Information architecture is the science of identifying what you want your web site to do and then creating a blueprint before you start putting the site together. The good blueprint leads to a well designed web site which will provide an excellent customer experience. Brief overview of steps:

• Planning: define site goals, audience, services, and purpose.
• Define the content to meet the stated goals.
• Define the site logical hierarchy which follows industry vocabulary and standards.
• Work with user groups to continue refining the blueprint until it achieves the goals.
