Major arguments for web engineering as a new discipline are:
* WIS (Web Information System) and WIS development process are different and unique.
* Web engineering is multi-disciplinary; no single discipline (such as software engineering) can provide complete theory basis, body of knowledge and practices to guide WIS development.
* Issues of evolution and lifecycle management when compared to more 'traditional' applications.
* Web based information systems and applications are pervasive and non-trivial. The prospect of web as a platform will continue to grow and it is worth being treated specifically.
