloading at the plant, after washing and peeling, at the sizing station, at the fryer, after seasoning, when bagged (for weight), at carton filling, in the warehouse, and as they are placed on the store shelf by Frito- Lay personnel. Similar inspections take place for its other famous products, including Cheetos, Fritos, Ruffles, and Tostitos. In addition to these employee inspections, the firm uses proprietary vision systems to look for defective potato chips. Chips are pulled off the high-speed line and checked twice if the vision system senses them to be too brown. The company follows the very strict standards of the American Institute of Baking (AIB), standards that are much tougher than those of the U.S. Food and Drug Administration. Two unannounced AIB site visits per year keep Frito-Lay’s plants on their toes. Scores, consistently in the “excellent” range, are posted, and every employee knows exactly how the plant is doing. There are two key metrics in Frito-Lay’s continuous improvement quality program: (1) total customer complaints (measured on a complaint per million bag basis) and (2) hourly or daily statistical process control scores (for oil, moisture, seasoning, and salt content, for chip thickness, for fryer temperature, and for weight). In the Florida plant, Angela McCormack, who holds engineering and MBA degrees, oversees a 15-member quality assurance staff. They watch all aspects of quality, including training employees on the factory floor, monitoring automated processing equipment, and developing and updating statistical process control (SPC) charts. The upper and lower control limits for one checkpoint, salt content in Lay’s chips, are 2.22% and 1.98%, respectively. To see exactly how these limits are created using SPC, watch the video that accompanies this case.

Discussion Questions* 1.Angela is now going to evaluate a new salt process delivery system and wants to know if the upper and lower control limits at 3 standard deviations for the new system will meet the upper and lower control specifications noted earlier.

She picks a sample of four each hour for 5 hours. The data (in percent) from the initial trial samples are:

Sample 1: 1.99, 2.0, 2.08, 1.99

Sample 2: 1.98, 2.11, 2.15, 2.06

Sample 3: 2.01, 2.08, 2.14, 2.16

Sample 4: 2.18, 2.01, 2.23, 1.98

Sample 5: 2.20, 2.10. 2.20, 2.05

Analyze the data and draw the 푿푿� and R control charts in Microsoft Excel including the upper and lower control limits. (Hint: There is no population standard deviation available so you need to get A2, D3 and D4 for upper and lower limits)

2.Given these data and your analysis, what conclusion do you, as a Frito Lays quality control inspector, draw from this process? What report do you issue to your supervisor Angela? Explain your findings and decision based on the data analysis. (Hint: by monitoring the performance in these five hours, what will happen in the following hours as you observe from here?)

3.What are the advantages and disadvantages of Frito-Lay drivers stocking their customers’ shelves? Remark: Answer Question 1 in Excel File and Question 2 and 3 in Word file

The total plan for the project involved 1000 staff-days of value (the Budgeted at Completion or BAC) accumulated over 10 months with a staff of 5 full-time people. At the 4-month mark, with no open tasks, the total accumulated earned value is 320 staff-days. The plan at this point is for 340 staff-days to have been earned. Alas, the actual amount spent (because extra staff time has already been spent on this project) is 370 staff-days.
A summary of the facts:
1. Original project cost: 1000 staff-days
2. Original project schedule: 10 months
3. Planned value: 340 staff-days at 4 months
4. Actual cost: 370 staff-days
5. Earned value: 320 staff-days
6. Current monthly staff: 5 people

5. What is the projected total cost Estimate at Completion (EAC)?
a. If we assume cost variance was atypical (and the rest of the project will go as originally planned)?
b. If we assume cost variance was typical (and the rest of the project will have a proportional variance)?
c. If we assume we can re-plan the remaining project and make a whole new estimate?
6. What is the projected schedule Estimate at Completion (EAC)?
a. If we assume schedule variance was atypical (and the rest of the project will be as originally planned)?
b. If we assume schedule variance was typical (and the rest of the project will have a proportional variance)?
c. If we assume we can re-plan the remaining project and make a whole new estimate?
7. What are the remaining cost-to-complete and schedule-to-complete figures for each of a, b, and c?
8. What is the intensity of work required to finish the work with the available funds? (These funds can be defined as either the original Budget at Completion (BAC) or the current Cost Estimate at Completion (EAC).)

Imagine that you are a systems administrator withing your company that has decided to leverage Azure for resource deployment. You have done research on Azure and learned about Azure Automation and how it can help simplify some of the management and configuration activities you execute on a daily, weekly, and monthly basis. You decide that you want to recommend piloting Azure Automation to show the value, but need to decide on one or two tasks to prove the value of Azure Automation to your manager.  

Thinking about the various management and configuration tasks that happen within an on-premises and/or cloud environment, what one or two tasks would you recommend as candidates for this pilot. Why would your pilot these tasks? Examples of candidate tasks may pertain to security, system maintenance, and/or service configuration at the resource level.
