86   Part I  •  Decision Making and Analytics: An Overview

                                    information system supported decision making. Indeed, many previous technology-
                                    related waves (e.g., business process reengineering (BPR), knowledge management,
                                    etc.) have faced mixed results mainly because of change management challenges and
                                    issues. Management of change is almost an entire discipline in itself, so we recognize its
                                    importance and encourage the readers to focus on it independently. Implementation also
                                    includes a thorough understanding of project management. Importance of project man-
                                    agement goes far beyond analytics, so the last few years have witnessed a major growth
                                    in certification programs for project managers. A very popular certification now is Project
                                    Management Professional (PMP). See pmi.org for more details.
                                         Implementation must also involve collecting and analyzing data to learn from the
                                    previous decisions and improve the next decision. Although analysis of data is usually
                                    conducted to identify the problem and/or the solution, analytics should also be employed
                                    in the feedback process. This is especially true for any public policy decisions. We need
                                    to be sure that the data being used for problem identification is valid. Sometimes people
                                    find this out only after the implementation phase.
                                         The decision-making process, though conducted by people, can be improved with
                                    computer support, which is the subject of the next section.

                                    In Chapter 1, we discussed the need for computerized decision support and briefly
                                    described some decision aids. Here  we relate specific technologies to the decision-
                                    making process (see Figure 2.2). Databases, data marts, and especially data warehouses
                                    are important technologies in supporting all phases of decision making. They provide
                                    the data that drive decision making.
                                    support for the intelligence Phase

                                    The primary requirement of decision support for the intelligence phase is the ability to scan
                                    external and internal information sources for opportunities and problems and to interpret
                                    what the scanning discovers. Web tools and sources are extremely useful for environmental
