Development and implementation of effective marketing strategies during various stages of product life cycle in the pharmaceutical industry are critical to an organization's successful performance in the marketplace in the 21st century. Guided by the general systems theory developed by Bertalanffy and the evolutionary systems theory developed by Laszlo and Laszlo, the purpose of this single case study was to explore best practices among marketing managers within pharmaceutical companies related to marketing strategies during various stages of product life cycle. Data were gathered via semistructured interviews with 3 purposefully selected managers who have successfully developed marketing strategies in a central Ohio pharmaceutical company in business for more than 10 years. A review of secondary data included company documents, such as annual reports, news releases, and websites, in addition to government databases. Member checking was conducted to ensure accuracy of the interpreted data and trustworthiness of the research findings. Yin's 5-step process and thematic analysis were used to analyze the data. Four themes emerged from data analysis: marketing function, product life cycle phases, factors influencing the decision-making process, and strategic activities in executing business strategies. Findings may have implications for positive social change such as assisting organizational leaders to understand the challenges and business practices in implementing marketing strategies to successfully deliver products that improve patients' health.
