This study identifies key factors required to successfully change a mining organization's culture to that mandated by a continuous improvement (CI) philosophy. Guided by a change-oriented model of CI implementation and the Malcolm Baldridge criteria, a survey was conducted involving mining firms operating in North America with annual revenues over $100 million. Twenty-four firms participated and resulted in 268 usable questionnaires. A principal component factor analysis followed by linear regression revealed that four factors accounted for success in implementing CI; employee involvement was the most important one. This dominant factor proved to be complex and had elements of the context of change (e.g., acceptance of company goals), the content of change (teamwork, new ways of working, and supportive HRM policies), and the process of change (leadership and access to information). Other predictors included, in order of importance, corporate presence, customer-oriented strategy, and adoption of practical goals. The article concludes with a discussion of employee involvement and the trend toward a productivity gap, with firms pursuing CI in the lead.
