Study on Organizational Response Management to System Failures

Critical infrastructures are interdependent, and among them, information and telecommunications tend to have a wide range of influence in that they are responsible for the neural functions of other critical infrastructures. Therefore, reducing the occurrence of information and communication failures is a highly important issue for maintaining a safe and secure social life. To solve this problem, in addition to improving system reliability and preventing system failures from occurring, emphasis is being placed on the concept of reducing the magnitude of damage and the time required for recovery, based on the assumption that system failures will occur. Specifically, companies and local governments have embodied this concept in BCP (Business continuity planning) and BCM (Business continuity management), which are mechanisms to prevent the suspension of operations. The information system has been conventionally considered to be a "business continuity plan" or "business continuity management. In the past, there have been examples of preparing emergency manuals for information systems as a way to deal with system failures. However, there was a possibility of ad hoc management in the event of unexpected situations, such as deviations from the assumed plan. This paper discusses how to improve the management of emergency response after a system failure by introducing the concept of project management. The effectiveness of the proposed method will be examined through case studies of system failures.
