|
|
<div><p>Different business needs require different performance management
|
|
strategies. Here are three basic business models and their suggested performance
|
|
management strategies.</p>
|
|
<div class="section"><p>Developing a good performance management strategy will help you
|
|
manage your system's performance. Your performance management strategy depends
|
|
in a large part on the amount of time you can afford to spend managing performance.
|
|
If you are working with a small company, you may be managing many different
|
|
aspects of your business and cannot devote many hours to managing performance.
|
|
Many large companies employ performance specialists to keep their systems
|
|
tuned and running effectively.</p>
|
|
<p>For determining a basic performance management
|
|
strategy and for identifying which performance applications to use, classify
|
|
your company in one of three categories: small business, mid-sized business,
|
|
and large business. The business resources vary for each size, and your management
|
|
strategy will vary accordingly.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Small business</h4><p>A small business most likely has
|
|
fewer resources to devote to managing performance than a larger business.
|
|
For that reason, use as much automation as possible. You use PM <span class="keyword">iSeries™</span> to
|
|
have your performance data sent directly to IBM<sup>®</sup> where it will be compiled and generated
|
|
into reports for you. This not only saves you time, but IBM also makes
|
|
suggestions to you when your <span class="keyword">iSeries</span> server
|
|
needs an upgrade.</p>
|
|
<p>The following is a list of recommended performance
|
|
applications for a small business:</p>
