However, these approaches have focused on specific quality attributes rather than more general non-functional aspects established by standards such as ISO/IEC 25010 for software evaluation and quality. Thus, developing specific software products by selecting features and at the same time measuring the level of compliance with a stan-dard/guideline is a challenge. In this work, we present the definition of an accessibility VM based on the web content accessibility guides(WCAG) 2.1 W3C recommendation, to obtain a quantitative measure to improve or construct specific SPL products that require to be accessibility-aware. This paper is specially focused on illustrating the experience of measuring the accessibility in a software productline (SPL) in order to check if it is viable measuring products and recommending improvements in terms of features before addressing the construction of accessibility-aware products. The adoption of the VM accessibility has been putted into practice through a pilot case study, the MOOC (Massive Open Online Course) initiative of the Universidad Técnica Particular de Loja. The conduction of this pilot case study has allowed us to illustrate how it is possible to model and measure the accessibility in SPL using accessibility VM, as well as to recommend accessibility configuration improvements for the construction of new or updated MOOC platforms. date_type: published date: 2019-09 volume: B pagerange: 114-121 event_title: SPLC 2019: 23rd International Systems and Software Product Line Conference event_location: Paris, Francia event_dates: 00/09/2019 event_type: conference id_number: 10.1145/3307630.3342416 institution: ETSI_Sistemas_Infor department: Sistemas_informaticos_2014 refereed: TRUE isbn: 978-1-4503-6668-7 book_title: SPLC '19: Proceedings of the 23rd International Systems and Software Product Line Conference official_url: http://kishi-lab.sakura.ne.jp/splc2019/ comprojects_type: MINECO comprojects_type: MINECO comprojects_type: MINECO comprojects_code: TIN2016-79726-C2-1-R comprojects_code: RTI2018-101204-B-C22 comprojects_code: TIN2017-90644-REDT comprojects_acronym: CROWDSAVING comprojects_acronym: OPHELIA comprojects_title: Arquitectura adaptativa para crowd-sensing de comunidades eficientes comprojects_title: Optimización de Servicios Basados en Conocimiento Usando Aplicaciones Basadas en Servicios comprojects_title: Red en nuevas tendencias en arquitectura software y variabilidad citation: Rodriguez Morales, Germania Del Rocio and Pérez Benedí, Jenifer and Benavides, David (2019).
