RocReadaR : Quality Attributes and Constraints

Mobile Application Quality Attributes

Quality AttributeApplicabilityRealization PlanPriority
MaintainabilityMaintainability is important so that future developers can work on the application.The application will use javascript based frameworks consistently, so that all applications developed use the same technologies.HIGH
ScalabilityScalability of the application is relatively low priority. Being released as a mobile application will allow it to be released to many users at once. Scalability is much more import in the recognition server.The application will be released using standard mobile application platforms. Work that does not scale well will be offloaded to the recognition server.LOW
PerformancePerformance of the application is very important. Image recognition performance will be handled on the image recognition server, so the performance that is important is the application's responsiveness.Currently not handled by the Rock Raiders Team. Public Beta testing is expected to be performed by the RocReadaR main team.HIGH
UsabilityUsability is incredibly important to the customers, as it will be used by the users directly. This is of ever increasing importance with the growing expectations of mobile applications.Currently not handled by the Rock Raiders Team. Public Beta testing is expected to be performed by the RocReadaR main team.HIGH
SecurityCurrently not handled by the Rock Raiders Team. Currently not handled by the Rock Raiders Team.UNKNOWN
AvailabilityAvailability of the application is relatively low priority. Being released as a mobile application will allow it to be available almost 100% of the time.The application will be released using standard mobile application platforms.HIGH

 

Management Portal Quality Attributes

 MaintainabilityMaintainability is important so that future developers can work on the application.The application will use javascript based frameworks consistently, so that all applications developed use the same technologies.HIGH
ScalabilityScalability of the management portal is relatively low priority. Image recognition however, will require high scalability.The application will be hosted in a cloud platform. Scaling to more instances will remain an option in case it is required.LOW
PerformancePerformance is of medium importance. The application should be very usable, but it is not terrible if the publishers experience minor delays.The application will be hosted in a cloud platform. Scaling to more instances will remain an option in case it is required. Formal usability testing with both publishers and non-publishers will be performed in the middle of development, and slow sections will be identified.MEDIUM
UsabilityUsability is incredibly important to the customers, as it will be used by the publishers directly.Formal usability testing with both publishers and non-publishers will be performed in the middle of development.HIGH
SecuritySecurity is somewhat important, however it is not expected to be an issue. The main issues are standard web security issues and accidental release of publisher information and images.Standard security practices regarding user accounts and web technologies will be practiced. User access control levels will be implemented.MEDIUM
AvailabilityAvailability of the portal, while relatively easy to do, is important so that publishers can use the application when they need to.The application will be hosted in a cloud platform. Scaling to more instances will remain an option, and automatic restart configuration will be utilized if available. Development will begin in the cloud platform midway through development so stability can be analyzed.HIGH

 

Image Recognition Server Quality Attributes

MaintainabilityMaintainability is important so that future developers can work on the application.The application will use javascript based frameworks consistently, so that all applications developed use the same technologies.HIGH
ScalabilityScalability of the Image Recognition Server is exceedingly important. The application must be able to scale to 30,000 users.

Scalability will be achieved through a variety of important practices. First, the application will be hosted in an auto-scaling cloud platform. The application will be designed in a way that tracker files will be analyzed on the image recognition server. The tracker files will be organized in a fashion that will allow searching using the most relevant files first. Finally, if possible, the content returned from the image recognition server will be hosted on using a different service, and the image recognition server will send simply a reference to the secondary service.

Scalability testing will also be performed.

VERYHIGH
PerformancePerformance of the Image Recognition Server is exceedingly important.Performance will be achieved by using the tracker organization techniques described above, for scalability. Tracker files will be organized to allow searching using the most relevant files first. Keeping the app scalable will also make sure that even in high load, it will perform quickly.VERYHIGH
UsabilityNot applicable. The Image Recognition Server has no user interface. N/A
SecuritySecurity is of relatively low priority.The system must be able to handle denial of service attacks, and so any tools available from the cloud platform will be utilized. Files not allowed to be shown to the public by the publishers will have permissions in business rules to prevent access.LOW
AvailabilityAvailability of the Image Recognition Server is exceedingly important. Without the image recognition server, the mobile application would be useless.The application will be hosted in a cloud platform. At least 2 instances will be available at all times. Automatic restart configuration will be utilized if available. Development will begin in the cloud platform midway through development so stability can be analyzed.

VERYHIGH
