The book "Penitentiary Violence: Model of Information Management and Analysis" deals with a method of analysis that arises from the experience of analysing the violent events that occur in Chilean prisons, mainly the events of fights and aggressions between inmates. The model shows the relevance of systematising the information and designing a model of analysis that makes it possible to know the violent events and identify them precisely, in order to guide the relevant and focused actions of the prison administration. Along with this, the figure of prison managers is proposed, for those who administer and make decisions in prisons, highlighting the scientific knowledge of management to direct the prison units as well as the central management levels.
