This chapter presents a model of customer-centric strategy implementation based on best practices developed by Vetropack, one of the leading companies in the European glass packaging industry. The company developed its own mix of customer-centric marketing strategies, which are implemented on various organizational levels and include processes such as quality assurance, key account management, customer care, business partnering, and a marketing information system. Although the model developed and case presented are based on some industry specific features, the overall approach could be used as a benchmark for different industries and companies, especially those active in business-to-business markets. As an outcome, combining the theoretical framework and best practice findings, we propose a new approach to customer-centric strategy, which unifies internal and external organizational learning.
