“…The concept of sustainability has emerged as an area of growing interest in the field of software and requirements engineering [10,11,12,13,14,15,16]; which is understood as the 'capacity' of a system 'to endure' [17]. A closely related term, sustainable development, was defined by the Brundtland Commission as 'meeting the needs of the present without compromising the ability of future generations to meet their own needs' [18].…”

Requirements Engineering (RE) plays a critical role in software system development and is argued to be the key leverage point for practitioners who want to design sustainable software-intensive systems. However, existing RE methods and tools do not explicitly facilitate the discussion and negotiation of sustainability-related concerns. This leads to insufficient or onedimensional perceptions of sustainability. In this paper, we discuss our understanding of sustainability and its relationship with requirements. Based on the outcomes of this discussion, we have extended the WinWin Negotiation Model by incorporating sustainability concepts so that the negotiation also includes the ability to consider the impact of requirements on sustainability. Applying this negotiation method in an exploratory industrial case study, we have learned that this approach stimulates the discussion on sustainability and its multiple dimensions. It also allows practitioners to reflect on requirements and their effects on sustainability. However, we have also observed that further in-depth requirements analysis is needed to analyse the long-term effects of requirements regarding sustainability.

“…an 'interest in a system relevant to one or more of its stakeholders' [41]. Considering only the system under design from a technical and economic perspective, the [technical] sustainability of a system architecture, as defined in [42], is clearly a system quality and can be measured and improved by techniques such as evolution scenario analysis, architecture compliance checks, and tracking of architecture-level code metrics. However, in the overall design of the complex socio-technical system that contains this system architecture, sustainability needs to be treated as a design concern of interest to multiple stakeholders that will drive specific capabilities and qualities in the system [6].…”

Abstract-Sustainability has emerged as a broad concern for society. Many engineering disciplines have been grappling with challenges in how we sustain technical, social and ecological systems. In the software engineering community, for example, maintainability has been a concern for a long time. But too often, these issues are treated in isolation from one another. Misperceptions among practitioners and research communities persist, rooted in a lack of coherent understanding of sustainability, and how it relates to software systems research and practice. This article presents a cross-disciplinary initiative to create a common ground and a point of reference for the global community of research and practice in software and sustainability, to be used for effectively communicating key issues, goals, values and principles of sustainability design for software-intensive systems. The centrepiece of this effort is the Karlskrona Manifesto for Sustainability Design, a vehicle for a much needed conversation about sustainability within and beyond the software community, and an articulation of the fundamental principles underpinning design choices that affect sustainability. We describe the motivation for developing this manifesto, including some considerations of the genre of the manifesto as well as the dynamics of its creation. We illustrate the collaborative reflective writing process and present the current edition of the manifesto itself. We assess immediate implications and applications of the articulated principles, compare these to current practice, and suggest future steps.

“…Because the majority of software metrics are code-oriented or design-oriented [6] [7], in a previous work [8] we suggested several criteria to estimate the sustainability of architectural knowledge, which we refine now in Table 1. The sustainability of architectural knowledge can not only be estimated in terms of how much effort we need to maintain the knowledge, but also how stable the decisions are and their longevity as the system evolves.…”

Toward Architecture Knowledge Sustainability: Extending System Longevity

Complex software systems must be maintained for years or decades, and the effort and cost to maintain them are often high, involving continuous refactoring to ensure their longevity in the face of changing requirements. In this article, we introduce the notion of architectural knowledge (AK) sustainability as a new concept to support architects dealing with the evolution of long-lived systems. Architecture sustainability refers to the ability of the architecture to endure over time with the minimum number of refactoring cycles possible. We suggest that sustainability of the AK is a function of how stable the decisions are, and we discuss a set of sustainability criteria and metrics useful to estimate the sustainability of this AK. What is Architectural Sustainability?One of the success criteria for the architecture of a long-lived system is how well it survives the test of time in terms of supporting changes during the life cycle of the system while remaining intact. Many application domains, from complex engineering disciplines like automotive or avionics to information systems among others, demand stable architectures that are based on good, wellunderstood design decisions that extend the longevity of those architectures. However, in many situations software architects and developers struggle to cope with the impact of unpredictable changes (e.g., changes in technology platforms or surprising changes in the organization's business) that need extensive refactoring to implement them. We believe that this is often because architectural sustainability is not considered during the system design.
