It's very useful for my Scrum team. I can't imagine that ZenTao is been more than 10 years but I just noticed this excellent tool. It deserves to have a try!
It is very flexible and fitted really well with agile development work. whether you are using kanban ,waterfall and scrum work flow, it supports all of those.
A very nice and cheap scrum tool to do practice in our Dev&QA team. It's very good at application lifecycle management as well. The modules like bugs, tasks, and story details are complete. Thank you ZENTAO team.
