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, we 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. These needs are captured through the accessibility, usability and functional requirements of the system in the requirements analysis phase of the life cycle model.
