IBM DevOps Code ClearCase vs. IBM Rational ClearQuest

Rational ClearCase is well suited for a company where development is done from one single location and there are a lot of dependent projects, systems or modules that need to be version controlled. Especially good for a company that creates customized software for clients. Well suited for disciplined development environments. Waterfall methodology mentality seems a better fit for ClearCase than Agile.

ClearCase is not well suited for companies that have development geographically distributed and using Agile Methodologies.

Well Suited - If your project is running in waterfall model and other IBM tools are widely used for various purposes, Clear Quest is a good tool to have. It gives you seamless capability to create defeccts and query the defects for various scenarios. If you are a project manager or a test engineer trying to create defect metrics, this tool can help immensely. Less Appropriate - In this Agile world, everyone uses Jira or some other agile tracking tool. All the agile tracking tools have already built in defect tracking capabilities and can integrate with the work very well. If your project is running on agile or don't use IBM tools that much, then Clear Quest doesn't always add value.

• 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.

• IBM Rational ClearQuest records and workflow are highly customizable. As a result, ClearQuest implementations can be tailored to any organization's methodologies.
• IBM Rational ClearQuest Integration with IBM Rational ClearCase provides traceability between work records and source code changes, expanding the SDLC scope of the toolset.

• Extremely buggy.
• Sometimes the repository gets locked for no reason.
• Slow.

Incentivized

• Lot of defect management tools are out there and are free to use
• In agile world, teams use Jira or other tools and they have the defect tracking capability builtin
• Don't really see the need to use this tool in agile world

Most likely as it's one of the powerful tools in the organization. We needed this tool to track all the process related documentation and also to capture signatures.

Please keep in mind that this all has to do with you you customize the user interface. It becomes very easy to house all of your requirements, but it may and can make life difficult for you if you do not think ahead of how you want the app to work and house your data

IBM has good support and knowledge base. With the wealth of information on their site and the support desk, we were able to quickly resolve issues. It is smart to build up a COE and a group that manages the software otherwise it is quick to be able to lose the knowledge as team members are assigned different duties

It was pretty simple.

GIT Stash is superior to IBM Rational ClearCase in many ways. Bundled with SourceTree, the UI is far more modernized and updated than IBM Rational ClearCase. Being able to visually see the individual branches that are created within the repository is much more straightforward than the versioning method of ClearCase. GIT also seems to be a lot faster when it comes to checking in/out code and creating the repository.

IBM Doors could be better at document management for a higher price. If you need more complex traceabilily, Doors is the way to go. If you need less, free and simple management, a common SVN is ok for you.

• Managed code versioning for many years.
• Only one person can edit code at a time - slows processing down.
• IBM is an expensive product to support.

Incentivized

• Positive: Quality product that adheres industry best practices for a considerably cheaper cost.
• Negative: Maintenance of more than one tool for overall project management.
