In this paper we present a complete reference framework for the operation of Certification Service Provider as an organisation. The objective is to form an intermediate reference model, to which the CSPs will conform, towards the full compliance to the ISO-9000 quality standards. There are two dimensions of quality in respect of a CSP: The first quality dimension regards the value added securit...

Previous studies in software certification provide a set of axiom and supporting models for software assessment and certification. Two main researches were undertaken to study the issue of certification and developed models of software certification. These models have been developed using requirements-design-implementation strategy to ensure that it meets the needs of a number of different inte...

The fifth international workshop on Software Quality and Maintainability (SQM 2011) offered a forum to researchers to present their original work and to practitioners to relate their experiences on issues pertaining to software quality and maintainability. Moreover, the theme of the workshop invited discussion on how to bridge the gap between end user expectations, business requirements, vendor...

The goal of a data warehouse system is to provide a comprehensive overview of the data available in a company, thereby supporting the management decisions. The integration of data coming from heterogeneous sources is one of the key problems in data warehousing. The technical foundations for the integration have been developed in recent years. However, an efficient technical infrastructure is no...

Fulfillment of customer’s requirements alone is not enough to be competitive in today’s challenging market. Instead, blended value requirements need to be fulfilled for customer satisfaction, for efficient value process, and to achieve strategic goals including profit. On the other hand, ‘e-business modelling’ and ‘sustainability of the business’ are already established terms as e-business conv...

A quality perspective in data resource management is critical. Because users have different criteria for determining the quality of data, we propose tagging data at the cell level with quality indicators, which are objective characteristics of the data and its manufacturing process. Based on these indicators, the user may assess the data's quality for the intended application. This paper invest...

The quality of the results produced in the early phases of systems development is a major factor in determining the overall quality of an information system. Therefore, an important task for research in conceptual modelling and requirements engineering is to clarify the concept of quality and develop methods for improving the quality of conceptual schemas. In this paper, we propose an approach ...

This paper presents the emerging requirements users are imposing upon the evolving world of heterogeneous 4G mobile/wireless networks through their perception of final services. The mapping proposed in this paper groups together these user requirements in three main and distinguishable categories: service provision, connectivity, and adaptability and reconfigurability, by describing system conc...

Considerable progress has been made on the technical development of sensor networks. However increasing attention is now also required for the broad diversity of end-user requirements for the deployment of sensor networks. An expert survey on the user requirements and future expectations for sensor networks was carried out. Both technology and applications are seen as main drivers for sensor ne...

In this paper an action approach to requirements engineering is outlined. The approach is based on a language action view of information systems, organisations and business. Theoretical standpoints and methodological consequences are presented and elaborated. One conclusion is that requirements engineering ought to be viewed as actability engineering in order to perceive information systems as ...
