8. General discussion and theoretical implications
This work investigates the relationship between design perception and consumer based brand equity formation, composed of three stages — design perception leading to experiential values, which in turn affect overall consumer based brand equity. It also examines the importance of user expertise in altering this relationship. Absence of an attribute-based design perception scale required a scale development effort, which culminates into conceptualization of consumer design perception as five dimensional constructs reflecting visual,functional, kinesthetic, interface and information design, well supported by literature (Garrett, 2003; Noble and Kumar, 2008, 2010; Sonderegger & Sonderegger and Sauer, 2010). Items are generated and validated for each of these sub-dimensions using mixed method approach, involving literature integration, qualitative and three stages of quantitative research. Next, the proposed model which related design perception to consumer based brand equity through experiential value is tested using data from not only the two samples used to develop the scale, but also from a third sample data with a mix of interactive devices, to ensure general validity of the scale as well as the model. Structural model results come out to be robust across all the three samples with strong relationship amongst design perception, experiential value and brand equity. The direct relation between design perception and brand equity is non-significant for all samples which indicates a strong mediation effect by user experience and confirms the importance of experiential consumption as discussed by Holbrook and Hirschman (1982) besides highlighting the role of product attributes and experiences as antecedents in shaping consumer-brand relationship (Keller, 1993). This work also examines the moderating role of user expertise in affecting design derived experiences, as suggested by Zielfe (2002), and proves so for smartphone users but not for the sample with other interactive devices.
