One building, many questions
The college is planning new IT for its buildings. The head asks: "Will it be safe?" The finance manager asks: "What will it cost?" A teacher asks: "Will it work in my room?"
One diagram cannot answer all three. So architects draw different pictures for different people, using five key terms.
Key words
| Word | What it means |
|---|---|
| System | the thing being described, such as the college network |
| Stakeholder | a person or group with an interest in the system |
| Concern | something a stakeholder cares about, such as cost, safety or speed |
| Viewpoint | a way of looking at the system, set up to answer certain concerns |
| View | the actual picture or document made by using a viewpoint |
| Architecture description | the set of views and notes that describes the architecture |
| Network | computers and devices joined so they can share data |
| Firewall | a device or program that allows or blocks traffic by rules |
The cells students fill in are left blank in this preview.

Note
I can explain system, stakeholder, concern, viewpoint and view, and show how they link in an architecture description.

The five terms
The system is the thing described. The stakeholders are the people with an interest in it. Each stakeholder has concerns.
A viewpoint is a way of looking that answers certain concerns. A view is the picture or document that you make with that viewpoint.
