In this chapter you will learn: How do you create the software tools needed for your organization? What main options exist for building information systems? How do you control a major development project? Why is control so important? Is SDLC always the best approach? What other methodologies could be used?,. | Introduction to MIS Chapter 12 Systems Development Jerry Post Technology Toolbox InfoPath Technology Toolbox: Programming in Excel Cases: Government Agencies 1 Outline How do you create the software tools needed for your organization? What main options exist for building information systems? How do you control a major development project? Why is control so important? Is SDLC always the best approach? What other methodologies could be used? How do you analyze and annotate a process-based system? How is object-oriented design different from process design? Can software be located in different places? 2 Systems Development 3 $ 2012 2013 Runaway Projects Technical measures 2 - 5 times over budget 2 - 5 times behind schedule Missing technical objectives Design problems Duplication of efforts Incompatibilities User/designer conflicts 2011 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 2014 4 Common Problems Confusion over who is working on each part. Program portions do not work together. Users have minimal and conflicting input. Programmers and developers leave. Work is duplicated or discarded. Goals are uncertain or changing. Cafasso 1994 Success & Failure Reasons for Success User Involvement Executive management support Clear requirements Proper planning Realistic expectations Reasons for Failure Lack of user input Incomplete requirements Changing requirements and specifications Lack of executive support Lack of technical skills 6 Build or Buy Options Purchase complete solution Assemble from components Outsource or contract programmers Custom programming Development time Longer development time means more risk, possibly higher costs. But it also enables you to create a more customized solution. Primary Methodology Choices Prototyping End user development Systems development life cycle Large projects, formal control Single user, reports and one-time computations Decision support, analyses, and reports Custom Code Get custom/unique . | Introduction to MIS Chapter 12 Systems Development Jerry Post Technology Toolbox InfoPath Technology Toolbox: Programming in Excel Cases: Government Agencies 1 Outline How do you create the software tools needed for your organization?
