Design
• Think “blueprint”
• Systems are broken down into successively
smaller levels until discrete working entities are
denoted
• Describe each of those entities and how they
interface with their partner components to make
the whole

Operations and Support
•
•
•
•
Think “system go-live”
Manage minor changes & updates
Support of users & system components
New versions not part of O&S. New versions
mean a new project.
