We start discussing user requirements and two of the most representative ways are use cases and user stories. We will discuss both of them: what they are about, differences between them and how the modelling process goes on after their definition. We also look into how to write effective user stories for their management and implementation, looking at some suggestions.

Lecture

• User Requirements: Use Cases vs User Stories
• Agile Requirements: Elicitation & User Stories
• Additional slides about  wicked problems in requirements engineering and the goal-design scale [not at the exam]
• Example for the user story structure
• Suggestions on how to split user stories (part 1, part 2), from Leffingwell's book

Additional Material

The following is a sample from the book G. Adzic and D. Evans, Fifty Quick Ideas to Improve your User Stories. Leanpub, 2013, that takes a practice-oriented approach in giving suggestions about the improvement of the creation of User Stories (http://leanpub.com/50quickideas).

Tools for User Stories / Use Cases Support

The following tools can be useful to create user stories and use cases:

User Stories:

• Trello (probably fastest tool to start using to write user stories)

• Any UML tool supporting Use Cases
  • ArgoUML (probably fastest to start using, there is also a webstart application)
  • Visual Paradigm (more complete but you will need a license after the trial and takes more time to learn)
