High Quality Content by WIKIPEDIA articles! In a computer science system or network, a runbook is a routine compilation of the procedures and operations which the administrator or operator of the system carries out. Runbooks are often used in information technology departments of commercial companies and NOCs as a reference for system administrators. Runbooks can be in either electronic or in physical book form. Typically, a runbook will contain the procedures to begin, stop, and supervise the system. It can also contain descriptions for the handling of special requests and of contingencies. An effective runbook will allow other operators, with prerequisite expertise, to effectively manage and troubleshoot a system. Through runbook automation, these processes can be carried out using software tools in a predetermined manner.
