Why we use stories
• Stories are the smallest unit of work
that provides business value
– Sized by effort to ensure completion in a twoweek iteration
– Prioritized by value to ensure successful delivery
• Stories are written in the language of
business and describe:
– Preconditions
– user actions
– system results
• Stories describe ‘what’ not ‘how’
– Solutions are created by the whole team
– Alternatives are often better than the original
conception

Backlog Creation
& Management
• Story format:
As a <role>
I can <action>
So that <value>
• Feature/Epic/Story decomposition provides a
foundation for elaboration at the right time
• Relevance to scope and business value can
be checked throughout the process
• Ready backlog for about two iterations
creates enough cushion to handle changes
• A regular cadence for prioritization
& estimation occurs within each iteration
• Grooming the backlog happens every day –
adds & deletes welcome

Collaboration
• Cross-discipline discussion is the norm stories cannot be considered ready for
development without conversation
• Business sign off happens before testing and
development can begin
• A common understanding of scope ensures
value delivery for the business & the user
• Ambiguity is removed through conversation
not narrative - more words does not equal
better understanding
• Trust your team mates and put your ego
aside
• Be here now!

Clear Definition of Done
• Keep it simple – the human brain can only
remember 5 to 7 things at one time
• Non-functional requirements need to be
measurable so they can be verified and
validated
• User focused requirements keep attention on
those who will interact with the system
• Acceptance criteria in Gherkin or
Given When Then format is an easy-to-use
adaptation for communication of DONE
• Stories are written in partnership with testing
& development - varied perspectives create a
holistic picture
• The depth of elaboration depends on the
needs of the team
