L1-S13Introduction 2003 SJSU – CmpE---- M.E. Fayad 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. Debate: –Understanding the problem is more important than coming up with solutions for it. –There is always a fuzzy line between the problem space and the solution space. Essay Topic 1: Name and describe a method that allows for analysis / design / implementation in the same time? Essay Topic 2: What is the “what” in the problem space? 13 Discussion Questions

L1-S14Introduction 2003 SJSU – CmpE---- M.E. Fayad 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? 14 Questions for the Next Lecture
