<p>On a previous life, to understand how a system behaved, I added a ton of
|
||
|
|
metrics: how fast things were going in, how fast things were going out, how
|
||
|
|
many things were in the middle, how many the job processed... Not doing it so
|
||
|
|
makes me feel... naked.</p>

|
|
<p>Monitoring your project performance give you a really good view of how a
|
||
|
|
system is behaving. Is the speed going down? Is the system taking longer to
|
||
|
|
process an input? Are no inputs being processed?</p>
|
||
|
|
<p>If you have this kind of information, you can check what is going on in the
|
||
|
|
system and understand why. Is it normal? Did a change around the system (the
|
||
|
|
other system that produces the input, the system that consumes in the output)
|
||
|
|
affected the results?</p>
|
||
|
|
<p>If you're not measuring, you'll have no idea.</p>
|
||
|
|
<p>Also, "If you can not measure it, you can not improve it", as Lord Kevin said.</p>
