It's entirely for teaching purposes. I've found over the years that I've been teaching this that the majority of folks attending a class about performance testing are very heavily biased toward one perspective or the other. Separating the categories seems to help folks recognize their biases and adjust accordingly.<br /><br />The fact is that once you (or your team) recognize and adjust to whatever bias you may (or may not) have, there is no real reason to have 5 "buckets" instead of 3. The points that matters *most* to me are the following:<br /><br />- Recognize the difference between negotiable and non-negotiable items (whatever you call them).<br />- Remember to consider both the system as a whole (i.e. End-User) and the pieces that make up the system.<br />- Consider that not all of the reasons for conducting performance testing may involve "pass/fail" criteria.<br /><br />I'm confident that you already get that, Alex, and that this is just reinforcement. Like I say, I'm trying really hard these days to make key concepts easy to both teach and learn for folks who haven't been living and breathing this stuff for (probably too many) years like you and I have.<br /><br />Thanks for the note - that was a really good question to have answered here!Anonymoushttps://www.blogger.com/profile/11678206907629678117noreply@blogger.comtag:blogger.com,1999:blog-5166487924843918388.post-79413324395589093122011-09-26T12:31:43.029-04:002011-09-26T12:31:43.029-04:00What is the principal difference between 1)perform...What is the principal difference between 1)performance goals and performance targets 2) between performance requirements and performance thresholds? They sound very close to me. Do we actually need five groups here? For me, first three look enough from the practical point of view. What I am missing?<br /><br />Regards,<br /><br />AlexAlex Podelkohttp://www.testingreflections.com/user/view/67noreply@blogger.com
