ZenTao is an open source project management system.
The main management theory of ZenTao Project Management Software is based on Scrum, an internationally popular agile management methodology.
In ZenTao, the concepts of product, project and test are clearly defined. Product team, development team and testing team coordinate and check with each other while they are separated. With the interaction through requirements, tasks and bugs between the three teams, qualified products are ultimately made within the project.
