Another option... Agile User Story Splitting – Vague Words + MVP to Enhanced, Agile User Story Splitting – Low then High Fidelity + Build vs Buy, Agile User Story Splitting – Error Handling & Logic + Interface Variations, Agile User Story Splitting – Split Conditions + Major Effort, Agile User Story Splitting – Manual vs Automated + Zero-One-Many, Haven’t been discussed, questioned, or negotiated (or you skipped the conversation), Have no value to the customer or end users, Don’t have enough information to be sized or estimated by the team, Written from a Product Owner’s perspective (WRONG), Written from a Developer’s perspective (WRONG), Written from a generic user’s perspective, without considering other roles, Stories are split horizontally (by technical layer) instead of vertically, They are sliced in ways that don’t deliver value, Don’t include the “why” part of the story – they just state what the user wants, Don’t include conditions of satisfaction (boundaries for testing), Include the look and feel (they shouldn’t), Don’t include enough information to be truly “suitable for development”, Have no definition of “Ready” for stories, Don’t include items such as non-functional requirements – which are often overlooked (or could be included in the team’s definition of done, since they often apply broadly across a project).

We decided to see if there were any other ways to keep our stories independent and score them accurately. It’s an end goal, not a feature, expressed from the software user’s perspective. In more complex cases, where you need to develop complicated functionality that's to big for a single story, we've found that we can still divide things up in to smaller stories and that doing so yields a more successful project overall.  In most cases, you still can't release the functionality to an end user, but allowing the PO to see things as they progress means that you get feedback on the development of complex functionality without having to complete the whole thing and potentially wasting time working on something that isn't in line with the PO's expectations or needs.  In addition, by writing independent stories, we can stop working on the functionality if an urgent business need comes up without having to leave a story partially done and forget where we were when we come back to it weeks or months later.

TestableThe common User Stories template includes the user, the action and the value (or the benefit) and typically looks like this: Or, put another way… I got (sic) some tasks that I consider story-independent, for example, configuring some stuff in the production environment for a web app. 15.3 User Stories 15.3.1 What is a User Story?

The story card was left with a blank area for which report would be the first one, which our product owner would fill in when she selected that story. The “map” arranges user activities along the horizontal axis in rough order of priority (or “the order in which you would describe activities to explain the behavior of the system”).

On the surface, this seemed easy; as we dug into the acronym and started applying each bit, however, we discovered that it was much more difficult than it sounds. However, the remaining stories were then taking much less effort to complete than we had initially estimated, because the first story laid the groundwork for the rest of them.

While in theory we thought this would work well, in practice we found that our product owner rarely wanted to implement the functionality on all the remaining reports at the same time. They are the primary input to the scrum team. We typically spend a little more time discussing these stories during grooming so that we have a better idea of what it will take to complete them. Each story is a small, independent behavior that can be implemented incrementally and provides some value to the user or the Solution.

All we had to do was "INVEST" and make our stories: IndependentNegotiableValuableEstimableSmallTestable.

This way our product owner has the ability to select whatever story she wants based on where she feels she will see the most business value, and we do not have to re-evaluate our scores after the first story is played.

In Agile a user story is a short, informal, plain language description of what a user wants to do within a software product to gain something they find valuable.
