<ol><li><img src="./delta.gif" alt="Start of change" /><span> <span class="uicontrol">Develop a list of the major services and
|
||
|
|
solutions that your system provides.</span> Your system exists so that
|
||
|
|
end users and solutions can accomplish tasks that are critical to the operation
|
||
|
|
of your business. The systems provide solutions to a business function. If
|
||
|
|
the system is unavailable, the business function cannot be completed or is
|
||
|
|
significantly degraded to the point of causing the business lost revenue or
|
||
|
|
increased expenses. </span><img src="./deltaend.gif" alt="End of change" /></li>

|
<li><img src="./delta.gif" alt="Start of change" /><span> <span class="uicontrol">Assess how much it costs you when these
|
||
|
|
services are unavailable.</span> Each application or service has a direct
|
||
|
|
affect on business functions. You need to determine how these business functions
|
||
|
|
would be affected and what would be the overall cost to your business.</span><img src="./deltaend.gif" alt="End of change" /></li>
|
||
|
|
<li><span> <span class="uicontrol">Look at direct costs versus indirect costs.</span> Direct
|
||
|
|
costs are losses that can be traced directly to a system being unavailable.
|
||
|
|
Indirect costs are those that are incurred by another department or function
|
||
|
|
as a result of an outage.</span></li>
|
||
|
|
<li><span> <span class="uicontrol">Consider tangible costs versus intangible costs.</span> Tangible
|
||
|
|
costs are those that can be measured in currency. However, there are other
|
||
|
|
costs that are not measured with money, such as market share, lost opportunity,
|
||
|
|
and good will.</span></li>
|
||
|
|
<li><span> <span class="uicontrol">Analyze fixed costs versus variable costs.</span> Fixed
|
||
|
|
costs are those that result from a failure and are the same, regardless of
|
||
|
|
the length of the outage. Variable costs are those that vary, based on the
|
||
|
|
length of the outage.</span></li>
