Xerox Corporation faced declining market share and revenues in the 1970s-1980s as competitors like Japanese firms entered the copier market. In 1982, David Kearns became chairman and introduced the "Leadership through Quality" plan to refocus on customers and quality. This plan helped increase profits and market share. In 1991, Paul Allaire became the new chairman and continued the quality initiatives, resulting in higher customer satisfaction, revenues, and profits. Xerox had a modified matrix organization structure with business and customer divisions to balance product development and customer relationships.
