The most valuable features are traceability and reporting. Our organization heavily depends on reports with traceability, starting from requirements to related work items and then to test cases and their statuses. 

We can track the status of test cases (passed or saved) in a single view. Based on releases and other attributes, we generate various reports and extract metrics from the data.

There is a value in certain things like traceability, from high level requirements to low level requirements, to a test case, to a test plan, to a work item, to a change request, which is very essential to have for any OEM trying to not just create data, but also enable tracing. All those things are valuable. It's helpful that the traceability reporting is inbuilt and includes all your requirements, management and test management. There are also  certain integrations with code repositories, to a level where you can trace back and see who actually tested it, whether it was a pass or fail, the length of the test and steps behind it. Anyone coming in will automatically know that something has changed.

I really value the links from stories/defects to code via the tasks and change sets.

Overall, Workflow allows us to manage our stories, sprints, hydration and releases. It's good for that. 

Jazz Source Control allows users to create their isolated sandboxes and deliver code to share streams. Further integration of configuration management with change management activities like stories and tasks is seamless.

• Plan views
• Reporting (JRS)
• A clear picture of engagement
• Resource orientation
• Chartered views

Plans clearly represent the team's availability with load balance, if any. Reporting in certain formats along with live data is certainly helpful to present to higher management without the need to generate them repeatedly.

Backlog management is a valuable feature.

• Task planning
• The possibility to link to DNG
• Easy way to see the status of the project: What was done, why, and when.

All of the features work together to provide a powerful holistic solution - from the dashboard all the way through to security. 

The customization features.

It's easy to plan work.

Agile templates give us a standard methodology for every Agile project. Also, the ability to create our own object types and linkages to features/epics allows us to enhance the verification of feature readiness.

E2E tool for SCM, features like customization of CR and IR flow is valuable.

Change management fully integrates with configuration management. Also, this product can work with almost any software development process you use: agile or traditional.
