abstract = {Context: Engineering Ambient Assisted Living applications for the elderly is challenging due
to the diversity and rapid changes of both end users’ needs and technological environment
equipment.
Objective: Assistive applications can be provided as combinations of functionalities provided by
IoT devices. With the pervasive availability of functionally equivalent IoT devices, they should
be selected according to the specific deployment context in terms of user needs and conditions,
device availability, and regulations when the operative context dynamic conditions can be set.
Such selection is the objective of this work.
Methods: We rely on a conceptual framework for self-adaptation as the enabler for a run-
time decision-making process. It allows for representing relations among IoT devices, the
functionalities they deliver, and the different modalities these functionalities are provided with
in terms of goals, devices, and norms. The framework is based on three fundamental principles:
(1) high-level abstractions separating the expected functionality, how it can be delivered, and
who is responsible for its delivery; (2) AAL applications as the run-time composition of atomic
functionalities; (3) centrality of the user in the system.
Result: The Device-Goal-Norm framework is proposed to specify diagrams for different AAL
applications, together with the semantics to transform these diagrams into run-time models. We
also provide a running implementation of a run-time model based on the belief–desire–intention
paradigm.},

Goal-oriented approaches in requirements engineering provide concepts and techniques to support this analysis. A variety of goal-oriented modelling methods are available, together with guidelines for their application, as well as real case studies success stories. Our long term research objective is to derive useful suggestions for practitioners about which information sources are more promising for performing effective goal-oriented analysis and requirements elicitation of a complex domain, as well as about possible limits and pitfalls. As a first step towards this objective we perform a retrospective case study analysis of a project in the domain of ambient assisted-living residences for people affected by Alzheimer's.

Understanding complex organisations in terms of their stakeholders' goals, intentions and resources, is a necessary condition for the design of present day socio-technical systems. Goal-oriented approaches in requirements engineering provide concepts and techniques to support this analysis. A variety of goal-oriented modelling methods are available, together with guidelines for their application, as well as real case studies success stories. Our long term research objective is to derive useful suggestions for practitioners about which information sources are more promising for performing effective goal-oriented analysis and requirements elicitation of a complex domain, as well as about possible limits and pitfalls. As a first step towards this objective we perform a retrospective case study analysis of a project in the domain of ambient assisted-living residences for people affected by Alzheimer's. In this paper we describe the design of this study, present an analysis of the collected data, and discuss them against the proposed research questions, towards investigating the effectiveness of information sources for goal modelling and requirements elicitation in complex domains

The centrality of users in the design and development of complex systems, such as service-based applications, calls for new methodologies and techniques to extract and represent user needs and to translate them into real processes. In this short paper, we describe the integration of concepts and analysis techniques of different approaches, namely Goal-Oriented Requirements Engineering, User-Centred Design and Process-Oriented Modeling, that are being developed in the context of two projects related to Ambient Assisted Living and Internet of Services.
