Evaluation of Scrum-based Agile Scaling Models for Causes of Scalability Challenges

摘要

Agile Software Development (ASD) community have come up with the idea of scaling and created some models/frameworks for large-scale set-up. Despite these models, application of agile methods to large projects remains as a challenging research question for the community. The aim of this work is to evaluate these Scrum-based scaling models (including SoS, Nexus, LeSS, SAFe, Scrum at Scale, DAD, and RAGE) in terms of how and to what extent they are able to provide scaling solutions for the identified causes of challenges in the Agile Manifesto and Scrum Guide, in the context of software development and project management. The study maps the solution proposals of the models for underlying causes of challenges and justify them with three experts. To come up with an evaluation, considering the experts' views, the auditors provide a thorough perspective on models' solutions against to the common pain points underlying the manifesto and guide for scaling. With some exceptions, we see that all of the models try to maintain the pain points associated with scalability in the core of the ASD.
