User Stories Applied For Agile Software Develop...
The best way to build software that meets users' needs is tobegin with "user stories": simple, clear, brief descriptions offunctionality that will be valuable to real users. In UserStories Applied, Mike Cohn provides you with a front-to-backblueprint for writing these user stories and weaving them into yourdevelopment lifecycle.

After teaching User Stories to more than 20,000 people I know they help teams deliver high-quality products to market faster. But I also know there are still too many agile teams struggling to master them. If you're finding user stories difficult to work with, you'll love this free training.
In software development and product management, a user story is an informal, natural language description of features of a software system. They are written from the perspective of an end user or user of a system, and may be recorded on index cards, Post-it notes, or digitally in project management software.[1] Depending on the project, user stories may be written by different stakeholders like client, user, manager, or development team.
User stories are written by or for users or customers to influence the functionality of the system being developed. In some teams, the product manager (or product owner in Scrum), is primarily responsible for formulating user stories and organizing them into a product backlog. In other teams, anyone can write a user story. User stories can be developed through discussion with stakeholders, based on personas or are simply made up.
A template that's commonly used to improve security is called the "Evil User Story" or "Abuse User Story" and is used as a way to think like a hacker in order to consider scenarios that might occur in a cyber-attack. These stories are written from the perspective of an attacker attempting to compromise or damage the application, rather the typical personae found in a user story:[17]
A central part of many agile development methodologies, such as in extreme programming's planning game, user stories describe what may be built in the software project. User stories are prioritized by thecustomer (or the product owner in Scrum) to indicate which are most important for the system and will be brokendown into tasks and estimated by the developers. One way of estimating is via a Fibonacci scale.
When user stories are about to be implemented, the developers should havethe possibility to talk to the customer about it. The short stories may bedifficult to interpret, may require some background knowledge or therequirements may have changed since the story was written.
The appropriate amount of information to be included in the acceptance criteria varies by team, program and project. Some may include 'predecessor criteria', "The user has already logged in and has already edited his information once".[This quote needs a citation] Some may write the acceptance criteria in typical agile format, Given-When-Then. Others may simply use bullet points taken from original requirements gathered from customers or stakeholders.[citation needed]
There is no good evidence that using user stories increases software success or developer productivity. However, user stories facilitate sensemaking without undue problem structuring, which is linked to success.[21]
In many contexts, user stories are used and also summarized in groups for ontological, semantic and organizational reasons. Initiative is also referred to as Program in certain scaled agile frameworks. The different usages depend on the point-of-view, e.g. either looking from a user perspective as product owner in relation to features or a company perspective in relation to task organization.
While some suggest to use 'epic' and 'theme' as labels for any thinkable kind of grouping of user stories, organization management tends to use it for strong structuring and uniting work loads. For instance, Jira seems to use a hierarchically organized to-do-list, in which they named the first level of to-do-tasks 'user-story', the second level 'epics' ( grouping of user stories ) and the third level 'initiatives' ( grouping of epics ). However, initiatives are not always present in product management development and just add another level of granularity. In Jira, 'themes' exist ( for tracking purposes ) that allow to cross-relate and group items of different parts of the fixed hierarchy.[23][24]
In this usage, Jira shifts the meaning of themes in an organization perspective: e.g how much time did we spent on developing theme "xyz". But another definition of themes is: a set of stories, epics, features etc for a user that forms a common semantic unit or goal. There is probably not a common definition because different approaches exist for different styles of product design and development. In this sense, some also suggest to not use any kind of hard groups and hierarchies.[25][26][27][28][29][30]
A story map[32] organises user stories according to a narrative flow that presents the big picture of the product. The technique was developed by Jeff Patton from 2005 to 2014 to address the risk of projects flooded with very detailed user stories that distract from realizing the product's main objectives.[citation needed]
The horizontal cross-cutting narrative line is then drawn by identifying the main tasks of the individual user involved in these business activities. The line is kept throughout the project. More detailed user stories are gathered and collected as usual with the user story practice. But each new user story is either inserted into the narrative flow or related vertically to a main tasks.
This allows to map the user experience beyond a set of user stories. Based on user feedback, the positive and negative emotions can be identified across the journey. Points of friction or unfulfilled needs can be identified on the map. This technique is used to improve the design of a product,[38] allowing to engage users in participatory approaches.[39]
A use case has been described as "a generalized description of a set of interactions between the system and one or more actors, where an actor is either a user or another system."[40] While user stories and use cases have some similarities, there are several differences between them.
A large user story that awaits decomposition into smaller stories prior to implementation. When an epic story works its way up the backlog, it is usually so decomposed. Epics are sometimes far off on the development horizon and have lower priority.
In software development and product management, a user story is an informal, natural language description of one or more features of a software system. A user story is a tool used in Agile software development to capture a description of a software feature from an end-user perspective. A user story describes the type of user, what they want and why. A user story helps to create a simplified description of a requirement.
User stories are often recorded on index cards, on Post-it notes, or in project management software. Depending on the project, user stories may be written by various stakeholders such as clients, users, managers or development team members.
"User stories are part of an agile approach that helps shift the focus from writing about requirements to talking about them. All agile user stories include a written sentence or two and, more importantly, a series of conversations about the desired functionality" - Mike Cohn, a main contributor to the invention of Scrum software development methodology

With user story approach, we replace big upfront design with a "just enough" approach. User stories reduce the time spent on writing exhaustive documentation by emphasizing customer-centric conversations. Consequently, user stories allow teams to deliver quality software more quickly, which is what customers prefer. There are quite a few benefits for adopting user story approach in agile development such as:
A user story is a lightweight method for quickly capturing the "who", "what" and "why" of a product requirement. In simple terms, user stories are stated ideas of requirements that express what users need. User stories are brief, with each element often containing fewer than 10 or 15 words each. User stories are "to-do" lists that help you determine the steps along the project's path. They help ensure that your process, as well as the resulting product, will meet your requirements.
Ron Jeffries, another of the creators of XP, described what has become our favorite way to think about user stories. A User Story has three primary components, each of which begin with the letter 'C': Card, Conversation, and Confirmation to describe the three elements of a user story. Where:
You don't have to have all of the Product Backlog Items written out perfectly "up front", before you bring them to the team. It acknowledges that the customer and the team will be discovering the underlying business/system needed as they are working on it. This discovery occurs through conversation and collaboration around user stories. The Card is usually follows the format similar to the one below: 041b061a72
