What does prior research1 claim a design
process2 communicating methodology should
entail?
How does implementing the theoretically founded
methodology impact design process efficiency
and effectiveness?
1. Research Fields of Design Theory, Knowledge Management, Human
Computer Interaction, and Process Modeling.
2. Building design processes from concept design to construction
documentation.

Sir Ove Arup founded his practice in London in 1946 based on a belief in ‘total design’
— the integration of the design process and the interdependence of all the professions
involved, the creative nature of engineering, the value of innovation and the social
purpose of design.
