The feature that we like the most is that JIRA enables modules.
Atlassian provides a lot of products around JIRA, such as compliance for the documentation, BitBucket for the Git version. We are new to these products developed by Atlassian, but they can integrate very easily. Generally, when an editor is developing a solution, they think about integrating with JIRA. When we are looking for any other solution, they plan to easily integrate with JIRA.
The developers can simplify tasks and each one of them can undertake a task and then they continue with development. Our processes are more efficient and easier for our manager and developers to track them. Their work is more organized.
