Each story could be have an estimation of 1, 2 or 3 weeks, in &#8220;ideal development time&#8221;. This ideal development time is the length of the time working with no distractions or other assignements.<\/li>\n<li>The user story estimated to more than 3 weeks &#8211; they are called\u00a0<strong>epics<\/strong> &#8211; \u00a0need to be broken down further. Those estimated to less than 1 week could be combined because they are at a too detailed level.<\/li>\n<li>They are prioritised\u00a0&#8211; the customer priorities the user story with a\u00a0High\/Medium\/Low criteria or 1-10 numbers. This prioritisation could be changed at some point, depending on the customer needs. Epics have lower priority because they include more smaller user stories.<\/li>\n<li>They focus on their needs and benefits not on specific GUI layout, algorithm, technology, database, etc.<\/li>\n<li>They provide enough details to make a reasonably low risk estimate of how long the story will take to implement. Detailed description of the requirement will be asked to the customer when the developers need to.<\/li>\n<li>They drive creation of acceptance tests<\/li>\n<\/ul>\n<p>Well-written user stories follow a set of criteria called <strong>INVEST<\/strong>:<\/p>\n<ul>\n<li>We can be able to move stories around.

They are <strong>Negociable<\/strong> (<strong>N<\/strong>).<\/li>\n<li>In order to deliver continually valuable software, stories focus on the end-user (stakeholders), bringing them value. They are <strong>Valuable<\/strong> (<strong>V<\/strong>).<\/li>\n<li>Part of an iteration, the user story must have a size for the working effort. User stories are\u00a0<strong>Estimable<\/strong> (<strong>E<\/strong>).<\/li>\n<li>User stories have to be small enough to be implemented within a sprint (2-4 weeks). Thus, they are <strong>Size appropriately<\/strong> or <strong>Small <\/strong>(<strong>S<\/strong>).<\/li>\n<li>As long as the user stories are DONE (tested), it means that the acceptance criteria were passed.
