Research aim and objectives
Research Aim
Research Objectives
To couple product and design process knowledge evolution to support design development.
To identify the gaps in design knowledge research area To obtain requirements from industry To reveal coupling mechanism of product and design process To reveal the phenomenon of dynamic evolution between the
product and design process To develop the coupling model of evolutionary artefact and design
process knowledge To evaluate the model
Research methodology
Post-positivism
Triangulation
• The reality is multiple, subjective, and mentally constructed by individuals• Design characteristics• Multiple perspectives
• Literature, Industry design process documents• UG & PG students design projects• Industry design practice
Data source triangulation
• Model development• Model evaluation Theory

Literature review of design product knowledge and design process knowledge modelling
Product lifecycle knowledge collection through working along PLM
4th and 5th year undergraduate students design projects recording
Future work
• To finish building the coupling model of product and design process based on student design projects and literature;
• To complete the coupling model by analysing current data
• To evaluate the model– To obtain and analyse protocol data of design
process by working alongside experienced designers in Airbus
– To obtain and analyse postgraduate students design process data
• To finish the thesis writing
