|
<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> |
