Causal and exploratory associations between manufacturing outsourcing and innovation performance in the UK furniture industry Jeff Readman A thesis submitted in partial fulfilment of the requirements of the University of Brighton for the degree of Doctor of Philosophy February 2014 The University of Brighton Abstract While the cost advantages associated with outsourcing are accepted, the impact that outsourcing may have on innovation performance is ambiguous. One perspective suggests that firms outsourcing low value-adding activities will achieve higher innovation performance (that is, better designed or more technologically advanced products or more substantive process improvements) than firms that perform these activities in-house. Another view holds that firms that outsource high value-adding activities may have lower innovation performance than those firms that perform these activities in-house. While these two positions are not contradictory, neither are they complimentary. Moreover, superior innovation performance can be achieved through the effective use of innovation, or dynamic, capabilities. The relationships between outsourcing and innovation performance in the UK furniture manufacturing industry are investigated in this study. A mixed-methods approach is employed, which includes three case studies and a survey of 66 manufacturers. Industry analysis and case interviews document the critical value added activities in the industry and contribute to the formulation of a questionnaire. Non-parametric statistical techniques are applied to test the survey results. This study contributes to the discourse by showing that innovation performance is affected by outsourcing decisions. Outsourcing peripheral activities has no impact on innovation. However, performing core activities has a positive impact on innovation. The findings support the previous documented relationship between capabilities and product and process innovation by revealing enablers, which are particular to the furniture industry. Interestingly, there is a strong correlation between customer-focus strategies and innovation performance. Furniture manufacturers are attuned to customer design preferences through critical buyer channels. Other key findings highlight the association between firm size and innovation and the importance of innovation capabilities for medium size firms. The rational for investigating one industry is conducive to interrogate organisations performing similar business activities. The findings are relevant not only to the UK furniture industry but also to other traditional manufacturing industries, which demonstrate similar innovation performance and outsourcing patterns. 2 Table of Contents List of Tables 9 List of Figures 13 Chapter 1.
