+For a Technology Team Manager, the process improvement in search of agility and productivity is indispensable. For that, data is very important.
+
+
+However, for teams that use [Azure DevOps](https://dev.azure.com/) for managing their tasks, there isn't in-depth documentation about what happens to Work Items, and the available Azure DevOps Queries are limited.
+
+With **Azure DevOps Tracker**, it will be possible to obtain detailed information about the cycle time of each Work Item, as all data is automatically stored in your SQL Server Database.
+
+
+The **Azure DevOps Tracker** brings automatically tracking of Workitems and will help managers with:
+### Statistics:
+✅ Of the Team
+
+ ✅ From specific Team Members
+
+ ✅ Total time per State
+
+ ✅ Worked time per State
+
+ ### Cycle time sampling of:
+
+  ✅ An iteration or Sprint
+
+  ✅ A Workitem
+
+  ✅ A Project
+
+### Changelog: With Azure DevOps Tracker you can easily inform what was done by your team. Actually, we have integration with Microsoft Teams and Discord!
+
+ ### Possibility to connect to a BI Tool 📊
+ ### Your creativity is the limit! 🚀
