Usually, if clients find it difficult to calculate DDP per release, we recommend that organizations calculate a rolling twelve-month average. This leaves out some testing bugs that would be included for releases still generating defect reports in production, but it also leaves out some production bugs for releases that were more-recently put into production. Thus, the error tends to average out. I hope that is helpful? Regards, Rex Hi Alejandro–

In my case, my company releases software quarterly, but because of the nature of our business, users utilize 100% of our suite of web applications' features in the course of an entire year (so for example, a bug inadvertently introduced could potentially be found several months later). We used to calculate DDP for every release, but as we move more into Agile practices (featured-driven-development), we are starting to have parallel releases because smaller features are finished early and are deployed to production while at the same time the quarterly (larger) release is being worked on. So we can no longer calculate DDP the same way because the sequential release would now have mixed data from different overlapping releases. Hi Rex,

As an example of the former, we could tell a tester who was working on a personal finance package to "test check printing." As an example of the latter, we could tell the same tester to: "1. Start the application. You should see the following screen [insert picture of splash screen here]. 2. Use your mouse to select the "check" menu option at the upper left. You should see the following menu [insert picture of check menu here.] 3..." Which of these two approaches--or somewhere in between--is appropriate depends on factors like auditing requirements, skill levels for testers, etc. It's important that the factors influencing test specificity be carefully considered.

I asked the people from the Career Lab about the ways to bring RBCS trainings to Russia. As far as I understand, they are planning the translation of some of your e-learnings. It sounds good!

That book will be out in a few months. We are talking with the good folks at Career Lab about other ways to bring RBCS training to Russia, in Russian. Maybe you and your friends could let them know that there's strong demand for such training? Thanks, Rex Hi Nataly–
