Parker Pen Co. is a private company that manufactures writing instruments. Founded in 1888, it was acquired by Gillette in 1993 and then sold to Newell Rubbermaid in 2000. Parker produces fountain pens, ballpoint pens, inks, and refills. Its brands include Parker, Paper Mate, Waterman, and Liquid Paper. In the past, Parker pursued a strategy of rigid centralization and standardization under CEO James Peterson. It began marketing lower-end products more widely. This strategic change failed as it alienated loyal customers and did not account for differences in global markets. The key lessons are that not all products can be marketed uniformly worldwide, and rapid strategic changes can damage brand loyalty
