Variability Features: Extending Sustainability Decision Maps via an Industrial Case Study

“…By defining the researcher as the DM specialist and modeling entity, and the industry partner as the knowledge specialist and validation entity, we observed a considerable increase in time efficiency. While previous work spent several days teaching the methodology for DMs and the SAF toolkit itself [8], our working session took only about three hours to produce the initial DM. In addition, new perspectives on Zahori and its overall sustainability goal emerged from the inquiries of the researchers.…”

“…In contrast to previous work [8], where the knowledge on DMs was first taught to industrial participants, who could then independently apply it, the methodology used in this study allowed to efficiently construct a DM, while ensuring both the completeness of the information modeled, and the syntactic/semantic correctness of the DM. The output of this phase was a DM of Zahori, capturing its main features, sustainability concerns, and related dependencies (see Section III-A for the concrete DM and its documentation).…”

Expressing the Adaptation Intent as a Sustainability Goal

“…The novel idea we put forward in this paper is to express the adaptation intent of a software-system as a sustainability goal it needs to satisfy, i.e., the network of quality concerns balanced over time [15]. So far, sustainability goals have been used in software projects to describe qualities that need to be minimized, maximized, or kept balanced to make a project sustainable or ensure that a project contributes to sustainability.…”

Software Sustainability in the Age of Everything as a Service

“…Architecting sustainable systems in general is acknowledged to be one of the grand challenges in modern software engineering, as discussed by Venters et al [30]. The need for a more comprehensive view which (i) integrates the various dimensions while taking into consideration their relations and potential tradeoffs, and (ii) enables further investigation into the relations of other software qualities and metrics, is also discussed by Condori-Fernandez et al [4] and Lago et al [24]. Beyond these general issues with sustainability in software architecture, however, there are additional concerns that rise due to infrastructure, platforms, and software being offered and used as a service, both on and off premises.…”
