I think Jazz is a great technology and Team Concert is a wonderful tool. But the license model kills it. Dead on arrival. Not many companies are buying into it and here is why, and why you should not care either:
Three free user license are a joke. The free edition is useless except for student projects. It's just a marketing gag.
No edition includes free contributor licences needed for people reporting bugs. Say you have 1000 end users, you should buy contributer licences at $630 each. This make RTC useless for product companies.
Floating licenses are another pain point. They are not available for the free or the medium edition. They are only available in the $35k Standard edition.
Usually you get a discount if you buy more licenses. Not at IBM. If you seem to like the product and want more licenses, IBM inflicts massive financial pain on you. First, you can't use the free server for more than 10 developers. It is known to scale nicely beyond 70 users but it is artificially limited to max 10 users. Has IBM ever heard of volume discounts? Hello???
Sure, if you are Fortune 500 company you get 60-70% discounts but if you are not, you won't even get a sales guy talking to you, possibly giving you 5% when you kiss his feet.
If you want say >50 users, you need the 35k server. As if that would not be enough, the price of a developer license jumps from $1260 to $4k on the 35k server. If you go so far, IBM is so nice to offer you floating developer licenses at $7.1k each. A setup with 10 floating licenses is $115k. You still need contributor licenses for bug reporting at $630 or $2k floating.
Stop considering it. Look somewhere else. IBM does not want to sell it. Don't make a fool of yourself suggesting this to your boss.
IBM has a webcast explaining the license model in 10 minutes. 10 minutes!? Why can't the licence model be so simple that it can be explained in 30 seconds, e.g. like for the MS Team Foundation Server? Just take out all these pain points!
IBM also has a ROI calculator online. For my scenario I only got negative ROI. I truly respect that IBM has the guts to list the prices publicly on their website. No need to call an "IBM representative" and getting dragged into professional sales talk. At http://www-01.ibm.com/software/awdtools/rtc/standard/
they list their brain-dead model. Other companies would be ashamed. The arrogance that IBM shows there makes many people hate IBM right away even if they like Jazz and Team Concert.
At that IBM page you can put all those licenses mentioned above in your shopping cart, say the $35k server, 100 developers, 100 contributors, and then pay with your credit card. Or print it for your boss. You get into the range of millions quicly. In a shopping cart! It's pretty funny. IBM has really lost any sense for reality.
Open-source anything? Nothing. You can get the OSLC specifications for free. That's all.
The Rational Requirements Composer is a nice tool as well and has a license model that is broken in a similar way as that of RTC. The licensing starts with three users for $33k. Not even a free edition.
About Erich, I think he is a nice guy and he did a great job. He's the #1 guy suffering from the Incredible Bullshit Machine around him.
