Procuring Accessible Third-Party Web-Based Software Applications for Inclusivity: A Socio-technical Approach

The accessibility of web-based software applications is critical, particularly in tertiary education. This is important given the imperative for inclusivity, driven by the increasing diversity of the student population, including individuals with disabilities. Despite this, the procurement process for Third Party Web-Based Software Applications (TPWBSA) in universities often fails to adequately consider web accessibility standards. This study investigates how universities can enhance decision-making processes related to TPWBSA procurement to improve accessibility for both students and staff. Using a socio-technical systems (STS) framework, we utilise the SEIPS 2.0 model to evaluate and assess accessibility compliance within the procurement process. Through a case study at a single university, we conducted ten qualitative interviews with procurement experts and experienced users (students and staff), followed by thematic analysis to explore current practices in assessing web accessibility. Our findings highlight the potential of the SEIPS 2.0 model to map work systems, processes, and outcomes, offering a structured approach to improving accessibility evaluation in TPWBSA procurement. This research fills a critical gap in understanding how accessibility compliance is addressed in procurement, advocating for the integration of equality, diversity, and inclusion by design as a fundamental aspect of technology-related decision-making in higher education.
