1、SADM 5/ed CASE STUDY 4 Milestone 2: Problem AnalysisPage: 2-1 MILESTONE 2 PROBLEM ANALYSIS: SynopsisTheres an old saying that suggests, “Dont try to fix it unless you understand it.” With those words of wisdom, the next milestone of our project is to study and analyze the existing system. There is a
2、lways an existing system, whether computerized or manual or some of both. The problem analysis phase provides the project team with a more thorough understanding of the problems, opportunities, and/or directives that triggered the project. Indeed, the analyst frequently uncovers new problems and opp
3、ortunities. The problem analysis phase may answer the questions, “Are the problems worth solving?” and “Is a new system worth building?”The purpose of the problem analysis phase is threefold. First and foremost, the project team must gain an appropriate understanding of the business problem domain.
4、Second, you need to answer the question, “Are these problems (opportunities, and directives) worth solving?” Finally, you need to determine if the system is worth developing. The problem analysis phase provides the systems analyst and project team with a more thorough understanding of the problems,
5、opportunities, and/or directives that triggered the project. In the process, they frequently uncover new problems and opportunities.In this milestone you will perform Cause-Effect Analysis and document your findings using the Problems, Opportunities, Objectives, and Constraints Matrix. The PIECES fr
6、amework, originally developed by James Wetherbe, and then adapted by the authors, can serve as a useful tool to classify the various problems, opportunities, and directives identified in Milestone 1.: ObjectivesAfter completing this milestone, you should be able to: Perform Cause-Effect Analysis to
7、be able to thoroughly understand a systems problems, opportunities, and/or directives that triggered the project. Use and understand the PIECES framework for classifying problems, opportunities, and directives. Complete the Problems, Opportunities, Objectives, and Constraints Matrix.: PrerequisitesB
8、efore starting this milestone the following topics should be covered:1. The problem analysis phase Chapters 3 and 52. Problem analysis techniques Chapter 63. PIECES Framework Chapters 3 and 54. Milestone 1 Solution: AssignmentNow that you have completed the survey of the system, and gained approval
9、to proceed, you can now attempt to gain a better understanding of the current system. In this assignment you will use your results of Milestone 1, plus the case background information and the user interview, to perform cause-effect analysis. The results of this activity will provide you a better und
10、erstanding of the problems, opportunities, and constraints of the current system.: Activities1. To complete the Problems, Opportunities, Objectives, and Constraints Matrix, use the interview presented in this milestone. Use the PIECES framework as a model to classify the problems, opportunities, and
11、 directives. Deliverable format and software to be used are according to your instructors specifications. Deliverables should be neatly packaged in a binder, separated with a tab divider labeled “Milestone 2,” and optionally accompanied with a Milestone Evaluation Sheet.References:Case BackgroundCas

13、 report for the phase. This deliverable was not discussed in the narrative because students need to be exposed to modeling (data, process, & interface) before this report can be completed. For those ambitious individuals who are familiar with those skills and wish to be challenged, use the detailed
14、study report outline found in Chapter 5 of the textbook, as a guideline. Another advanced option is to develop one or more fishbone diagrams for problems outlined in the case. To complete this advanced option, you may need to make some assumptions about causes and effects.Study Report:Due: _/_/_Time
