User Stories
By successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and assignment criteria:
- Competency 1: Define business problems that can be solved using software architecture concepts and standards.
- Competency 2: Explain fundamental concepts and principles of software architecture.
- Competency 3: Create a software and data architecture for an organization.
- Competency 5: Communicate effectively.
Assignment Overview
The Scrum process is one of the more successful software-architecture processes used today. For this assignment, you will apply one part of the Scrum process to the Fantasy Games scenario—the creation of user stories. The user stories become the product backlog of the Scrum process. In order to complete this, first review the Fantasy Games scenario.
Fantasy Games Scenario
Your consulting company has been hired by the CIO to design the software architecture for Fantasy Games. The company is adding a new game titled Asteroids to its catalog and intends to build a multiplayer environment for this new game. In order to support this game, an entirely new subcomponent needs to be added to their existing Web community. You are to create a software architecture proposal for this new subsystem. As part of your proposal, you have been asked to develop a single-player working prototype of the game itself.
The Fantasy Games community currently has 1.2 million users, and they expect that user activity will grow tremendously with the addition of this new environment. Your design must be flexible enough to accommodate the current number of users and all anticipated and unanticipated future growth. The Asteroids Web component, or subsystem, for this game should include many of the same features found on other popular online-gaming sites such as chat, instant messaging, user-rank functionality, and high-score display. Although Fantasy Games currently has a few other multiplayer games available within their overall community, they would like this project to set the new standards for how similar subsystems will be added in the future.
Assignment Preparation
For this assignment, you will apply the Scrum process to create user stories for the Fantasy Games scenario. You need to create user stories for chat, instant messaging, user-rank functionality, and the high score display for the Web subsystem functions.
You may benefit from completing research on the Internet and in the Capella library to learn how these functions are used in other gaming sites.
Assignment Instructions
Once you complete your preparation, create a 3-4 page professional paper in which you complete the following:
For this assignment, complete the following:
- Use the User Story Template linked in the Resources to create user stories (at least four) for the following functions:
- Chat.
- Instant messaging.
- User rank.
- High-score functionality.
- Create use-case diagrams for the user stories created for chat, instant messaging, user-rank functionality, and high-score display. A use-case diagram is a pictorial view of each user story.
- Choose an architectural style to complete the software architecture.
- Explain this style.
Microsoft Visio is provided through a Toolwire virtual desktop for your use to create the diagrams required for your assignment. Access the software via the Toolwire resources in this unit.
Refer to the User Stories Scoring Guide to ensure that you meet the grading criteria for this assignment.
Submit your assignment for faculty evaluation by clicking the linked assignment title. Unlike in other assignments, you are not required to submit this assignment to Turnitin before submitting it for faculty evaluation.
Here is an example of a user story.
Example
User story title: Customer withdraws cash.
As a customer,
I want to withdraw cash from an ATM
So that I do not have to wait in line at the bank.
Acceptance Criterion 1:
Given that the account is creditworthy
And the card is valid
And the dispenser contains cash,
When the customer requests the cash
Then ensure the account is debited
And ensure cash is dispensed
And ensure the card is returned.
Acceptance Criterion 2:
Given that the account is overdrawn
And the card is valid,
When the customer requests the cash
Then ensure the rejection message is display
And ensure cash is not dispensed.
