Conquering the MonsterConquering 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.

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???

Inspirational question:

How to convert coffee beans to grounds?

How to refine / decompose a context diagram in PRD to high level Data Flow Diagram in PSD?

How to expand PSD from PRD?

Why SPMP is with PSD, and what is the key for SPMP?
