Goal-Oriented approaches such as KAOS rely on goals to direct their process of eliciting requirements: a goal is an objective the system under consideration should achieve and represents a system property that may reflect either a functional (e.g. a service provided by the system) or a non-functional (e.g. security, performance) requirement; its satisfaction may imply the participation of several agents and the resolution of possible obstacles that may arise. The KAOS approach offers an unambiguous method for requirement decomposition and may provide a set of heuristics to approaches where one does not exist. Viewpoint-Oriented approaches such as PREview focus on gathering information pertaining to the problem from several agents that may have different, often equally valid, and incomplete perspectives on the problem. These partial intakes reflect their different responsibilities, roles, goals, or interpretations of the information sources; hence the combination of the agent and its input on the system is called a viewpoint. PREview benefits from a particularly lightweight approach to requirements encapsulation, but fails to provide a set of heuristics for the process of identifying the system's requirements. Considering the issues identified in each approach, it is verifiable that both approaches are complementary: on the one hand, KAOS offers a set of requirements elicitation heuristics through goal decomposition; on the other hand, PREview is a lightweight approach to viewpoint oriented requirements engineering, tailored especially for integration, however lacks a more systematic mechanism to guide the requirements elicitation process. The objective of this dissertation is therefore to propose a hybrid approach that builds on the PREview approach and brings together the benefits of the KAOS approach. The result is synergetic where, for example, completion is better addressed by providing a set of heuristics for requirement elicitation.FCT - UNLAraújo, JoãoRUNPimenta, Manuel Filipe2009-07-30T12:57:06Z20092009-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/2024enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-05-22T17:06:39Zoai:run.unl.pt:10362/2024Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-22T17:06:39Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
