Agent-oriented models are frequently used in disciplines such as requirements engineering and organizational process modelling. i* is currently one of the most widespread notations used for this purpose. Due to its strategic nature, instead of a single definition, there exist several versions and variants, often not totally defined and even contradictory.(More)
Selection of commercial-off-the-shelf software components (COTS components) has a growing importance in software engineering. Unfortunately, selection projects have a high risk of ending up into abandonment or yielding an incorrect selection. The use of some software engineering practices such as the definition of quality models can reduce this risk. We(More)
Selection of software packages from user requirements is currently a central task in software engineering. Selection of inappropriate packages may compromise some business processes and may interfere negatively in the functioning of the involved organization. Success of package selection is currently endangered because of many factors, being one of the most(More)
The selection process is a crucial activity of the development of COTS-based systems. A key step of the evaluation of COTS components carried out during selection is the matching between user requirements and COTS features. We propose a goal-based approach to guide the matching process, using quality models for leveraging goals and COTS features. The(More)
The architectural definition of hybrid software systems is a challenging problem that demands to reconcile stakeholders' strategic needs and components marketplace, whilst defining an appropriate set of services. We have defined a method called DHARMA based on the i* framework. The goal of this paper is to present an experience report about the use of i* in(More)
The selection of Commercial Off-The-Shelf (COTS) components is currently a central activity in the development of information systems. Criteria for selecting COTS components include both technical and non-technical issues. Whilst many catalogues of technical quality factors exist, it is not the case for non-technical ones. In this paper, we propose an(More)
