It is easy to use, customizable, quick reporting system with ability to attach documents. There are some features that I don't like as much such as being able to create custom report types (in terms of fields available) but this could be improved upon by adding more flexibility. It's not difficult to learn how it works or customize it for your needs if you have basic knowledge about creating reports in any other software. This has helped us structure our annual planning processes and improve our overall performance management systems. The simplicity of setting up okr-sprints using an excel sheet is just amazing, you can easily track your progress for any sprint in few minutes without having to install some software or anything like that! I wish there was more customization options such as adding templates (elements) etc., but overall it's great product with simple UI & easy tracking features which suits perfectly my needs at this point.
