Software pattern is a general reusable solution to a commonly occurring problem within a given context while software development and management. Among various software patterns, organizational patterns are known as the basis for Agile software development movement, especially for Scrum and Extreme Programming. Patterns usually form a network having relationships among them to support users understand and utilize patterns efficiently and effectively. However little is known about the nature of such pattern networks, such as how are organizational patterns different from other patterns from the viewpoint of centrality. To clarify such characteristics of pattern networks and organizational patterns, we mine a network consisting 285 patterns from an existing world-largest online pattern repository called Portland Pattern Repository (PPR). By applying network analysis techniques to the mined network and careful review of the result, we revealed several interesting characteristics of the pattern network and organizational patterns.
