Just to add my 2 cents worth to the clear case discussion...
We have just migrated away from clearcase / clearquest _to_ TFS ( mainly due to our dissatisfaction with clearcase in particular) - Our experience was that CC was exceptionally slow - and basically unusable over VPN type connections - due to the heavy network usage (we suspected). Not having used source proxies in TFS (I believe this is a way of speeding up source control delivery over WAN type environments) - I believe that the equivalent in clearcase is using multi site to replicate source control repositories between multiple sites. Couple of points from my experience: * The way we had our projects set up was using UCM - meaning that all work on source control had to be associated with defects - the same as we are working for TFS * Work items cannot be transferred from one project to another - so if a work item is incorrectly created in a projects - it has to be replicated in the correct project. * CQ appeared to be more workflow configurable (ie: controlling what users can move defects between states) * I didn't feel that CC/CQ gave a level of abstraction between source and projects - it was (as we were using it ) strongly project based. * For us, the productivity gains over using TFS has far outweighed the few shortcomings functionality wise over CC/CQ - and then again they are probably there because we are not fully aware of the full capabilities of TFS :-) Hope this helps, Rohan ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Butcher, Justin Sent: 09 May 2007 01:41 To: [email protected] Cc: Brad Smith (AUSTRALIA) Subject: [OzTFS] Thoughts on Clear Case / TFS integration [SEC=UNOFFICIAL] HI All, I work for a large (by Australian Standards) government organisation (the ATO) that does a lot of software development across a range of platforms. We are increasing the scope of TFS usage to about 500 users in the very near future (currently about 200). We are currently evaluating the Clear Case and Clear Quest Product Suite with a view to understanding how it might either complement or replace TFS. We are currently using TFS to manage a number of projects including a fairly large project in which TFS manages several 100,000 lines of both Cobol and .Net code. The integration with the Cobol editor is quite reasonable, using the MS SCCI provider. We also have pockets of Eclipse (Java, MQ Series) and other platforms which are (or very soon will be) using TFS. I've noticed the following which seem to be limitations of either product and I was wondering if people could comment of the following points: 1. TFS tightly couples source code to work-items, reports and team collaboration. As a large enterprise with lots of teams and lots of projects over time, my team (enterprise architecture) wants to ensure that we have a view of the source code that is based on the software assets. We don't want the primary view of the code to be based on projects, which are centred around tasks, timelines and people. We want a view that shows how the source fits into the over-arching enterprise architecture framework. Because TFS uses the Team Project as the top-level organisational unit, source gets organisated around projects, rather than being organised as the resulting assets that projects deliver. It seems like Clear Case / Clear Quest supports this concept better, with a better layer of abstraction between source organisation and projects / workflow. But I've not used Clear Case. Am I right? 2. Does Clear Case support the idea of source proxies like TFS? 3. I know that TFS supports migration from Clear Case specifically and integration with Clear Case. Has anyone got real experience with this that they can share? Thanks, Justin. **************************************************************** IMPORTANT The information transmitted is for the use of the intended recipient only and may contain confidential and/or legally privileged material.
