IBM DevOps Code ClearCase vs. OpenText Dimensions CM vs. OpenText MBPM

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

Serena CM is well suited to highly controlled, audited, and process driven environments. It will allow strict segregation of duties, and change traceability. If implemented correctly it will help you quickly build trusts with your auditors. It is also well suited to environments that require constant branching and merging. Due to the complexity of the product and learning curve for your development and operations team it may be overkill in a small shop with loose rules

Metastorm is well-suited for scenarios in which internal stress testing an application is needed in a hurry before showcasing it to potential customers. It supports different views of the process from Swimlane perspective, so different methodologies can be handled. It is an Enterprise level tool and handles both small and large projects quite well, although smaller companies may be stressed out by the amount of time it takes to properly maintain the application.

• 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.

• Code Promotion: Dimensions CM allows supervisors to control changes to code, in that they delegate requests to developers, and act as a gatekeeper prior to promoting to the next environment. This functionality is configurable so you can set up a workflow that best fits the structure and requirements of your own company.
• Code Repository for changes and versioning: Code can be checked out by item or by synchronizing folders. Code revisions can be compared against other revisions or work files. Item histories show which developers made which modifications, and which supervisor and operations personnel were involved in assigning the request and promoting the code to each environment. Additionally a pedigree will show a stream diagram which graphically displays branches and merges.
• Deployment: Serena Change Management offers help automating deployment including integrations with SVN and Jenkins. Its newer versions also have a powerful graphical deployment automation tool (Serena Deployment Automation- SDA). It comes with a certain amount of licenses built-in. If you have a many nodes to deploy to there will be separate licensing costs for that.

• Complex routing of tasks based on calculated criteria
• Linking between tasks and accessing relevant information
• Organising, scheduling and prioritising
• Different views for different people

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

• The only major negative that I have encountered with Serena CM product is that the very power and flexibility of the tool means there is a risk that you will make a mess of things. In other words it gives you plenty of rope to tangle yourself with. I recommend careful, well thought out deployments implementing the built in roles and workflows that can be turned on and configured, using a consistent methodology.
• My experience with the Serena help desk support has not been impressive. Though reasonably polite and diligent, the technicians were well trained, and often gave bad advise and terrible scripts. On several occasions I had to rewrite scripts they have me; if I had run them as provided they would have caused even more difficulties than the problem I was trying to solve. I speak of the support in the past tense because I conditioned myself not to call them, it was usually just easier to solve nay problems my self. They do have a good account management team though, and for any major issues you can go thru them.

• The Metastorm process engine is based on an older version of .NET. Updating to a newer version would resolve several known issues with .NET email functionality.
• Metastorm builds web pages at run time. While the UI presented to the end user is fine, the Document Object Model is convoluted and subject to change with new releases. Providing a more simplified DOM or at very least a custom function to replace document.getElementById() would make client-side scripting a much more powerful tool.
• One function that I've seen Metastorm competitors do well, is email wizards. Having a WYSIWYG email editor would be really nice.

There are other products that seem to be a better fit for future initiatives.

Although it is intuitive to use it does require training

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.

Serena CM is superior to Microsoft Team Foundation Server (TFS) in overall functionality, but does not have very good native integration with Microsoft. Therefore in a Microsoft centric shop with no audit needs ,TFS would be better. Otherwise I would choose Serena CM

We found that OpenText MBPM held its own quite well against IBM BPM. We ended up choosing OpenText MBPM due to the analytics, complex routing, and the ease of SOA service integration. Furthermore, the ability to quickly develop simple User interfaces make this tool a daily component of our most-used toolbox components.

• 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.

• Serena has facilitated our annual completion of various audit and technology control certifications. These certifications make a huge difference to our company's reputation and bottom line.
• There has been no negative impact on our company.
