Track-It! is great for a small-to-medium sized enterprise that has a fairly small IT department but needs far more control of tickets than just email and spreadsheets. It scales well enough as IT departments grow, adding techs is simple enough, as is changing the workflow. A large company would probably be better off with a different solution. The lack of easy customization, and the shortcomings it has in workflow templates (which would be a nightmare for project management) means it won't scale up that far.
IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control
Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
Rational ClearCase handles parallel development of many dependent applications really well.
The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.
We have rarely needed to use Support for BMC Track-It!, but in the times that we did need to use it, they were excellent. The biggest issue is that after not paying for support for about three years, now that we NEED support, it is too expensive for us to receive. This is due to the way their support is billed. So long as you never drop support, then you should be fine.
BMC Track-It! is much more bare bones compared to ServiceNow products, and if your department has the money, ServiceNow is a much better option. Not only is the Knowledge Base much easier to create and publish articles, but the asset management in BMC Track-It! is practically useless. BMC Track-It! is more cost effective, and with a small amount of technicians there's likely no reason to need a bigger solution, but it leaves a lot wanting.
If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.
The biggest positive impact it had on ROI was that the software itself didn't require any expensive ongoing maintenance contracts since it was installed and managed by our organization.
The negative aspect of this is if there was a major problem with the software, then it would require contacting the vendor, at which point it could become expensive for a service call.
