The Importance of Small User Stories in Agile
Small user stories are essential for Agile success because they facilitate better planning and execution. By keeping stories small, teams reduce the likelihood of carrying work over from one sprint to another, a common issue in many organizations due to poor planning and forecasting. Smaller stories are easier to estimate and manage, helping teams to maintain focus and efficiency. While not every story can or should be small, especially for longer-term planning, the overall strategy should prioritize the reduction of story size for immediate tasks.
N Plus Two Planning Methodology
The N plus two planning methodology provides a framework for managing user stories effectively as projects evolve. This approach encourages teams to refine their stories and break them down into more manageable pieces as they move closer to implementation, ensuring adequate detail and planning for upcoming sprints. By adopting this method, organizations can maintain a clear backlog and adjust their planning for potential changes more efficiently. This allows product owners to focus solely on creating and refining backlog items, reducing the risk of overwhelming them with extraneous responsibilities.

The Importance of User Story Size in Agile Planning
Small user stories are essential to success with agile. When it’s time to bring stories into an iteration, I always want them to be small. But larger stories have their place as well–especially for something you're not going to work on imminently. Suppose you have just begun work on a new product that will include a set of reports. Because this is a new product, there is nothing to be gained by writing a bunch of small user stories around each one of those reports at this point, especially since you don't yet even know all of the reports that will be needed. At this stage of the project, having one big reporting story rather than a bunch of little ones keeps the size of the backlog more manageable. You'll have one entry in your tool instead of 15 or 20. That's much easier to manage. Further, if you do write all the small user stories, one per report, it gives the impression that you've thought of everything. Early in a project, that's probably not true. New reports will be identified and some that are asked for initially may not be necessary. Don’t fall into the trap of thinking every story needs to be small from the beginning. They don’t. Instead, plan for stories to shrink in size and grow in detail as they move closer to being brought into a sprint. For most teams, this will happen during the product backlog refinement meeting one or two sprints before the iteration planning where they’ll be considered. Letting timing dictate story size will help you succeed with user stories and with agile.
