Abstract Wikipedia team/Definition of Done

A Definition of Done (DoD) is a unified understanding of what should be accomplished before a user story, a task or a product release is considered finished.

A Definition of Done can be applied to different development levels, and those depend on the work cycles of every team. This guide is specifically adapted to the workflow and terminology of the Abstract Wikipedia team. We define three main levels of completion: Phase, milestone or epic, and task.

How to use this document
A Definition of Done specification is relevant in two different phases of the development workflow:
 * 1) During phase/epic/task definition: Any item should include a description with the relevant information (list of user stories, detailed user story, detailed bug definition, etc.) and attach an agreed upon checklist with all the criteria that is relevant for this item.
 * 2) During phase/epic/task review and closure: The checklist that was agreed upon phase/epic/task definition should be used to validate the completion of the item.

To write the DoD for a given item, you can follow these steps:
 * 1) Identify the appropriate item level: Are we describing a phase, an epic or milestone of this phase, or a granular task as part of this epic or a bug?
 * 2) Identify the correct channel for writing down the DoD: Should this be written in our project page? Should this be a Phabricator epic or ticket? Will everyone know where to find it?
 * 3) Use the phase/epic/task definition template to write a clear and specific DoD in the right channel.
 * 4) Use the phase/epic/task checklist template to identify which elements should be also considered to validate the completion of the item. Any items that are agreed to be relevant to this phase/epic/task should be copied below the DoD description.

Phase
A development Phase is a collection of user stories (see the Abstract Wikipedia Phase definitions).

Critical User Journey/Epic
A Critical User Journey (CUJ) is described by one Job To Be Done (JTBD) and can involve one or more projects. The JTBD is written from the perspective of the end user/actor/stakeholder, and as such it requires a clear understanding of who this end user is. A JTBD's goal is to clearly understand what the user is trying to achieve, without making strong assumptions about the solution.

The acceptance criteria enriches this narrative by adding functional details to the JTBD, also from the perspective of what the user would expect to accomplish.
