How Stories Define System Behaviour In Agile?

 

In Agile software development, stories are a main artifact used to define the behaviour of an Agile system. These are short, simple functional descriptions written in a language that users can understand. Each story is a bite-sized chunk of work that can be done to enable the vertical expansion of portions of the system.

As stories are finished, more and more functionality is developed within the system. Functionality is delivered incrementally and often includes story points that represent business value. Details are put off until the story is ready to play. Acceptance criteria and testing make the stories more detailed and help ensure the quality of the system.

The SAFe certification is one of the most popular certifications in the industry. SAFe training teaches you how to apply agile methods like Lean Startup, Design Thinking, or Agile Product Management.

What Are Stories?

The SAFe Requirements Model describes a hierarchy of four levels of artifacts that describe the functional behaviour of the system: Epic, Capability, Story, and Feature. Together, they describe all the work to create the intended solution behaviour. However, the detailed implementation work is described in the stories that make up the team lag. Most of the stories come from a backlog in the business and enabler features from the program backlog, but others come from a local team context.

Stories are short summaries of a small feature written in the user's language. Agile teams develop small vertical segments of system functionality and implement them in a single iteration.

Types Of Stories

Use Stories

User stories are the most important tool for expressing the functionality required. They fundamentally change the traditional specification of requirements. However, in some cases, they are used to explain and develop system behaviour, which is then incorporated into specifications for compliance, supplier, traceability, or other requirements.

Enabler Stories

The teams are also developing the new architecture and infrastructure needed to implement new user stories. In that case, the story should not directly affect any end user. Teams use stories to support exploration, architecture, or infrastructure. Activating stories can be expressed in technical language, not user oriented.

What Is Required To Write Good Stories?

Agile, the entire team - developer, product owner, and tester - builds a common understanding of what needs to be developed to reduce redesign and increase throughput. Teams work with BDD (Behaviour Driven Development) to identify end-to-end acceptance testing that accurately describes each story. Good stories require several perspectives:

 

1.      Product owners provide the customer with thinking about the importance and the desired options.

2.      Developers ensure technical feasibility.

3.      Testers provide a high-level view of exceptions, extreme cases, and other unexpected ways users interact with the system.

What Are 3C’s Of Stories?

Card

Gets the statements of user story’s intentions with an index card, sticky note, or source. The cards create a physical link between the story and the team.

Conversation

It is necessary to find out more about the card. The conversation encourages the gradual and continuous collaboration of the agile team needed to develop a common understanding of the problem and a possible solution.

Confirmation
It is an acceptance criterion that includes the basic needs and transforms them into test criteria so that we understand when we successfully submit a user story.

Scaled Agile Framework (SAFe) is the most widely adopted agile in the enterprise, where it addresses enterprise-scale challenges such as large-scale product development, organizing complex development efforts with multiple teams and dependencies, and bringing together functional and cross-functional teams.
