Software Engineering at Azusa Pacific University Conquering the Monster Capstone Project via Structured System Analysis & Design September 2, Azusa Pacific University, Azusa, CA 91702, Tel: (800) Department of Computer Science,

Software Engineering at Azusa Pacific University September 2, Azusa Pacific University, Azusa, CA 91702, Tel: (800) Department of Computer Science, Conquering the Monster Software Engineering Project is like a monster that overwhelms and frustrates us all the time -- It seems to be a BIG headache to develop a software engineering project:  How to get a project started is really weird You have to start with a big cloud, and what is next step is still up in the air.  How to get the job done is more headachy You start with a cloud, you may have done a big mess – endless work makes you feel hopeless.

Software Engineering at Azusa Pacific University September 2, Azusa Pacific University, Azusa, CA 91702, Tel: (800) Department of Computer Science, Conquering the Monster Conceptual System Operational System SSAD Question ourselves  PR#2-2 Who should design?  PR#2-3 What are design constraints  PR#4-1 / PR#4-2 How to design  PR#3-3 Prepositions of MMM  PR#3-4 MMM after 20 Years What we have learned? How to apply to design?

Software Engineering at Azusa Pacific University September 2, Azusa Pacific University, Azusa, CA 91702, Tel: (800) Department of Computer Science, Conquering the Monster Conceptual System Operational System SSAD There is a gap between conceptual system and operational system Big problem with SSAD How to start with conceptual sys? How to bridge the gap in between?? How to end at operational system???
