Section 1.2 gives students an overview of quantitative analysis. In this section, a number of qualitative factors, including federal legislation 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 proect planning can be used as e!amples. Teaching Suggestion 1.2: Discussing Other Quantitative Analysis Problems. Section 1.2 covers an application of the quantitative analysis approach. Students can be asked to describe other problems or areas that could benefit ben efit from quantitative analysis. Teaching Suggestion 1.3: Discussing Conflicting Viewpoints. 'ossible problems in the #$ approach are presented in this chapter. $ discussion of conflicting viewpoints within the organi%ation can help students understand this problem. &or e!ample, how many people should staff a registration desk at a university' Students will want more staff to reduce waiting time, while university administrators will want less staff to save money. $ discussion of these types of conflicting viewpoints will help students understand some of the problems of using quantitative analysis. Teaching Suggestion 1.4: Difficulty of etting Input Data. $ maor problem in quantitative quantitative analysis is getting getting proper input data. Students can be asked to e!plain how they would get the information they need to determine inventory ordering or carrying costs.

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. *alculating rates of return, financial ratios from a balance sheet and profit and loss statement, determining the number of units that must be produced in order to break even, and many similar techniques are e!amples of quantitative analysis. #ualitative analysis involves the investigation of factors in a decision)making problem that cannot be quantified or stated in mathematical terms. +he state of the economy, current or pending legislation, perceptions about a potential client, and similar situations reveal the use of qualitative analysis. In most decision)making problems, both quantitative and qualitative analysis are used. In this book, however, we emphasi%e the techniques and approaches of quantitative analysis. scientific approach to managerial decision making. +his type of 1#%$ #uantitative analysis is the scientific analysis is a logical and rational approach to making decisions. motions, guesswork, and whim are not part of the quantitative analysis approach. $ number of organi%ations support the use of the the scie scient ntif ific ic appro approac achh- the the Inst Instit itut utee for for per perat atio ion n (ese (esear arch ch and /anag /anagem ement ent Scie Scienc ncee 0I&(/S, 3ecision Sciences Institute, and $cademy of /anagement. +hee three hree cate catego gori ries es of busi busine nesss anal analyt ytic icss are are desc descri ript ptiive, ve, pred prediicti ctive, ve, and and 1#&. +h prescriptive.3escriptive analytics provides an indication of how things performed in the past.'redictive analytics uses past data to forecast what will happen in the future.'rescriptive analytics uses optimi%ation and other models to present better ways for a company to operate to reach goals and obectives. #uantitativee analysis analysis is a step)by)st step)by)step ep process process that allows decision makers to investigate investigate 1#'$ #uantitativ problems using quantitative techniques. +he steps of the quantitative analysis process include defining the problem, developing a model, acquiring input data, developing a solution, testing the solution, analy%ing the results, and implementing the results. In every case, the analysis begins with defining the problem. +he problem could be too many stockouts, too many bad debts, or determining the products to produce that will result in the ma!imum profit for the organi%ation. $fter the problems have been defined, the ne!t step is to develop one or more models. +hese models could be inventory control models, models that describe the debt situation in the organi%ation, and so on. nce the models have been developed, the ne!t step is to acquire input data. In the inventory problem, for e!ample, such factors as the annual demand, the ordering cost, and the carrying cost would be input data that are used by the model developed in the preceding step. In determining the products to produce in order to ma!imi%e profits, the input data could be such things as the profitability for all the different products, the amount of time that is available at the various production departments that produce the products, and the amount of time it takes for each product to be produced in each production department. +he ne!t step is developing developing the solution. solution. +his requires manipulation manipulation of the model in order to determine determine the best soluti solution. on. e!t, e!t, the result resultss are tested tested,, analy%ed analy%ed,, and implem implement ented. ed. In the invento inventory ry control control problem, this might result in determining and implementing a policy to order a certain amount of inventory at specified intervals. &or the problem of determining the best products to produce, this might mean testing, analy%ing, and implementing a decision to produce a certain quantity of given products.

In this book, mathematical models are used to describe mathematical relationships in solving quantitative problems. In this question, the student is asked to develop two mathematical models. +he student might develop a number of models that relate to finance, marketing, accounting, statistics, or other fields. +he purpose of this part of the question is to have the student develop a mathematical relationship between variables with which wh ich the student is familiar. familiar. interviews with employees and 1#*$ Input data can come from company reports and documents, interviews other personnel, direct measurement, and sampling procedures. &or many problems, a number of different sources are required to obtain data, and in some cases it is necessary to obtain the same data from different sources in order to check the accuracy and consistency of the input data.
