Design
Design development is the last stage of the working
model. It is here, after the themes and insights have been
developed and evaluated that a designer can continue
working towards a designed outcome. It is also presented
here that scenarios continue to be used throughout the
design development process to derive problem
descriptions, future predictions, concept generation,
requirements analysis and detailed system design (Lim
and Sato, 2005) as each of these scenario uses are useful
to the design process.
