We have made the book shorter by keeping the most conunonly used content. We also reduced the prefonnaned online content so that the book does not appear too dependent on this content. We reduced the number of references in each chapter.

Specifically, we streamlined the introductorr coverage of business intelligence and u"lta mining by deleting Chapter S and instead putting some of that content in Chapter 1. With this change, the reader can get an overview of the overall content through Chapter lboth decision suppon and BI technologies.

We deleted the chapters that were available as online chap- ters with the last edition and incorporated some of tbat coment into this edition. This edition includes one new author and an expanded role for an author from the last edition.

Building upon the excellent content that has been prepared by the authors of the previous edition Turban, Aronson, Liang, and Sharda , this edition was revised printarily by Ramesh Sharda and Dursun Delen. Both Ramesh and Dursun have worked extensively in DSS and data mining and have industry as well as research experience. Although the figures in the print edition have been retained from previous editions and new figures added for the new content. Adopters of the textbook will have access to a Web site that will include links to news stories, software, tutorials, and even YouTube videos related to topics covered in the book.

Almost all of the chapters have new opening vignenes and closing cases that are based on recent stories and events. For example, the closing case at the end of Chapter 2 asks the students to apply Simon's decision- making phases to bener understand the current economic conditions caused by the subprime mortgage mess in the United States.

In addition. New Web site links have been added throughout the book. We also deleted many older product links and references. Internet assigrunents. Other specific changes made to the ninth edition are sUllJITl. The PC-based version of the software is available for free to academics.

In Part I, we provide an overview of the whole book in one chapter. We cover several topics in this chapter. The first topic is managerial decision making and its computerized support; the second is frameworks for decision support. We then introduce business intelligence. We also provide brief coverage of the tools used and their implementation, as well as a preview of the entire book. Organizations, private and public, are under pressures that force them to respond quickly to changing conditions and to be innovative in the way they operate.

Such activities require organizations to be agile and to make frequent and quick strategic, tactical, and operational Processing these , in the framework of the needed decisions.

This book is about using business intelligence as computerized support for managerial decision making.

It concentrates both on the theoretical and conceptual foundations of decision support , as well as on the conunercial tools and techniques that are available. This chapter has the following sections: Each day. Managers focused on opti- mizing the use of railcars to get the most production out of their fIXed assets. Vice and enter into contracts with customers. On-time delivery became an important factor in the industry. Over time, Norfolk Southern responded 10 these industry changes by becoming a "scheduled railroad.

In this way, managers could predict when they could get a shipment 10 a customer. Norfolk Southern has always used a variety of sophisticated systems to run its business.

Norfolk Southern bas an enterprise data warehouse, which means that once data is placed in the warehouse.

Although train and connection perfonnance data is used for the TOP applic3lion, the company has been able to levemge that dam for all kinds of other purposes. For example, the Marketing Depaltrnenl has developed an application called accessNS, which was built for Norfolk Southern customers who want visibility into Norfolk Southern's eXlensive transponation network. Customers want to know where their shipments are "right now"-and at times they want hiSlorical information: Where did my shipment come from?

The company was also one of the first railroads to provide a large variety of historical dam to external customers. How are information systems used at Norfolk Southern to suppon decision making? What type of information is accessible through the visualization applications? What type of information suppon is provided through accessNS? How does Norfolk Southern use the data warehouse for HR applications? Can the same dam warehouse be used for business intelligence and optimization applications?

Getting more out of a company's assets requires more timely and detailed understanding of its operations. We will see many examples of such applications throughout this book.

In order to understand why computerized support is needed and how it is provided, especially for dedsion-making support, let 's look at managerial decision making. Sectio n 1. The resources are considered inputs, and attainment of goals is viewed as the output of the process.

The degree of success of the organization and the manager is often measured by the ratio of outputs to inputs. This ratio is an indi cation of the organization's productivity, which is a reflection of the orgalliztilional alld gerial performance.

The level of productivity or the success of management depends on the perform- ance of managerial functions , such as planning, organizing, directing, and controlling. To perform their functions , managers are engaged in a continuous process of making dedsions. Making a decision means selecting the best alternative from two or more solutions.

The Nature of Managers' Work Mintzberg's 20Cl8 daSliic study of top managers and several replicated studies suggest that managers perfonn 10 major roles that can be classified into three major categories: To perform these roles. This infomlation is delivered by networks, generally via Web technologies.

In addition to otxaining infomlation necessary to better perfonn their roles, nlan- agers use computers directly to support and improve decision making, which is a key task that is part of most of these roles.

Many managerial activities in all roles revolve around decision making. Mallagers, especially those til bigb managerial levels, are prima- rily decisioll makers. We review the dedsion-making process next but will study it in more detail in the next chapter. The Decision-Making Process For years, managers considered decision making purely an art- a talent acquired over a long period through experience Le.

Management was considered an art because a variety of individual styles could be used in approaching and successfully solving the same types of managerial problems. These styles were often based on creativity, judgment.

However, recent research suggests that companies with top managers who are more focused on persistent work almost dullness tend to outperform those with leaders whose main strengths are interpersonal conununication skills Kaplan et aI. It is more important to emp hasize methodical , thoughtful , analytical decision making rather than flashiness and interpersonal communication skills.

CompilO'd from H. Managers usually make decisions by following a four-step process we learn more about these in Chapter 2: Define the problem j. To follow this process, one must make sure that sufficient alternative solutions are being considered. However, the envirorunenml f: Because of mese trends and changes, it is nearly impossible to rely on a trial-and- error approach to ma.

Managers must be more sophisti cated; they must use the new lools and techniques of their fields. Most of those tools and techniques are discussed in mis book. In the following section. Il rok Why h: Describe the four steps managers take in making a decision. Computer applications have moved from transaction processing and moniloring activ- ities to problem analysis and solution applications, and much of the a. Managers must have high-speed, networked infor- mation wireline or wireless to assist them with their most important b sk: A computer enables the decision maker to perform many cornputMion: Ti,,,e]r decision: With a computer, mousands of alternatives can be evaluated in seconds.

Furthel"more, the benefits--to-cost ratio of computers and the speed of executions are constantly increasing. Many decisions are made today by groups whose members may be in different locations. Groups can collaborate and communicate readily by using Web-based tools.

Collaboration is especially important along the supply chain, where panners--aU the way from vendors to custOfl1CfS--fI1USt share information. Computerized s upport can User name: In addition, computerized support can increase the productivity of staff support e. Decision makers can also increase their productivity by using software optimiZ3tion tools that help determine the best way to run a business see Chapter 4. Many decisions involve complex computa- tions. Data for these can be stored in different databases anywhere in the organ- ization and even possibly at Web sites outside the organizat ion.

The data may include text. It may be necessary to transmit data quickly from distant locations. Computers can search. Large data warehouses, like the one operated by Wal -Malt, contain terabytes and even petabytes of data.

Computers can provide extremely great storage capability for an y type of digital information. Special methods, including parallel computing, are available to organize, search, and mine the data.

The costs related to daL"l warehousing are declining. Computers can improve the quality of decisions made. For example, more daw can be accessed, mOTe alternatives can be evaluated, forecasts can be improved, risk analysis can be perfonned quickly, and the views of expens some of whom are in remote locations can be collected quickly and at a reduced cost. Expertise can even be derived directly from a computer system using anificial intelligence methods discussed in Part III and also Chapter With computers, decision makers can perfornl complex simulations, check many possible scenarios, and assess diverse impacts quickly and economically.

Omlpetition today is based not just cu price but also on quality, timeliness, customiZ3tion of pnxiucts, and customer support. In addition, organizations must be able to frequently and rapidly change their mode of operation, reengineer processes and structures, empower employees, and innOv. Decision support tedmologies such as intelligent systems can empower people by allowing them to make good decisions quickly, even if they lack some knowledge.

According to Simon , the human mind has only a limited ability to process and store infor- mation. People sometimes fmd it difficult to recall and use information in an error-free fashion due to their cognitive limits. The tenn cognitive limits indicates that an indi- vidual"s problem-solving capability is linuted when a wide range of diverse infcnnation and knowledge is required.

Since the development of the Internet and Web servers and tools, there have been dramatic changes in how decision ntakers are supported.

Next, we present an early frame- work for decision suppan. Section 1. How have the capabilities of computing evolved over time? So How can a computer help overcome the cognitive limits of humans? Gorry and Scott-Morton created and u sed this frnmework in the early s, and the framework then evolved into a new technology called DSS. Two dimensions are the degree of structuredness and the types of control. Structured processes are routine and typically repetitive problems for which Slandan!

Unstructured processes are fuzzy, complex problems for which there are no cut-and-dried solution methods. Simon also described the dccislon- making process with II throe-phase process of inrcfllgmu: Later, a fourth phase was added: The four phases are defined as follows: This phase involves selecting 3 course of action from among those av:.

Jtcgorics Problems or Opportunities Implementation Deploy: The initial purpose of this matrix was to suggest different types of computerized suppon to different cells in the matrix.

Human intellect and a different approach to computer technologies are necessary. They proposed the use of a supponive infonna- tion system. Note that the more structured and operational control-oriented tasks such as those in cells I, 2, and 4 are usually performed by lower-level managers, whereas the tasks in cells 6, 8, and 9 are the responsibility of top executives or highly trained specialists.

Computer Support for Structured Decisions Computers have supported structured and some semistructured decisions, especially those that involve operational and managerial control, since the s.

Operational and managerial control decisions are made in all functional areas, especially in finance and production i. Structured problems, which are encountered repeatedly, have a high level of struc- mre. It is therefore possible to abstract. For example, a make-or-buy decision is one category. Other examples of categories are Clpital budgeting, allocation of resources, distribution. For each category of decision, an easy-to-apply prescribed model and solution approach have been developed, generally as quantitative formulas.

This approach is called managemellt science. Therefore, it is possible to use a scientifIC approach to automating portions of managerial decision making. The MS process adds a new step 2 to the process described in Section 1. Defme the problem i.

Construct a model that describes the real-world problem. Identify possible solutions to the modeled problem and evaluate the solutions. Compare, choose, and reconmlend a potential solution to the problem. MS is based on mathematical modeling i.

Modeling involves transforming a real-world problem into an appropriate pro- totype strucrure model. Computerized methodologies can fmd solutions to the standard Cltegory models quickly and efficiently see Chapter 4. Some of these, such as linear progranuning, are deployed directly over the Web. ADS , sometinles also known as decisioll User name: Application Case 1. The company had a year-old pricing and promotion system that was very labor intensive and that could no longer keep up with the pricing decisions required in the fast- paced grocery market.

The system also limited the company's ability to e xecute more sophisticated pricing strategies. Giant was interested in executing its pricing strategy more consistently based cu a defmitive set of pricing rules pricing rules in remiI might include rela- tionships between national brands and private-label brands, relationships between sizes, ending digits such as '"9," etc.

In the past, many of the rules were kepi: Giant Foods worked with DemandTec to deploy a system for its pricing decisions. It can handle large numbers of price changes, and it can do so without increasing staff. The system allows Giant Foods to codify pricing rules with "narural language" sentences rather than having to go through a techni- cian.

The system also has forecasting capabilities. These capabilities allow Giant Foods to predicr the impact of pricing changes and new promotions before they hit the shelves. Giant Foods decided to implement the system for the entire store chain.

The system has allowed Giant Foods to become more agile in its pricing. It is now able to react to competitive pricing changes or vendor cost changes on a weekly basis rather than when resources become available. Giant's productivity has doubled because it no longer has to increase staff for pricing changes.

Giant now focuses on '"maintaining profitability while satisfying its customer and maintaining its price image. ADS initially appeared in the airline industry, where they were calJed revellue I".. Today, many service industries use similar pricing models. In contrast with management science approaches, which provide a model -based solution to generic strucrured problems e.

However, such solutions may benefit from data and information generated from cor- porate or external data sources see Part III and Chapter Intuition and judgment may playa large role in these types of decisi ons. Computer Support for Semistructured Problems Solving semistructured problems may involve a combination of standard solution proce- dures and human judgment, MS can provide n"KXIels for the portion of a decision-making iJiOblem i.

It is a computer-based support system for management decision makers who deal with semistructured problems. Note that the teml decisioll support system, like mallagement information system MIS and other terms in the field of IT, is a content-free expression i. Therefore, there is no universally accepted definition of oss. We present additional definitions in Chapter 3. Actually, DSS can be viewed as a conceptual methodology-that is, a broad, umbrella tenn.

DSS as an Umbrella Term The tenn DSS can be used as an umbrella term to describe any computerized system that supports decision making in an organiwtion. An organization may have a knowledge management system to guide all its personnel in their problem solving. Another organiza- tion may have separate support systems for marketing, fmance, and accounting; a supply- chain management SCM system for production; and several expert systems for proouct repair diagnostics and help desks.

DSS encompasses them all. The problem to be solved was unstructured, but the initial analysis was based on the decision maker's strucrured defmition of the situation, using an MS approach.

The DSS was built using data. The development plat- fonn was a spreadsheet. The DSS provided a quick what-if analysis see Chapter 4. FurthemlOre, the DSS was flexible and responsive enough to allow managerial inruition and judgment to be incorporated into the analysis. The conlpany sells products in hundreds of proouC! In this highly competitive retail market, it is important to have enough product quantity on hand to provide a high service level to customers, but excess inventory costs money, so developing an optimal inventory policy is essential in achieving a decent profit.

GSK User name: GSK collects all of its sales and demand infor- mation through the supply chain planning system. From this system, it extracted the historical forecast and demand, month.

GSK developed a model that takes these inputs and estimates the safety stock measured in weeks forward carryover [WFC. The model can determine how changes in the safety stock affect the customer level. The entire model was built using a spread- sheet tool Microsoft Excel. The Excel-based DSS enables the company to evaluate many situ- ations. Because of the stochastic nature of demand for many products, the model includes a simulation feature, which all ows the company to analyze the impact of uncertainty in demand on the optimal safety stock level.

Managers have found the DSS to be very helpful in making inventory decisions. Dedskm suppan Systems. How can a thorough risk analysis, like the one in Application Case 1. How can the judgment factors be elicited, quantified, and worked into a model? How can the results be presented meaningfully and convincingly to the execu- tive?
