The Object-oriented Analysis - OOA - Essay Example The School of Technology at Oxford Brookes University is undertaking the computerization of the process for preparing question papers for its various departments. The process involves communication between the Examination and Conferment Unit (ECU), module leaders, teaching staff, internal checkers, the exam secretary, and external examiners. The computerization project aims to improve the current system, which is considered quite tedious by the different parties involved. The new system, which shall be named â€Å"School of Technology Modular Examination and Coursework Preparation† (STMECP System), must address the issues associated with the current system while meeting quality assurance requirements in the preparation of question papers. An initial Requirements Elicitation and Specification has already been conducted. The project team elicited and analysed users’ requirements for the new system and identified both functional and non-functional requirements, as well as identified and analysed use cases and scenarios. The next step is to produce detailed requirements specifications using requirements modeling tools which help control the complexity, risk, and scope of the project. Requirements modeling also help and define goals and success criteria in an unambiguous manner for all the parties involved in the development and eventual use of the system. Complex requirements can be modeled with full traceability provided from each requirement, through to the final deliverables and system behavior (Sparx-Req Mgt, 2008). As defined during Requirements Elicitation and Specification, the functional requirements of the new system are divided into two areas: 1) the preparation of questions, solutions and other exam and coursework materials, and 2) the preparation and update of the TEO forms.Use cases are goal-oriented sets of interactions between actors and the system. For the STMECP system, the actors are the exam secretary (ES), module leaders (ML), memb ers of the teaching staff (TS), internal checkers (IC), and external examiners (EE).
