Dr. Arafat Salih Aydiner should be commended for his meticulon efforts to investigate the interrelationships hetween information systems (IS)-related capabilities and their effects on firm performance-based a sample of 204 firms in Turkey. Using the resource-based view (RBV), he develops a set of hypotheses to examine these links, considering the role that may be played by decision-making performance and business-process performance as mediating variables. It is a good reference book for scholars in the field of management information systems (MIS), managers, policymakers, and graduate students. It is a very good addition to the IS literature on major emerging countries such as Turkey. Dr. Aydiner contributes to the IS literature in a number of ways. First, specifying IS capabilities with resources and competencies enables the use of the RBV to better explore the strategic value of IS. Second, a new serial multiple mediator model is designed to consider the influence of decision-making performance and business-process performance on the relationship between IS-related capabilities (i.e., infrastructure, human resources, and administrative) and firm performance. It is envisaged that the adoption of this approach creates a distinct epistemology for organizations to have a strategic IS perspective. The book contains a useful bibliography.
