==Overview==
Social network change detection (SNCD)| is a process of monitoring social networks to determine when significant changes to their organizational structure occur and what caused them. This scientific approach combines analytical techniques from social network analysis with those from statistical process control(SPC). SNCD can be used to detect when significant changes occur in a network. In application, it requires the use of statistical process control charts to detect changes in observable network measures. By taking measures of a network over time, a control chart can be used to signal when significant changes occur in the network.SNCD may offer executives and military analysts a tool to operate inside the normal decision cycle. SNCD not predicting change,but rather detecting that a change occurred quickly and making some inference about the actual time of change.For example, before a terrorist commits an attack, there will be a change in the social network as the organization plans and resources the attack. SNCD may allow an analyst to detect the change in the social network, prior to the successful completion of the attack.〔
