Efficient and effective processes and knowledgeable employees separate high-performing organizations from average or low performing organizations. In this paper, we develop a five-step method to tune IT Service Management processes by focusing on the knowledge needs for each role and identifying the employee who possesses the needed knowledge. This five-step method employs a Dynamic Network Analysis (DNA) model that includes three classes, Persons, Roles, and Knowledge, and four important relationships between and within these classes.
