With increased competitiveness, increased pressure to exploit scale advantages in operations and with increasing customer demands of availability, adaptability and responsiveness, supply chain management has become a cornerstone in modern business administration. One concept that has attracted attention from scholars and practitioners is the concept of supply chain agility. This paper concerns the development of responsive supply chains and presents a case study concerning a Swedish global retail firm. The purpose of the paper is to explore the relationship between supply chain transparency and the agile supply chain. We also aim to explore the challenges that firms face when striving to attain transparency and implementing response-based supply strategies in buyer-supplier relationships. Our findings in this research project in progress points at the critical role of a system handing real-time information. Our study also corroborates the view that it is perhaps more realistic to discuss agility as a current status and something that is continuously developing, rather than as a static property of a supply chain.
