This thesis contains main results from an industrial PhD research in the areas of supply chain strategy, planning, and coordination. It applies the concepts of responsiveness and coordination to reduce mismatch of supply and demand, especially for a volatile and seasonal supply chain. It involves a series of case studies on the process of planning coordination between a toy manufacturer (LEGO Company) and its major European customers (toy retailers).
The thesis presents a plurality of six selected research papers and a main report. These research papers provide case analyses while the main report generalizes their key findings, insights, and implications to theory and practice. The thesis concludes several theoretical frameworks and contributions to the theory of responsiveness and supply chain coordination.
The thesis begins with analyzing four different responsiveness strategies – differentiating products, differentiating retailers, accurate response (with forecast adjustment and premature replenishment), quick response (order-penetration-point relocation and lead-time reduction). These analyses extend the Fisher Model of responsiveness and refine six propositions or principles of responsiveness. The thesis further explains the multi-characteristics of seasonal products in their life cycles and concludes an integrated framework of responsiveness.
For coordination issue, the thesis develops a new bullwhip measure, and then quantifies and explains bullwhip effects in the toy supply chain. It also reveals how information sharing and its favourable conditions influence the bullwhip effects. These results enhance understanding of the coordination problems before coordination processes are initiated.
The cores of this thesis are the observed patterns of coordination processes, behaviour and strategies between the toy manufacturer and three European retailers. These three case studies provide evidences that the toy manufacturer and the retailers followed some particular patterns of planning coordination processes; they also practised some patterns of coordination behaviour during the coordination processes, particularly the behaviour of risk-taking/avoidance, conflict resolutions, and self-interest. All these lead to conclusion of five propositions or principles of supply chain coordination, and the theory of coordination process and behaviour.
Combining the propositions of responsiveness and coordination, the thesis concludes a concept called Coordinated Responsiveness. It finally discusses the main contributions and implications of this research, the reflections on the research process and some future research.
