3. Systems Analysis and Design is the process people use to create (automated) information systems Systems Analysis & Design Information System 3

4. Information Systems Engineering!Software Engineering! Information Systems Development!Systems Engineering! Systems Analysis and Design! Other names...! Which one? Is there an “official” name? 4

5. A title given to a person who studies the problems and needs of an organization looking for improvement opportunities. Systems Analyst Other names: Software Engineer Systems Engineer Software Developer Programmer/Analyst Nerd or Hacker! (joking!) 5

6. An idea Analysis Design and Implementation Completed Information System SYSTEMS ANALYSIS AND DESIGN: A Condensed (Informal) Perspective Time 6

7. SYSTEMS ANALYSIS AND DESIGN: A Complete (Formal) Perspective Systems Planning Systems Planning Systems Analysis Systems Analysis Systems Design Systems Design Systems Implementation Systems Implementation Systems Evolution Systems Evolution Planning Evolution Implementation Design Analysis 7

8. Systems Analysis and Design is the process people use to create (automated) information systems people procedures data software hardware SA&D 8

9. Systems Analyst’s interactions with people during Systems Analysis & Design SYSTEMS ANALYST Users* Steering Committee* Vendors Programmers & Tech. Staff Database Administrators Managers* * = Stakeholders Systems Analyst may be acting as a Project Manager for some of these interactions. 9

10. Planning Feasibility Study (optional) Requirements Determination Conceptual Design Physical Design Construction and/or Purchase (prototype) Training Conversion - old to new Implementation Evolution - maintenance & enhancements SYSTEMS DEVELOPMENT LIFE CYCLE (SDLC) Analysis Design and Implementation 10

11. Sequential or Traditional SDLC 1. Planning for an information system 2. Feasibility Study (optional) 3. Requirements Determination (gathering) 4. Conceptual design 5. Physical design and/or purchase and/or prototyping 6. Conversion from current system to new/changed system 7. Training 8. Implementation 9. Evolution for enhancements and maintenance Waterfall or Staircase SDLC Planning Feasibility Study Requirements Determination Conceptual Design Physical Design Conversion Training Implementation Evolution “Begin” “End” “Begin” “End” 11

12. Planning Feasibility Study Requirements Determination Conceptual Design Physical Design Conversion Training Implementation Evolution Iterative SDLC Risk Analysis Spiral SDLC SDLC Activities Verification/Test 12

13. The system is for the user A Work Breakdown Structure should be used (ie., SDLC) Systems analysis and design is iterative and overlapping Information systems are capital investments for the business Project manager may have the authority to cancel a project Project documentation is important all along the way Senior management approval/support is very important Principles to Guide Systems Analysis & Design 13
