SRP Example: Failure Alerts


The solution should alert of disks close to their capacity .

In case of a network or server disk crash, the solution should alert immediately.

The system should alert the administrator of the resources (physical or logical) close to their capacity.

failuresSet : set of possibleFailureso possibleFailures: server crash | disk crash …

The system shall trigger alerts in case of failuresSet failures.

Title: Requirement Patterns Search and Recommender System Description: PABRE-Proj is a tool that helps Requirement Analysts during the elicitation and specification of requirements. This tool is based in the use of Software Requirement Patterns (SRP), which are collected and stored in an SRP Database. This work consists on developing new functionalities for the PABRE-Proj tool that allow searching SRP in the database and developing recommender functionalities to the RA. The recommendations will be based on the previous SRP applied during elicitation and relationships and categorization of SRP that are necessary to be added to the SRP database schema.

Title: Development of web services for the PABRE-Proj tool. Description: PABRE-Proj is a tool that helps Requirement Analysts during the elicitation and specification of requirements. This tool is based on the use of Software Requirement Patterns (SRP), which are collected and stored in an SRP Database. This work consists on developing web services to allow Requirement Management Tools (RMT) to access data and functionality that PABRE-Proj provides. Specifically, these RMT should be able to access the requirements in a project and the classification schema of these requirements, and also to search for an SRP. In order to test the optimal behaviour of the web services, an interface will be also developed.

Title: Development of a Requirements Management Tool on Android. Description: This work consists on developing a simple intelligent editor that may help a Requirements Analyst during elicitation of requirements. During the edition of new requirements, the editor will search in a glossary of requirements engineering terms and in a Software Requirements Pattern (SRP) database, and will propose changes in the wording of the requirements in order to improve the consistency and quality of software requirements specification documents.Technologies: Android, Web Services, Java, Hibernate, DerbyContact: Carme Quer ([email protected])Web: http://www.upc.edu/gessi/PABRE/index.html

Title: Analysis and Improvement of the Usability, Maturity and Interoperability of PABRE. Description: The PABRE system is composed of two tools: PABRE-Proj and PABRE-Man. This work consists on performing a detailed and rigorous analysis of the usability and maturity of each one of these tools, and also the interoperability between them. Once identified the possible aspects to improve, they will be implemented.Technologies: Google Web Toolkit (GWT), Java, Hibernate, DerbyContact: Carme Quer ([email protected])Web: http://www.upc.edu/gessi/PABRE/index.html

Title: Construction of Requirement Patterns for an Specific Domain. Description: This work is implemented in two phases. First, to study one software or services domain; for instance: the Cloud Computing services domain. Once studied, Software Requirement Patterns (SRP) for the elicitation of products or services on this domain will be defined. This is a work that does not include any implementation. The construction of SRP will be made by analyzing information sources found in the Internet, eventually some requirement specification coming from real projects, and using analysis information tools as ATLAS.TI. Once defined, the SRP will be introduced in a SRP database through the PABRE-Man tool.Technologies: ATLAS.TI, PABRE-ManContact: Carme Quer ([email protected])Web: http://www.upc.edu/gessi/PABRE/index.html
