# Towards an Architectural Perspective for Sustainability: Bundle the Needs from Industry

## TL;DR

This paper proposes a new architectural perspective framework to integrate sustainability concerns into software design, supported by literature review and expert insights, aiming to guide architects in addressing sustainability effectively.

## Contribution

It introduces a revised notion of architectural perspectives specifically tailored for sustainability, filling a gap in structured guidance for architects.

## Key findings

- Relevance of perspective elements confirmed in practice
- Implications for industrial adoption identified
- Framework supports addressing sustainability throughout design

## Abstract

Sustainability is increasingly recognized as an emerging quality property in software-intensive systems, yet architects lack structured guidance to address it effectively throughout the software design phase. Architectural perspectives-an architectural knowledge artifact composed of concerns, activities, tactics, pitfalls, and checklists-offer a promising approach to tackle such emerging quality properties across architectural views and are also independent of architecture frameworks and industry contexts. In this paper, we present a sustainability perspective vision, i.e., a revised notion of architectural perspective meant to be filled with its own elements to target sustainability concerns. We formulate our sustainability perspective vision through evidence from applying snowballing to seminal literature and from conducting a focus group with experts in the field. Our findings confirm the relevance of the different perspective elements in practice and highlight implications for shaping a sustainability perspective that meets industrial needs.
