ON

BUSINESS

CONTINUITY

PLAN

AND

MAXIMUM

TOLERABLE DOWNTIME AND HOW IT AFFECTS THE ORGANIZATION’S
BUSINESS
1) Definitions
For any business’s processes, an organization needs to define its Business Impact
Analysis (BIA), so after that for each process in the BIA the organization needs to
determine the Maximum Tolerable Downtime (MTD)
...
The main purpose of BIA is to identify which processes and
systems are the most critical to the survival of an organization
...

The purpose of BIA is not only identifying critical processes and their downtime but
also to determine what the recovery method should be for each damaged process [1]
...
A business process has also been defined as a set of
activities and tasks that, once completed, will accomplish an organizational goal [2]
...

Another

terms

for

MTD

is

Maximum

Tolerable Period of Disruption (MTPOD) and
Maximum Allowable Downtime (MAD)
...
MTD variations depends on importance of
can differ from a process to another

processes [3]

depending on the process and how important it is for the business and how critical this
business operations might become if that process is unavailable
...
Business
functions associated with customer service and billing often have the shortest
maximum tolerable downtimes [1] [4]
...

It is important to define each process and function and how important it is to the
business operations in which it will help determine the maximum downtime for those
processes depending on the criticality they provide to the organization’s objectives
and goals [5]
...
For example, if a function is
categorized as mission-critical for the business or high priority, then it would likely be
assigned the shortest MTD [5]
...

By applying a good BIA, an organization can determine more effective recovery
objectives which can help in restoring business operations, when a process fails, before
reaching the specified MTD of that process
...
The higher the criticality, the shorter the maximum tolerable downtime is
likely to be
...
Therefore, MTD = RTO + WRT


Figure 2
...
It is typically one segment of the MTD
...
This is the time you
will have to get systems back up and running
...
If your MTD is three days, Day 1 might be your RTO and
Days 2 to 3 might be your WRT
...

A correct and precise plan to determine and handle the MTD for the disruption of a
business function is required, otherwise, you will miss your MTD requirements and
potentially put your entire business at risk [5]
