'Garbage in Garbage out!' This is very true when user requirements are not addressed accurately in Web (or any) Application development. Adding fuel to this fire is the ever-changing business requirements that force these web (or any) applications to change and evolve. In order to deliver web applications that meet user requirements, within budget and time constraints, it is important to use appropriate methodologies, tools and techniques suitable for a dynamic environment. Experts in Software Development have been researching and practicing many approaches to over come these issues. However, after a decade into Web application development, only a few of these approaches are effectively used in this domain. This paper discusses use of two such approaches: (a) use of Components and (b) End User development that can be effectively used in combination for Web Application development. In our work in the Small to Medium Enterprise (SME) sector we have developed a set of Components that allow End Users to assemble, deploy and run Web Applications. We have incorporated these Components into a framework that facilitates the deployment of these Components developed by developers.

End-user development is proposed as a solution to the issues business people have when getting web applications developed. In this paper, we have presented a meta-model for web based information systems to support End-user Development. End-users can actively participate in web application development using tools to populate and instantiate the meta-model. The meta-model we created is based on three abstraction levels: Shell, Application, and Function. At Shell Level, we model aspects common to all business web applications such as navigation and access control. At Application Level, we model aspects common to specific web applications such as workflows. At Function Level, we model requirements specific to the identified use cases. Inheritance and Overriding properties of the meta-model provide a balance between ease and flexibility when developing business information systems. The key aspect that underpinned this research work is the view-"software is a medium to capture knowledge rather than a product". Meta-model will help end-users to participate in web application development activities.
