This paper uses the paradigm of e-accessibility, and in particular the application of publicly available selfservices
in order to demonstrate and discuss the power of a Systems Thinking perspective in Design, and
more specifically in the design of services. Our aim is to present some justification as to why employing
systems thinking can help designers to identify and acknowledge holistically the dimensions of problem
space for which they are required to design. The richness of the approach will be discussed, through
some theoretical tenets of systems thinking, such as the use of the emerging properties, and the law of
requisite variety, notions of second order cybernetics etc. in the conceptualisation and praxis of design
