Scenario 1
Background
Southbridge Video rents and sells video games, movies, and other multimedia content. The
company is currently expanding its operations. Southbridge video is developing a Windows
Store news reader and social media app. Users will be able to view and interact with news
stories that are related to the video game, entertainment, and related industries. Southbridge
Video employees will also use the app to manage sales leads, order fulfillment, and customerservice related activities.
Business Requirements
The app has the following requirements.
Email
Users must be able to email news items to their contacts.
Navigation
• Easy navigation access must be available to move to the next and previous pages.
• Users searching for specific news items must be able to navigate directly to an item
from the search results pane.
News items
• When a user selects a news item on newsPage.html, the news item should be
displayed in the newsltem.html page.
• The app must periodically retrieve new news items on the newsPage.html page.
• The app must allow the user to save annotated news.
• The app must display a short title for each news item.
Search capabilities

interest.
• The app must provide search suggestions for users.
Authentication
• Employees must be able to view the sales leads, order fulfillment, and customerservice related pages.
• Authenticated users must be able to save news items to read at a later time.
• Authenticated users must be able to add and save handwritten notes to the news items.
• The app must allow users to choose whether their credentials will be saved after they
first log in. User credentials must be saved by default.
Technical Requirements
Email
• When a user clicks the To button to email news items, only contacts that have email
addresses should be displayed.
• When multiple contacts are selected, the email addresses must be displayed in the To
text box as a semi-colon-delimited string.
News items
The app must periodically retrieve new items from a web service. The app must display a
progress indicator while retrieving new items.
The news feed service must respond to all requests within 15 seconds. The app must not
throw an error if the service does not respond within the allotted time.
Titles for news items must not overflow into other elements on the page.
Authenticated users must be able to add handwritten notes to the news items by using a stylus
or the mouse. The app must support saving annotations along with the news item. The app
must cancel the navigation from newsltem.html to newsPage.html if there are unsaved
changes in the annotations area.
Search capabilities
The app must retrieve a list of phrases from the news service and provide them as search
suggestions to users.
Authentication
• Users connected to the corporate network must authenticate against an Active
Directory server.
• Users outside of the corporate network must authenticate by using forms-based
authentication.
• User credentials must not be transmitted in plain text.
Application Structure
Relevant portions of the app files are shown below. (Line numbers in the code segments are
included for reference only and include a two-character prefix that denotes the specific file to
which they belong.)
