web| Process | design | Problems creating a good web site can be challenging, from design to database integration, so many different parts leave a lot of room for mistakes. To reduce the risk of Web project failure, we need to have a process model to guide the development process. Unfortunately, many web designers have adopted a development approach that might be called N I K e-they just do it, and they rarely think about prospects and plans.
