I'm a product owner without any technical background especially without a correct sense from the back-end development process and tasks. I have a brief knowledge about MVC architecture but our team uses customized architecture so I'm almost blind to the technical concept of back-end part of our project.
The problem appears when I want to breakdown user stories into tasks with the back-end team. I cannot understand anything about their tasks and I just jot down their orders and then import them to the JIRA.
When a task was done, I can't realize what part of the project has been progressed, because usually the tasks are related to many user stories. In fact, the back-end team told me!
I have this problem with neither the mobile team nor the front-end, because their tasks have a pattern so I can predict the other user stories' tasks based on it and understand them.
So is there any template or pattern for Back-end tasks or any related hint?
