The Web has very rapidly become central to many applications in diverse areas. As our reliance on Web-based applications continues to increase and the Web systems supporting these applications become more complex, there is growing concern about the manner in which the Web-based systems/applications are created and their quality, integrity and maintainability. The development of Web-based systems has generally been ad hoc, resulting in poor quality and maintainability. In the recent times, there have been many failures of Web applications due to a variety of problems and causes. The way the developers address these problems is critical to deploying successful large-scale Web applications.This tutorial addresses these issues and offers a holistic approach to managing the complexity of development of Web-based systems and Web applications. It highlights the various real-world issues, challenges and considerations in development of large Web applications, compared to traditional software development, and recommends the Web engineering approach that Web/software developers could follow.Web engineering deals with systematic, disciplined and quantifiable approaches to development, operation, and maintenance of Web-based systems and applications [1-9]. It embodies engineering principles and practices to Web application and Web site development and draws on software engineering and a number of contributing disciplines.Specifically, the tutorial aims to:• Highlight the problems, complexity and challenges of Web application development relative to software development• Offer a holistic approach to development of Web applications• Present Web development methodologies and processes• Address the issues of scalability, maintainability, usability, configuration management and other non-technical aspects• Recommend suitable Web testing and quality assurance approaches• Discuss project management issues specific to Web developmentThis tutorial is specifically targeted to address the needs of a growing community of software practitioners, Web application developers, project managers IT and business professionals, ecommerce system implementers, academics, researchers and students.

There is a growing demand for redesigning the existing Web sites. Many organisations want their sites evaluated, or audited, with recommendations to improve them. Historically, auditing has related to financial matters. It is now applied to other disciplines such as quality, environment, safety, information systems and security. Correspondingly, there are many national and international standards for such audits. Operationally, a financial audit is an independent and expert opinion on how an organisation handles its resources and may recommend, if necessary, changes in the organisational practices to meet the established standards and obligations. In contrast, a Quality audit is meant to aid continuous improvement strategies. The definition and role of a Web site audit are not so clear. This paper addresses these two problems. First, it establishes a general context for Web site auditing in terms of the types of Web-based systems, the stages of Web development and the need for frequent re-engineering of the existing sites. The paper then argues that Web site auditing, as currently understood, is qualitatively different from normal auditing and recommends that it be an integral part of the re-engineering strategy and not be seen as mainly a reassurance exercise.

WEB ENGINEERING is a rapidly emerging new discipline focusing on various aspects of successful development and deployment of large, complex Web sites and Web-based systems. Since 1997, interest in Web Engineering has been growing [1-9] and will continue to grow as Web-based systems become critical elements in a large number of applications.
