The INVEST mnemonic was created by Bill Wake^[1] as a reminder of the characteristics of a good quality user story, as may be used in a Scrum or Kanban backlog or XP project.

Letter	Meaning	Description
I	Independent	The user story should be self-contained, in a way that there is no inherent dependency on another user story.
N	Negotiable	User stories, up until they are part of an iteration, can always be changed and rewritten.
V	Valuable	A user story must deliver value to the end user.
E	Estimable	You must always be able to estimate the size of a user story.
S	Small	User stories should not be so big as to become impossible to plan/task/prioritize with a certain level of certainty.
T	Testable	The user story or its related description must provide the necessary information to make test development possible.
