There are many, many metric used in software testing. Do a search on this site for "metrics" to see many discussions on this topic. Metrics are often used to drive process improvement in organizations.
It is up to each organization to determine the best metrics to use. Some will apply to the work you do and others won't. I cam from a company that tracked almost no metrics and am now with a company about to achieve CMMI maturity level 3 with an eye towards level 5. I can tell you that the metrics we collect are very useful in driving improvement.
I am not aware of metrics in QA! - and the communication did not mention the kind of metric
As of yet, the following is what I have gathered
1. There are many kinds of metrics
2. I should attempt to figure out why this change is required!
Would you be able to throw me some metric related termninology and which metrics maybe considered for a QA Business Unit or a tester
I hope, this has nothing to do with the evaluating the performance of a tester with the number of defects raised.
Unfortunately, I am not in a position to "ask" more about this from the business leader, however if I would be aware of the kind of metrics which are related for a QA unit, then I might be able to understand the "would be coming" changes better!
Ok, so we know
- your leader wants to "create a metric-oriented culture"
- you don't know what your leader means by that
- for some reason, you can't ask what it means
- you don't know anything about metrics in QA
I hope at some point your leader decides to communicate more and actually give you a hint about what they are trying to achieve and how. We can only guess - every company does it differently.
But if not, you'll at least certainly be told what data you are supposed to gather.
And eventually you'll learn if these metrics are to be used to evaulation individual performance or not. (And if they are, you'll quickly learn how to produce the metrics that will get you a good performance evaluation. Gaming the system usually isn't difficult.)
Your best bet now is to search here on QA Forums and on Google for "QA metrics". You'll find many, many discussions about specific metrics/techniques/approaches and if they are good or bad in each person's opinion.
None of these may directly relate to your situation, but eventually you'll find out for sure.
