1 T EACHING S UGGESTIONS Teaching Suggestion 1.1: Importance of Qualitative Factors. Section 1.2 gives students an overview of quantitative analysis. In this section, a number of qualitative factors, including federal leg- islation and new technology, are discussed. Students can be asked to discuss other qualitative factors that could have an impact on quantitative analysis. Waiting lines and project planning can be used as examples. Teaching Suggestion 1.2: Discussing Other Quantitative Analysis Problems. Section 1.2 covers an application of the quantitative analysis ap- proach. Students can be asked to describe other problems or areas that could beneFt from quantitative analysis. Teaching Suggestion 1.3: Discussing Con±icting Viewpoints. Possible problems in the QA approach are presented in this chap- ter. A discussion of con±icting viewpoints within the organization can help students understand this problem. ²or example, how many people should staff a registration desk at a university? Stu- dents will want more staff to reduce waiting time, while university administrators will want less staff to save money. A discussion of these types of con±icting viewpoints will help students understand some of the problems of using quantitative analysis. Teaching Suggestion 1.4: Dif²culty of Getting Input Data. A major problem in quantitative analysis is getting proper input data. Students can be asked to explain how they would get the in- formation they need to determine inventory ordering or carrying costs. Role-playing with students assuming the parts of the analyst who needs inventory costs and the instructor playing the part of a veteran inventory manager can be fun and interesting. Students quickly learn that getting good data can be the most difFcult part of using quantitative analysis. Teaching Suggestion 1.5: Dealing with Resistance to Change. Resistance to change is discussed in this chapter. Students can be asked to explain how they would introduce a new system or change within the organization. People resisting new approaches can be a major stumbling block to the successful implementation of quantitative analysis. Students can be asked why some people may be afraid of a new inventory control or forecasting system. S OLUTIONS TO D ISCUSSION Q UESTIONS AND P ROBLEMS 1-1. Quantitative analysis involves the use of mathematical equations or relationships in analyzing a particular problem. In most cases, the results of quantitative analysis will be one or more numbers that can be used by managers and decision makers in making better decisions. Calculating rates of return, Fnancial ra- tios from a balance sheet and proFt and loss statement, determin- ing the number of units that must be produced in order to break even, and many similar techniques are examples of quantitative analysis. Qualitative analysis involves the investigation of factors in a decision-making problem that cannot be quantiFed or stated in mathematical terms. The state of the economy, current or pend-
