3–5–3 Structure in ZenTao
Based on the philosophy of Scrum, ZenTao integrates bug management, test case management, CI, and document management, and it completely covers the entire life cycle of software development. In ZenTao, the concepts of product, project, and test are clearly defined. The product team, developing team, and testing team coordinates and check with each other while they function differently. The three teams interact with each other through stories, tasks, and bugs, and eventually deliver the product with quality.
