7. Augmenting user stories
• In Agile and Scrum big frond-
end design is depreciated
• Time-boxes limit the time to use
in requirements and design
• Forces to go ahead with just
enough information
• Use augmentation only when
necessary
• Keep as light as possible
• User centric design emphasizes
UI designs to help users
understand the requirements
• Storyboards
• Mockups ( PostIt-notes)
• Prototypes
• Other examples:
• Spreadsheet showing business
rules
• Diagram showing a work flow
• Remember: product owner is
available for the Team during
the Sprints !

12. Case: FIFATix
Product
• FIFA has decided to develop dedicated website
(known as FIFATix) for electronic ticket sale and
resale.
Background:
• In some cities, such as Milan, almost all games are
sold out and obtaining tickets through normal
channels is nearly impossible. The resale of tickets at
a profit is illegal and prohibited by the FIFA rules.
Because available auctions like eBay are used to
scalping regardless of the rules, FIFA sees that
scalping can be prevented only by its system
(FIFATix).
Functional requirements
• Register potential sellers of tickets and assign them a
userid and password
• Give staff members of football clubs and other game
organizers including FIFA, UEFA etc. individual
userids
• Register potential buyers of tickets and assign them a
userid and password
• Maintain profiles under the userid, including
organization, email, addresses, preferences, and
credit card information
• Sellers can make tickets available at a fixed price,
which buyers can pay in full via credit card.
• Transferring electronic tickets from sellers to buyers
• Printing electronic tickets
• Checking electronic tickets at stadiums
• Placing tickets up for auction. Telling a floor price,
start of auction time/date, end of auction time/date
and verified ticket information (game days, teams,
number of seats located next to each other and the
seat locations).
• Conducting an auction for the tickets to registered
buyers.
• Successfully concluding the auction by awarding the
tickets to the highest bidder by the end date and, at
the same time, debiting the buyers credit card and
placing the funds in a FIFATix account.
• Notifying the buyer and the seller of the successful
sale of the tickets
• Transferring the funds for the ticket sale less 25% to
the seller
• Transferring the 25% plus any interest to a corporate
FIFA account from the FIFATix account automatically.
• Disqualifying the resold tickets so that only buyers
can have printed tickets that are valid in the stadiums
• Providing information inventory and inventory search
capabilities for teams, stadiums, games, tickets,
dates, and seats.
• Providing for advertising and promotions on FIFATix.
• Ability to identify and ban abusers of FIFATix.
Nonfunctional Requirements:
• 99% availability 24x7.
• Secure for the level of financial activity envisioned
(2,000 tickets per day at an average price of $50).
• 250,000 simultaneous users with sub second
response time.
• Scalable to 1,000,000 simultaneous users as needed.
