IBM Engineering Lifecycle Management (ELM) is an end-to-end engineering solution used to manage system requirements to design, workflow, and test management, extending the functionality of ALM tools for better complex-systems development.
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
The software is robust enough to handle highly complex software development or other product development and can be used well beyond the range to do what a client needs. However, because of the inability to hold its users to proper best practices, things can get wildly out of hand and cascade over the years, creating unnecessary technical debt. The system has a lot of usable features, but they don't funnel users toward the correct processes and practices.
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.
I feel like it is too heavy sometimes and updating is not very straight forward. For example, if I want to change an incident ticket (IN) to a service request (SR) and add some comment for the change, I have to first change the IN to SR, then click refresh which takes a few seconds, then add a comment. If I forget the refresh step, my comment will be discarded without warning like my ticket is not in the latest status. This also happens when somebody else changes the ticket during my edit as I can not lock the ticket exclusively.
At the moment we are required by contract to continue to use the IBM DOORS software for our current client. Given that it can be expensive, if we were to use it after our current client's needs were met, we would have to secure other projects in order to justify the continued use of the software.
The UI is terrible and not intuitive. Users need training in order to complete tasks. Much like SAP, it's not the clearest tool. The tracing feature is especially complicated because you must write the scripts yourself. There is a learning curve. Also, even the setup, installation, and logging in each time takes a considerable amount of time.
It does a basic job and has the potential to complete some robust reporting tasks, however, it really is a clunky piece of software with a terrible user interface that makes using it routinely quite unpleasant. Many of our legacy and maintenance projects still use DOORS but our department and company use many alternatives and are looking for better tools.
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.
It was easier to do all the change management-related activities, even configurations were handled very effectively. New process definitions and initiatives made it easier for better project deliverables. Effective resource allocations and better reporting and defect management. The overall cost of the tool is great too and well within budget.
It's part of CLM suite so it can be used to manage the whole lifecycle with tight integration with development module (Rational Team Concert) and quality module (Rational Quality Manager).
Comprehensive reports and dashboards provide better visibility.
