filled up with things I don't need saved.

User story
mapping
• Agile approach to refine
difficult tasks.
• From user perspective.
• Helps us focus the
conversation.
• Helps us define priorities.
• To keep in mind:
• Deliver sooner, not faster.
• Only one conversation.
• Don’t move forward until all
important information are
noted.

Splitting user stories
As a user, I want to see national holidays in calendar, so that I know when I don’t need to go to school.
Dev team: Which national holidays? Only Czech or Slovak?
PO: According to institution location – if the faculty/university is in Czech, then Czech holidays, if it
is in France, then France holidays etc.
Dev team: It’s too complicated. Would it be ok to split it to two stories:
“Show only Czech holidays” and “Show holidays according to location”?
PO: Sure. But I want to release is ASAP and I don’t want French students to see Czech holidays.
Dev team: No problem. We will put there feature toggle so that first story will be only available for Czech.
PO: Deal.
A good user story
• “I” ndependent (of all others)
• “N” egotiable (not a specific contract for features)
• “V” aluable (or vertical)
• “E” stimable (to a good approximation)
• “S” mall (so as to fit within an iteration)
• “T” estable (in principle, even if there isn’t a test for it yet)
