“…First, we believe that our strategy is transferable to real world situations, but this would require more effort towards tool and method development. Second, we would like to investigate how previous work on viewpoints [25] could be used in conflict analysis.…”

The development of complex information systems calls for conceptual models that describe aspects beyond entities and activities. In particular, recent research has pointed out that conceptual models need to model goals, in order to capture the intentions which underlie complex situations within an organisational context. This paper focuses on one class of goals, namely nonfunctional requirements (NFR), which need to be captured and analysed from the very early phases of the software development process. The paper presents a framework for integrating NFRs into the ER and OO models. This framework has been validated by two case studies, one of which is very large. The results of the case studies suggest that goal modelling during early phases can lead to a more productive and complete modelling activity.

“…Fagan 1976, presented the concept of inspections, and they have been using it as a dominant technique for detecting errors [10]. Literature shows that inspections can identify 50-90 % of defects [9].…”

“…This aids in ensuring the completeness and correctness issues in the requirements. In order to get benefit from this principle, different views must be compared and then analyzed in a systematic fashion (Freeman & Leite, 1991). The main goal of this process is to facilitate elicitation process.…”

Requirements validation makes sure that the requirements written in software requirements specification (SRS) must be complete and consistent and are according to the customer's needs. It ensures the validity of user requirements by eliminating ambiguities and inconsistencies from SRS. Several techniques for requirements validation have been discussed in the literature. This paper gives an overview of requirements validation techniques which have been practicing in industry, which includes requirements inspections, requirements prototyping, requirements testing and viewpoint-oriented requirements validation. This paper also highlights pros and cons of these techniques. In requirements testing, special attention is given to TCD inspections.

“…1 Carroll [5], taking into account usage aspects, believes that scenarios allow us to know the problem, to unify criteria, to gain clients/users compromise, to organise the involved details and to train new participants. The use of scenarios, as a way of understanding the domain in which the software will perform, has been recommended by several authors [6][7][8][9] and those proposals became very important for extending the use of scenarios in real practice.…”
