9. What are the differences between requirement analysis and software design? What are the requirement analysis and software design? Analysis & Design 9 ISISTAN Research Institute – Tandil, Argentina -- M.E. Fayad

10. Analysis & Design • Problem space • Analysis • One problem • The “What” Fuzzy line • Solution space • Design • Many solutions • The “How” 10 ISISTAN Research Institute – Tandil, Argentina -- M.E. Fayad

11. What are the differences between analysis & design? T/F Software design is part of the software life cycle. Software design is part of the software maintenance cycle. Define: Domain-specific software engineering Discussion Questions 11 ISISTAN Research Institute – Tandil, Argentina -- M.E. Fayad

12. Define the following terms Methodologies and Paradigm. Method and Process Model and View Technique and Tool Environment Heuristics What are the differences between a method and a process? What are the differences between a model and a view? Questions for the Next Lecture 12 ISISTAN Research Institute – Tandil, Argentina -- M.E. Fayad

13. Task 1: Think About a problem statement for your team Project (see sample problems on the course web site). This is due immediately. Task 2: Identify the team members of your team. E – Mail me their names, e-mails, phone numbers. Please note that problem statements must be submitted electronically as MS Word format to adiaz@exa.unicen.edu.ar Tasks for Next Lecture 13 ISISTAN Research Institute – Tandil, Argentina -- M.E. Fayad
