1. Easy to adopt and use - It is the only tool the whole team could take it further 2. Variable options

The vast feature set across traditional and agile methodologies allows any project management approach. OpenProject is super intuitive to use, there is a great online documentation (and personal support) but it is not really needed. I love that you can do everything in OpenProject and don't need any other tool. Even emails are not necessary because you are communicating in OpenProject, that really helps to streamline communication. We have increased our productivity because all information is in one space and you don't lose time going through different systems looking for the latest information. For me, data security was a big factor as we have a lot of confidential data being processed and OpenProject offers secure hosting (if you use the cloud version, otherwise on-premises is of course even better) and they don't share your data.

OpenProject is open-source and easy to use. It's also easy to customize.
