It helps us deliver working software in a fixed time period with continuous delivery and over time helps us understand the work capacity of the team.
We define done as something that is completed with its agreed requirements.
An Epic is a requirement that is just too big to be delivered in a single sprint. It needs to be broken into smaller deliverables (vertical slices) stories.
Example:
As a customer, I want to be able to have a wishlist so that I can come back to buy products later
Deliverable stories that we can extract from it:
- As a customer I want to save items in my wishlist so I can review/manage them later
- As a customer I want to view my wishlist so I can buy products from there
User stories are short, simple descriptions of a feature told from the perspective of the person who desires the new capability, usually a user or customer of the system. They typically follow a simple template:
As a [type of user], I want [some goal] so that [some reason].
It is a thin and deliverable vertical slice.
Usually a story is composed by 1 or more tasks and 1 or more people can work on it.
- When there is no more outstanding tasks; And
- When a [type of user] can now [achieve a goal] so that [the reason is now covered]
A task is a small piece of work that will at some point help completing the story that owns it.
It is typically something like code this, design that, create test data for such-and-such, automate that, and so on. These tend to be things done by one person.
- When it doesn't require any extra work to accomplish its objective.
We simply add the task to the story and continue working on it.
We simply create a new story. It could be "Improvement of feature X". If the previous story was finished, it certainly had achieved its first goal.
