How Do Investors Evaluate Business Continuity Management （BCM） Disclosures in Emergency Situations？ Evidence From the Great East Japan Earthquake

This study examines economic effects of business continuity management （BCM） disclosures through analyzing changes in shareholder returns in the wake of the Great East Japan Earthquake. The author examined differences in the recovery of share price between disclosing and non-disclosing corporations. The results show that the cumulative average abnormal returns （CAARs） of disclosing corporations recovered faster than non-disclosing corporations. Then, the author examined differences in the recovery of share price between developing and non-developing corporations. The results show that there is no statistically significant difference in the recovery of share price between developing and non-developing corporations. Finally, the author examined the differences of BCM between disclosing and non-disclosing corporations. The results suggest that BCM or business continuity plan （BCP） disclosing corporations have a broader coverage of the BCP, more appropriate procedures for responding to emergency situations, more effective training of the BCM, and more mature BCM systems than non-disclosing ones.

Business Continuity Management,Operational Resilience,and Organizational Resilience:Commonalities,Distinctions,and Synthesis

The concepts of business continuity management,operational resilience,and organizational resilience each refer to actions that businesses and organizations can take in anticipating and responding to disruptions.However,the existing definitions and usages are difficult to differentiate due to overlapping objectives,implementation processes,and outcomes.This article examines definitions and approaches for these three concepts and suggest a framework to operationalize methods and tools relevant to each.These definitions emphasize three dyads:risk versus resilience;organizational processes versus assets;and normal operating conditions versus crisis conditions.Using these dyads to differentiate the concepts of business continuity management,operational resilience,and organizational resilience can support planners in clarifying objectives and identifying which approach will be most beneficial as businesses or organizations plan for and encounter disruptions.This article evaluates these concepts by examining illustrative examples of disruptions and responses.

Analysis of the ITIL Mapping with COBIT over the Business Process Continuity Management

Planning and implementation as well as increased control over the Business Continuity Management （BCM） is a complex task in the company requiring adequate resources. BCM aims to reduce risks and develops plans for restoring business activities if they are interrupted by a disaster. The purpose of the paper is to analyze and describe two standards, Information Technology Infrastructure Library （ITIL） and Control Objectives for Information and Related Technology （COBIT）, especially their mapping for the improved planning and implementation of the BCM as well as the increased control over the BCM activities. COBIT is used more as a management framework, providing management tools, such as control objectives, metrics and maturity models in order to complement the control framework. ITIL includes process steps and tasks because it is more oriented towards IT processes （process framework）, defining the best practice for IT service management. Within this mapping, ITIL processes may be used to achieve and demonstrate compliance with COBIT control objectives for BCM process.
