Bonita 5.x process that has 6.x version
To learn more about Bonita v6 features, I suggest you watch these videos: http://www.bonitasoft.com/for-you-to-read/videos/whats-great-about-bonit...http://www.bonitasoft.com/resources/webinar/discover-bonita-bpm-6
The 1st one is shorter than the 2nd one, but also more theorical (the 2nd one builds a real process and executes it). They both explain the new features brought by Bonita BPM v6. You should then be able to make your own opinion about it!
I really wish I can do that, but quality metric that I should use require me to measure the quality by using performance monitoring application and calculating the source code design pattern... :'(
I'm so sorry, but thanks :)
