Chapter 10, Problem 6P
Gretchen’s Kitchen is a fast-food restaurant located in an ideal spot near the local high school. Gretchen Lowe must prepare an annual staffing plan. The only menu items are hamburgers, chili, soft drinks, shakes, and French fries. A sample of 1,000 customers taken at random revealed that they purchased 2,100 hamburgers, 200 pints of chili, 1,000 soft drinks and shakes, and 1,000 bags of French fries. Thus, for purposes of estimating staffing requirements, Lowe assumes that each customer purchases 2.1 hamburgers, 0.2 pint of chili, 1 soft drink or shake, and 1 bag of French fries. Each hamburger requires 4 minutes of labor, a pint of chili requires 3 minutes, and a soft drink or shake and a bag of fries each take 2 minutes of labor.
The restaurant currently has 10 part-time employees who work 80 hours a month on staggered shifts. Wages are $400 per month for regular time amid $7.50 per hour for overtime. Hiring amid training costs are $250 new employee, and layoff costs are $50 per employee.
Lowe realizes that building up seasonal inventories of hamburgers (or any of the products) would not be wise because of shelf-life considerations. Also, any demand not satisfied is a lost sale amid must be avoided. Three strategies come to mind.
- Use a level strategy relying on overtime and under time, with up to 20 percent of regular-time capacity on overtime.
- Maintain a base of 10 employees, hiring and laying off as needed to avoid any overtime.
- Utilize a chase strategy, hiring and laying off employees as demand changes to avoid overtime.
When performing her calculations, Lowe always rounds to the next highest integer for the number of employees. She also follows a policy of not using an employee more than 80 hours per month, except when overtime is needed. The projected demand by month (number of customers) for next year is as follows:
- Develop the
schedule of service requirements (hours per month) for the next year. - Which strategy is most effective?
- Suppose that an arrangement with the high school enables the manager to identify good prospective employees without having to advertise in the local newspaper. This source reduces the hiring cost to $50, which is mainly the cost of charred hamburgers during training. If cost is her only concern, will this method of hiring change Gretchen Lowe’s strategy? Considering other objectives that may be appropriate, do you think she should change strategies?

Tax Prep Advisers, Inc., has forecasted the following staffingrequirements for tax preparation associates over the next12 months. Management would like three alternative staffingplans to be developed. The company currently has 10 associates. No more than 10new hires can be accommodated in any month because oflimited training facilities. No backorders are allowed, andovertime cannot exceed 25 percent of regular-time capacityon any month. There is no cost for unused overtime capac-ity. Regular-time wages are $1,500 per month, and overtimewages are 150 percent of regular-time wages. Undertime ispaid at the same rate as regular time. The hiring cost is $2,500per person, and the layoff cost is $2.000 per person.a. Prepare a staffing plan utilizing a level workforce strategy,minimizing undertime. The plan may call for a one-timeadjustment of the workforce before month 1.b. Using a chase strategy, prepare a plan that is consistent withthe constraint on hiring and minimizes use of overtime.c.…

She is never involved in any problem-solving activities because the system dictates they must defer to man- agers when problems arise. In addition, she has never been asked to provide any input at the store level of the organization. Her manager tells her what to do and micro-manages her work. Daily information, sche- dules, and work methods changes (e.g., when new menu items are introduced) are posted on notes in a break room bulletin board. Carla isn't very happy in her job and is thinking of quitting to find something else. She has seen about half of her coworkers quit in the last year. Discussion Questions 1. High attrition rates in the QSR industry may be attributed to low levels of employee engagement within the organization. How does high turnover impact product quality and customer service in the QSR industry, as well as the costs to the organization? 2. How can Carla's manager or…arrow_forward
- Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by % in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only thing to be changed. The bakery currently makes loaves per month. The pay will be $ per hour for employees and each employee works 160 hours per month.Charles Lackey can also improve the yield by purchasing a new blender.
