Agile elicitation of scalability requirements for open systems: A case study
Brataas, Gunnar; Martini, Antonio; Hanssen, Geir Kjetil; Ræder, Georg (Peer reviewed; Journal article, 2021)Eliciting scalability requirements during agile software development is complicated and poorly described in previous research. This article presents a lightweight artifact for eliciting scalability requirements during agile ... -
Agile Scalability Engineering: The ScrumScale Method
Brataas, Gunnar; Hanssen, Geir Kjetil; Herbst, Nikolas; van Hoorn, Andre (Peer reviewed; Journal article, 2019)While agile methods have had a great uptake and impact in software engineering, managing non‑functional qualities still seems to be a challenge. We focus on the scalability of software systems and how this critical quality ... -
Agile Scalability Requirements
Brataas, Gunnar; Fægri, Tor Erlend (Chapter, 2017)Many software organisations struggle to provide appropriate levels of scalability in their software systems. Agile development rests on pragmatic and value-centred approaches to requirement capture that allows customers ... -
