This document summarizes the topics covered in Workshop IV of the course BIS 220: Introduction to Computer Systems and Applications. The topics discussed include reasons for systems implementation failures, systems failures at different stages, types of failures, systems planning and selection, systems development methodologies and options, and IT funding and costs. It also provides an overview of the basic systems development life cycle, tools used at different stages, and project management elements. The document concludes with next steps which are to prepare assignments, read recommended materials, and prepare for the final exam in weeks 4-5.
Computer Applications and Systems - Workshop IV
- 1. BIS 220, INTRODUCTION TO COMPUTER SYSTEMS AND APPLICATIONS WORKSHOP IV Raji Gogulapati July 2014
- 2. TOPICS
- 3. Why do Systems Implementations Fail Often? What can be done? Systems Failures Question and Understand
- 5. Types of Failure Types of failure Disaster or Horror Big or Small Forthcoming
- 7. What did we learn so far? Why many new system implementations fail ? What can be done ?
- 8. IS/ IT • Planning • Justification IS/ IT system development methodologies and options • Team effort • Several approaches • Start with investigation and analysis, design, maintenance and review Emphasis • How to deliver • Right information to the right person at the right time!
- 9. Workshop III Review Why Most New Information Systems Fail? Nature of Software Development IS/ IT Planning & Justification IS/ IT System Development Methodologies IS/ IT Funding & Costs Summary Your activities for coming week
- 10. Basic system development framework IS development – intangible, eventually visible Process of design to delivery is repeatable Software engineering – shifts from waterfall paradigm Analogies – limited and not complete Iterative, agile development

- 17. Stages of SDLC Systems investig ation Systems analysis Systems design Program ming and testing Implemen tation Operatio ns and mainten ance
- 18. SupportingTools of SDLC during various stages Prototyping Joint Application Design Upper case tools Lower case tools Examples?
- 19. What are the benefits of planning for Information Systems? What obstacles teams might have to overcome to have their plans heard in an organization? Discuss
- 20. Problem Recognition and Definition User mentions a problem Is it a problem or symptom Establish the need Define the problem
- 21. Technical feasibility (Proof of concept) Economic feasibility (costs vs Benefits) Legal Feasibility (laws and regulations) Operational feasibility (historical acceptance of IT systems, Personnel re-training) Schedule feasibility (balancing time and resource) Feasibility Study
- 23. Goals of systems analysis stage Understand As-Is Determine To-Be Understand current processes Determine requirements for the system being built
- 24. System DevelopmentTools Iterative Development –Theme Design Develop Test Joint Application Development User review Requirements
- 25. System DevelopmentTools Compress cycles, iterative Development –Theme Rapid Application Development Compress SDLC stage time
- 26. Project management terminology Team work Project plan Elements of project management
- 27. Identifying requirements Organizational integration Team management Risk and opportunity management Project control Visibility, status, corrective action, leadership Elements of Project management
- 28. What • IS/ IT planning • justification of investments Did we learn • System development methodologies • Options So far? • How to deliver the right information to the right person at the right time?
- 29. Whatisnext? Who funds IT investments What are the costs involved? Whatisnext? Managing IT Portfolios Evaluation Whatisnext? Monitor, communicate reduce risks
- 30. Workshop III Review Why Most New Information Systems Fail? Nature of Software Development IS/ IT Planning & Justification IS/ IT System Development Methodologies IS/ IT Funding & Costs Summary Your activities for coming week Topics

- 34. Your activities for coming week Prepare and submit assignments as per syllabus. Remember to include all references and use proper citations.The final exam is during week four – week five. Follow Materials Link. Read: Selected Readings specified in Materials tab Refer to your syllabus for details on activities during the workshop
- 35. The chapters recommended from the electronic texts in Materials were used. Some of the figures used in the slides were taken from the chapters in texts. Source for slides on Information Architecture and Information Management are from Principles of Information Systems Management by John Ward Source of slides on Information Systems failures is from Phil Simon’s Why New Systems Fail theory and practice collide.
