A key Web designer strategy is to reach consensus, seek to approve incremental development of the project as work proceeds, and move on toward a productive outcome. In Web design, you simply must organize your workflow, from design through production. My experience has shown that graphic design and production alone, consumes the largest block of time. The time you can spend in design before you actually produce the work is time well spent. In fact, I try to anticipate and plan for 75 percent of my time invested in design, and 25 percent of my estimated time in production.
Design time is relatively less costly than production time.
What you want to avoid is having to do things over and over again. Your interface design is crucial because it must work on two levels. You Web design should provide a viewfinder to your information, and it should also have an intuitive design that invites users to stay and retrieve more information. Your interface should automatically teach the visitor how to use the program through intuitive conventions such as rollover buttons, hyperlinked menus, navigation bars, and it all combines to create one complex network of information. This is why an alpha test of your interactive design is important and useful.
