A Database Architect makes data work for machines.An Information Architect makes information work for people.

- Jesse James Garrett

As an Information Architect I help my company by making it easy for our customers to find our products in our website (or complete their tasks on our products). I organize huge amounts of information on websites and intranets so people can find what they are looking for.

Why IA?

1. Cost of Finding Information

2. Cost of not finding information

3. Cost of construction

4. Cost of training

5. Brand Value

Example of Poor IA

A good Information Architecture …

1. Tells you, where you are.

2. Helps you to move to closely related topics/content

3. Helps you browse topics

4. Allows you to manipulate content for better browsing

5. Directs you to basic services (contact, login/logout)

6. Makes it easy to complete your primary goal/task
