Business impact assessments
Our approach to business continuity planning is one that is driven by recovery of critical business services, including the medium and long-term loss of systems and data.
Business Impact Assessments are carried out on Activity Business Cases (ABCs). An Activity Business Case is the budget and business planning and monitoring process for our key activities.
It covers operational and strategic activities, core services, capex investment, and government initiatives.
The Business Impact Assessments are to ensure that critical services, along with their supporting activities and resources, are identified and documented. Identification of critical services are risk-based:
- Identification of Activity Business Case activities supporting resources.
- Mapping the workflow of the identified Activity Business Case activities and processes, ensuring these consider supporting resources.
- Assess the impact on the organisation in the event of Activity Business Case activities being disrupted.
The recovery time objective (RTO) and maximum tolerable period of disruption (MTPD) are included in line with the scoring results of the Business Impact Assessments (impact categories have been scored and given a Red, Amber, Green rating).
These scores are then reviewed and, where necessary, will be discussed with the relevant Activity Business Case owner to outline activities which require the development of a Business Continuity Plan (BCP).
The maximum tolerable period of disruption and recovery time objective will be recorded within the Business Continuity Plans to enable owners of the plan and senior management to understand the information recovery requirements of the relevant Business Continuity Plan.
Once maximum tolerable periods of disruption and recovery time objectives have been identified and documented, recovery information within each Business Continuity Plan is cross checked against actual recovery capabilities set out in the IT disaster recovery plan to ensure that this is realistic and can be feasibly implemented in the event of a disruption.
Incident response plans contained within the respective Business Continuity Plans will be updated to focus specifically on the various dependencies and personnel that exist within the Activity Business Case, rather than being based on example scenarios.
The Business Continuity and Resilience Steering Group will provide oversight of the process for performing Business Impact Assessments and updating Business Continuity Plans.
