In web system development, the Non-Functional Requirements (NFRs) are typically considered only briefly during the requirements elicitation stage and not rigorously articulated by either web developers or the client. This paper reports on an investigation into this issue involving interviews with web developers who were engaged in commercial web development projects. The results from this qualitative research highlight that web developers commonly do not pay sufficient attention to NFRs. This arises due to uncertainty, lack of time, lack of knowledge in the importance of NFRs and partly because NFRs are not readily available and documented from previous similar projects. Web developers also do not elicit NFR at the same time and at the same level of details as Functional Requirements (FRs). This study highlights that exploring the domain at an early stage of development will help developers to better understand NFR. A lack of rigour in articulating NFRs may significantly impact on the development effectiveness and the quality of the resulting web system. An evaluation of NFRs may also lead to discovering new FRs.

Increasingly, IT systems and Web systems in particular, fall into the class of applications where the scope of the application to be developed cannot be clearly articulated a priori. This is for a range of reasons, but is at least in part due to the complex inter-dependencies which exist between different aspects of the problem domain. While Whereas the core system requirements might be clear, the domain inter-dependencies lead to ancillary requirements which are only identified as the emerging system and its relationship to the domain are understood. A key mechanism in supporting the development of this understanding is the exploration of application pilots or prototypes, and the subsequent identification of solution or problem domain issues. The resolution of these issues will often play a crucial role in supporting the development of domain understanding and hence project scope. In this paper we explore this phenomenon by analysing issue handling across a range of case studies. We describe a model of the issue resolution process and highlight those issues which are most likely to assist in clarification of project scope.
