Is your business continuous?
CIOs
should use a business continuity plan to make their organisations less susceptible
to outages. Here are a few steps that will go a long way in ensuring continuous
operations and productivity in the workplace. by Lakshman Narayanaswamy
Business continuity is about making your business resilient
to events that are disruptive and affect the goals of your business. Taking
steps to keep your business continuous does not have to be complex and fraught
with options and possibilities.
In this article, we introduce the methodology behind business
continuity planning and aim to simplify what it takes to make your business
more continuous, and how to derive the biggest bang for the buck from your investment
in business continuity.

Talking the talk
Business continuity and Disaster Recovery (DR) are two terms
that are used interchangeably. DR is an older term that is used for recovery
of IT systems. It also connotes a reactive approach to managing recovery. Business
continuity is the current usage that connotes a broader scope then just IT.
It also suggests a proactive approach in keeping the business available.
The approach to business continuity is common sense, just
like having a spare tyre in the car to avoid disruptions from nails on the road,
and a second gas cylinder in the kitchen to compensate for delivery delays.
Business owners and management must not dismiss business
continuity as an exercise only for the top 100. According to The New York Times
45,000 small businesses ceased to exist after the Sept 11 attack on the World
Trade Center as they could not absorb the loss of income and the operational
logistics of being around the disaster site.
Know thy business
An effective start to making your business more available
is to understand the various activities that connect a customer requirement
to its fulfillment. The goal of this exercise is to identify activities that
are critical to the running of the business.
Once critical activities are identified, the inputs, outputs
and various dependencies must be understood. As an example, in a manufacturing
enterprise, the goods production plant is critical for the viability of the
business. A key dependency of the manufacturing process could be the ERR system
that runs all the machinery in the plant.
The critical activity could be an IT application, for example,
ATOM banking and information in a banking enterprise.
Critical to business
When is an activity critical to the business? When the loss
of or inability to provide for the activity damages the business. The loss or
damage can be a financial impact or a qualitative measure like loss of reputation
and customer trust. It is very useful to understand the implication of loss
and quantify it.
As an example, banking industry figures suggest that thirty
minutes of downtime can translate to a loss of up to Rsv 2 crone. Based on the
impact of downtime, the management can determine recovery objectives. A key
recovery measure is Recover Time Objective (RTF), the amount of time the business
has before it must be available.
Having identified activities that are critical to a business,
the next step is to explore the vulnerability of the business to various kinds
of events.
Understand your business vulnerabilities
Tsunami and earthquakes make headlines and draw attention,
but experience tells us that unplanned events and acts of God account
for less then five percent of business downtime. Everyday events like software
and hardware errors, patch upgrades, configuration changes, network outages
and power failure cause over 80 percent of business outages.
A time-tested way to understand your business vulnerabilities
is to list all possible events that may occur. These include acts of God,
civil amenity failures, and people- and technology-related events.
For example, a list of events to consider are:
- Fire, flooding, building not accessible
- Power outage, A/C breakdown, water sprinklers going
on accidentally
- Telephone line down, computer hardware malfunction,
software crash
Against each event in the list, we assign probabilities of
occurrence and the potential impact of the event on the business. The management
then makes a decision on the kind of events that the business is going to protect
against and have a continuity plan for.
By identifying critical business functions and events to
protect against, the business continuity plan can address how the critical functions
can be made available when events occur.
IT DR plan
IT solutions are an integral part of an enterprise and are
often critical to the running of a business. Continuity of IT applications is
complex and has several components that must work together. A common mistake
is to have data replication in place and assume it is a DR plan for the application.
This is far from true.
Replication is one ingredient of a successful IT DR plan.
The ability to recover data, ensure application-level data consistency, failover
the application and redirect clients of the application is essential for successful
IT DR. A very critical part of a successful IT plan is regular testing of the
failover capabilities of the solution. Regular test drills ensure that the DR
solution will work for you when you need it.
Business continuity is a process and not a technology solution.
It is not a one-time effort. A plan that will work for you is one that involves
the right people, has processes in place and has IT and infrastructure support
to keep the business going.
An effective first step is to invest in a plan that gives
you the information you need to make decisions. Also, rather than plan for the
whole enterprise in a single exercise, it is effective if each department has
its own plan. This can then be tied together from an enterprise point of view.
Investment in a secondary site need not be just an insurance
policy. Many enterprises have been successful in offloading several offline
activities to a secondary data centre. Data warehousing is a good example of
an activity that can be done at the secondary site.
In summary, business continuity is no longer an option, but
a necessity. A successful plan has people, process and infrastructure to keep
critical functions of the business available.
