During the chaos and confusion created in a crisis, it is easy for fear and panic to take over, and this can completely change the way some people handle different scenarios. Planning for these reactions and barriers helps to ensure a successful implementation of Business Continuity and can help to reduce disruption and the time between the incident and remediation.
If you think practically, a Business Continuity Plan is a plan that allows a business to plan in advance what it needs to do to ensure that its key products and services continue to be delivered (technicality: at a predefined level) in case of a disaster, while a DR allows a business to plan what needs to be done immediately after a disaster to recover from the event. So, a BCP tells your business the steps to be taken to continue its key product and services, while a DR tells your business the steps to be taken to recover post an incident.
Your impact analysis, your business continuity strategy and business continuity plans are a part of BCP. Your incident response, emergency response, damage assessment, evacuation plans, etc. are all a part of DR. It makes sense to divide your planning into two parts
- Planning to continue your business operations and
- Planning to recover from disaster situations
If you use these definitions of BCP and DR, you would probably end up having a practical and effective BCMS for your organisation.
