5. Research aim and objectives Research Aim Research Objectives To couple product and design process knowledge evolution to support design development. TT o identify the gaps in design knowledge research area TT o obtain requirements from industry TT o reveal coupling mechanism of product and design process TT o reveal the phenomenon of dynamic evolution between the product and design process TT o develop the coupling model of evolutionary artefact and design process knowledge TT o evaluate the model

6. 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 triangulation Content analysis Case study Protocol study Methods triangulation

7. Research design Research Process Affect Line Literature Review Airbus design practise & PG student project Outcome Research Problem* - To explore design knowledge coupling Design Product, Process Model Review Documentation - Thesis* Design Problem* - Design knowledge Hypothesis - Evolutionary knowledge coupling model* Evaluation: Refined Model* Airbus PLM training & UG Student Project Industry interview & documents analysis Data source Knowledge Coupling Review Aim and Objectives * Checking and reflection are needed
