This article focuses on how to implement strategies successfully through projects. Based on the literature we propose measures for successful management of strategic intentions in a multi-project context. Empirical survey of 288 organizations is used to analyze practices that organizations use in managing development projects. Correlations between management practices and success measures are examined and the success factors determined. Several success factors are found related to both single and multiple project management. In addition, the linkage between strategy process and project management, as well as the availability of high-quality information are identified as success factors. © 2005 Elsevier Ltd and IPMA.
