We are looking at implementiong RTC 4... We are currently using Clearcase+Cruise Control+Maven 1. And we will migrate Clearcase to RTC. Some people  will like to go with RTC + Maven + Jenkins + Hudson + Sonar. I was thinking that RTC + Maven only will be enough ? What are the added value, if any, and who could benifit from that compination RTC + Maven + Jenkins + Hudson + Sonar and under witch condition ? We aren't looking for an other IBM product not on Jazz platform, so Build Forge etc isn't what we are looking for.

Thanks
