Links Hierarchy helps organizations to embrace Atlassian's vision of Agile instead of replacing it with a vendor's proprietary solution.

Does not store any proprietary. Therefore your Jira instance will not be tied to a specific vendor.

You are free to use Links Hierarchy together with any other app compatible with the standards of Jira.

Does not require any configuration. Brings a lot of peace of mind to the Jira administrators as . It requires 1-click only to be installed on Jira fully working out-of-the-box and giving value from the first instant to every user. 

Links Hierarchy is agnostic in regard to the methodology. So it can be used in a wide range of scenarios and by a lot of different user skills. It supports Agile structures (Epics, Portfolio, Sprints,..) of issues related to regular Jira links  (.ie: "is blocked by") but also can be used to track progress and dependencies of issues and complex JQL queries. 

Provides a full unified context with the key information available at a glance while users are effortlessly involved. The collaboration is improved in a natural way with a friendly UI and outstanding graphics.

Some Links Hierarchy features are unique in the Marketplace. I.e: while the progress of Epics and issues is immutable in the rest of the apps at a given instant, the progress becomes dynamic in Links Hierarchy: users can apply filters on issues contributing to the progress on every hierarchy and get a customized view tailored to their needs.

Hierarchies and JQLs can also be loaded onto a Pivot Table for further analytics and reporting providing traceability at scale.

Excel integration is superb and allows exporting data by preserving the view layout (hierarchy, pivot table, matrix).
