Mapping General System Characteristics to Non- Functional Requirements

The Function point analysis (FPA) method is the preferred scheme of estimation for project managers to determine the size, effort, schedule, resource loading and other such parameters. The FPA method by International Function Point Users Group (IFPUG) has captured the critical implementation features of an application through fourteen general system characteristics. However, Non- functional requirements (NFRs) such as functionality, reliability, efficiency, usability, maintainability, portability, etc. have not been included in the FPA estimation method. This paper discusses some of the NFRs and tries to determine a degree of influence for each of them. An attempt to factor the NFRs into estimation has been made. This approach needs to be validated with data collection and analysis.Comment: 5 page

Requirements Prioritization Based on Benefit and Cost Prediction: An Agenda for Future Research

In early phases of the software cycle, requirements prioritization necessarily relies on the specified requirements and on predictions of benefit and cost of individual requirements. This paper presents results of a systematic review of literature, which investigates how existing methods approach the problem of requirements prioritization based on benefit and cost. From this review, it derives a set of under-researched issues which warrant future efforts and sketches an agenda for future research in this area

A cognitive approach to improve software engineering processes

Cognitive Informatics is a new research area that combines concepts from cognitive sciences and informatics. Particularly, classification according to cognitive styles or learning styles is a common practise in educational and business areas in order to obtain better performance from people involved in learning and collaborative tasks. Humanintensive processes in software engineering make it similar to those areas. In this paper, we propose using a kind of people classification to improve those processes of software engineering where human behaviour is a critical influence on their success.Eje: Ingeniería en SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Crosscutting, what is and what is not? A Formal definition based on a Crosscutting Pattern

Crosscutting is usually described in terms of scattering and tangling. However, the distinction between these concepts is vague, which could lead to ambiguous statements. Sometimes, precise definitions are required, e.g. for the formal identification of crosscutting concerns. We propose a conceptual framework for formalizing these concepts based on a crosscutting pattern that shows the mapping between elements at two levels, e.g. concerns and representations of concerns. The definitions of the concepts are formalized in terms of linear algebra, and visualized with matrices and matrix operations. In this way, crosscutting can be clearly distinguished from scattering and tangling. Using linear algebra, we demonstrate that our definition generalizes other definitions of crosscutting as described by Masuhara & Kiczales [21] and Tonella and Ceccato [28]. The framework can be applied across several refinement levels assuring traceability of crosscutting concerns. Usability of the framework is illustrated by means of applying it to several areas such as change impact analysis, identification of crosscutting at early phases of software development and in the area of model driven software development

A Formal Knowledge Level Process Model of Requirements Engineering.

In current literature few detailed process models for Requirements Engineering are presented: usually high-level activities are distinguished, without a more precise specification of each activity. In this paper the process of Requirements Engineering has been analyzed using knowledgelevel modelling techniques, resulting in a well-specified compositional process model for the Requirements Engineering task

An Object-Oriented Software Model for Students’ Registration and Examination Result Processing in Nigerian Tertiary Institutions

The principles of Object-Oriented Software Engineering are employed to model a software application known as Undergraduate Registration and Examination Processing System (SPERU) for Nigerian Tertiary institutions. Rapid Application Development (RAD) tools are utilized in its implementation to achieve an excellent software system. SPERU is herein presented , as a typical instance of a well modelled software system, that testifies to the beauty, power and supremacy of the Object-Oriented paradigm The result of applying software predictor metrics indicates that SPERU is reliable and elegant
