It’s very important when starting working on IT project to define the right scope for your mission.
I was working these days on DR (Disaster Recovery) project and I have been talked to many colleagues from different departments: Business unit, quality assurance, Audit department and of course IT department.
What I have remarked when explaining the need for a Business continuity plan is that every concerned person see only his related scope and did not have the attitude of general or global vision to the scenario.
In fact, when dealing with such kind of project, it’s important to forget your current job and see the problematic from a general perspective.
It’s sure for all of the organization that any business process is based usually on business Application and that each application need resources and infrastructure to run and turn up.
Defining the relationship between your business applications and your IT infrastructure is an important step when starting a business continuity project or more specifically a Disaster recovery project.
Important organizations, especially telecommunication ones, usually we talk about three important units:
It’s important to know that the customer expectation stays the same even after a disaster was occurred.
From a concept side, it’s important to understand the difference between 3 points:
- High availability
- Disaster recovery
- Business continuity
High‐availability techniques are about preventing the everyday failures that cause
Downtime (network card failure, disk crash…)
A quick search on the Internet will reveal a number of definitions for disaster recovery. One that I like is that it is the processes used to return a business to a normal operating state
after the occurrence of a catastrophic event.
Disaster recovery, as a term, is normally applied to the recovery of an IT system, or infrastructure, after a disastrous event has struck.
However, you need to think about the difference between disaster recovery and business continuity.
Business continuity and disaster recovery are confused for each other even more than
disaster recovery and high availability. In simple terms, the Business Continuity Plan (BCP) is the processes and procedures that will be followed to enable the business to function in a reduced, or preferably normal, capacity.
It is involved with a large number of areas including:
- Office space and furniture
- Business process systems
- Procurement of replacement equipment
- Possibly even the hiring of new staff
