Looking at User Stories through a Distributed Cognition lens



Presenter: Karen Chance. ...

Presenter: Karen Chance.

What is it that makes user stories successful? If a team places the user stories in a list, there is little to distinguish user stories from conventional requirements. However, it is the use of user stories that makes the difference.

This talk explores recent research into one Agile implementation in Auckland. I’ll identify ways by which a software development team “distributes” work through members of the team, artefacts, and the physical environment to ease the task of software development.

Intended Audience: Managers, agile teams, BAs

Level of expertise: Beginner: for organisations kicking off with Agile, or for colleagues newly exposed to Agile but also, for those using user stories at the moment and not getting all they could from them.

    • How software development teams use user stories: adistributed cognition perspective
    • Studying user stories in a real-life context• Mature agile implementation• Interviews to build a user story process• Distributed Cognition for Teams Framework (DiCot)

    • Distributed CognitionMind inescapably part of the worldPeople share and create new thinking with• Other People• Artefacts• Physical Environment

    • What this means for user stories?• Locate what really works and what doesn’t – Turn up what is good – Remove what isn’t• Relate it empirically sound DiCot framework
    • Mediating ArtefactMediating artefacts include any artefacts thatare brought into coordination in the completionof the task (Furniss, 2004).
