“…As diferentes técnicas de pontos de vista especificam quais dados devem ser obtidos das visões, como representá-los e processá-los, variando o grau de formalização e automatização da aplicação da técnica e o custo de sua execução. Por exemplo, a técnica de Leite (1989), direcionada para a validação de requisitos, define uma linguagem baseada em LISt Processing language (LISP) para descrever as visões e permite detectar, automaticamente, conflitos entre elas.…”

Uma longa estrada percorrida. Mérito do autor, mas não só. Agradecimentos devem ser prestados. Omissões não existem, apenas esquecimentos. Dos nomes, não dos fatos. Perdoem esta pessoa cujo dom para guardar nomesé tão falho, mas lembrem-se de que o que importa são as pessoas, não o conjunto restrito e limitado de letras que tentam resumir tanto em tão pouco.À Elisa, pela primeira orientação em trabalho científico. Ao Flávio, vulgo X, pelo apoio, até mesmo quando em tratamento médico, e pelas saudáveis polêmicas. A ambos pelo incentivo a seguir o caminho da pesquisa e pelas recomendações para o Mestrado. Agradecimentos também aos outros professores que apoiaram essa escolha: Dino (Edmundo), Maurício, Morandini (Marcelo).

Viewpoints-based requirements engineering is an active area of research. This paper provides a critical evaluation of a particular technique for the early validation of requirements using viewpoints. The technique is limited to the syntactic analysis of requirements and lacks a conflict resolution strategy. This paper describes an approach to the very early validation of requirements based on learning about the viewpoints and building models of their behaviour. The method is a collection of domain-independent heuristics to build internal models of the viewpoints that record their performance in providing information, assessing information, and resolving conflicts between viewpoints.

“…The term "viewpoint" has been defined and deployed in a variety of settings in software engineering, particularly in the domain of requirements engineering; e.g., [23], [25], [31] and [38]. In our framework, we have attempted to generalise and formalise the definition of a viewpoint to facilitate its manipulation for composite system development.…”

“…In Dardenne et al [7] a goal-directed approach to composite system development is described, while Feather [13] suggests using many, parallel "evolutionary transformations", which may then be merged by replaying them sequentially. Leite [25] demonstrates a viewpoint analysis strategy for early validation of the requirements elicitation process (so-called viewpoint resolution).…”

Composite systems generally comprise heterogeneous components whose specifications are developed by many development participants. The requirements of such systems are invariably elicited from multiple perspectives which will overlap, complement and contradict each other. If these requirements are developed and specified using multiple methods and notations respectively, then it is necessary to express and check the relationships between the resultant specification fragments.In this paper we deploy multiple "ViewPoints" that hold partial requirements specifications, described and developed using different representation schemes and development strategies. We discuss the notion of inter -ViewPoint communication in the context of this ViewPoints framework, and propose a general model for such communication. We elaborate on some of the requirements for expressing and enacting inter-ViewPoint relationships, and use fragments of the requirements specification method CORE to illustrate our model. * Since CORE uses the term "viewpoint" as part of its terminology, we substitute the term "agent" in its place to avoid the clash in nomenclature.
