In developing software systems, software engineers use software development life cycles such as the waterfall, prototyping or spiral model. Whilst these life cycles ensure that the system meets the needs of people without disabilities, the needs of people with disabilities are often overlooked thus resulting in systems that are inaccessible and unusable to them. In this paper, the authors propose a disability-aware software engineering process model which considers the needs of people with disabilities, hence improving accessibility and usability of the designed system.
