Hogg explains he doesn't have a technology background. Without that expertise it can be difficult to understand a lengthy, complicated document like a Web site design contract. As it turns out, the blueprint generally takes precedence over the contract. If you okay the blueprint without realizing how it might differ from the contract, you could be out of luck as far as changing essential design elements is concerned. Be sure you know the credentials of the people making changes, Hogg notes.
Time is another important, but touchy, factor.
Web site design is not an exact science. Consequently, the project ran at least five months longer than predicted. There are other issues to be aware of as well. For example, says Hogg, be prepared for the possibility of changes in hosting services. A company might decide to move your server to another location and, consequently charge you more.
