Not long ago, I worked with a client who was stepping into management for the first time. Terry, a highly regarded marketing associate in a pharmaceutical firm, had just been asked to lead a marketing team. In this new role, she was responsible for directing a group of bright, but inexperienced marketing professionals (most of whom had been her peers) in producing plans and promotions for a small portfolio of globally sold drugs. This required pulling together market data, financial trends, and competitive information — and then working with medical and regulatory professionals, ad agencies, product managers, and country staff to shape the final plans.
