Intro

Lets introduce Two types of Design methodology.

White box design

What we follow now in most cases:

• Requirements doc completed
• Sys analyst creates and documents Design based on Requirements doc
• Design goes through review process
• developer codes based on Design doc
• QA tests based on Design doc

Black box design

Alternative approach:

• Requirements doc completed
• Developer codes based on Requirements doc (creating functional Prototype)
• Sys analyst creates and documents Design based on Prototype
• Design and Prototype go through review process
• QA tests based on Design doc
