Comparing GORE Frameworks: i-star and KAOS
نویسندگان
چکیده
Goal-Oriented Requirements Engineering (GORE) is an approach to requirements engineering dealing with intentionality in accordance with the relations among different actors. KAOS and i* (i-star) frameworks have been receiving many references as being important GORE proposals. This paper presents an conceptual analysis comparing characteristics of those methods giving examples related to actors’ relations definition, goal organizational model, tasks representation, risk analysis, and non-functional requirements. The aim of this work is to show both frameworks benefits and drawbacks. We believe that this analysis helps the understanding of the core concepts of GORE as well as it draws attention to key representation issues for both KAOS and i*.

Model-Driven Development for Goal-Oriented Requirements Engineering: The Case of i* and KAOS Approaches
Goal-Oriented Requirements Engineering (GORE) has received increasing attention over the past few years. There are several goal-oriented approaches, each one using different kinds of models. We argue that it would be useful to relate them or even perform transformations among them automatically, in order to understand their similarities and differences, their advantages and disadvantages, allow...
متن کاملA Framework to Evaluate Complexity and Completeness of KAOS Goal Models
Goal-Oriented Requirements Engineering (GORE) approaches have been developed to facilitate the requirements engineers work by, for example, providing abstraction mechanisms to help eliciting and modeling requirements. One of the well-established GORE approaches is KAOS. Nevertheless, in largescale systems building KAOS models may result in incomplete and/or complex goal models, which are diffic...
متن کاملGoal-Oriented Requirements Engineering and Enterprise Architecture: Two Case Studies and Some Lessons Learned
An enterprise-architecture (EA) is a high-level representation of the enterprise, used for managing the relation between business and IT. [Problem] Ideally, all elements of an enterprise architecture can be traced to business goals ad vice versa, but in practice, this is not the case. In this experience paper we explore the use of goal-oriented requirements engineering (GORE) techniques to impr...
متن کاملEvaluating the Effectiveness of a Goal-Oriented Requirements Engineering Method
As an attempt to answer the need for methods and tools in requirements engineering (RE) which are domain specific and can address the main RE objectives (REOs), and the growing interest in the goal oriented requirements engineering (GORE) approach that overcomes the inadequacy of the traditional systems analysis approaches, we systematically evaluate the KAOS method, and the Objectiver tool, us...
متن کاملAutomated Completeness Check in KAOS
KAOS is a popular and useful goal oriented requirements engineering (GORE) language, which can be used in business requirements modelling, specification, and analysis. Currently, KAOS is being used in areas such as business process modelling, and enterprise architecture (EA). But, an incomplete or malformed KAOS model can result to incomplete and erroneous requirements analysis, which in turn c...
