The chapter deals with the problems of information technologies’ quality aspects and their importance for the state and public administration, e-governance, and e-democracy. The concept of quality is defined, and it is demonstrated that for quality evaluation, the clarification of needs and specification of exact requirements represents a key problem. The chapter focuses on general quality management and specifically on quality of ICT-solutions. The ISO/IEC software product quality and data quality is thereafter briefly presented. The principle of quality evaluation based on the quality decomposition into several characteristics is also described along with the principles of measurement theory. Finally, this is supplemented by selected approaches for expert rating of trends for ICT-solutions having a direct impact on long-term quality prediction.
Chapter Preview


The international standards for quality management of the ISO 9000 series are well known and respected in the community of developers, suppliers, acquirers, and users of all product categories. However, these standards are general, and cannot reflect specifics of individual products including software products. These standards are primarily focused on the implementation of quality management systems for product developers, producers, suppliers and service providers, but only marginally for product acquirers and end users. They obviously cannot directly apply to the development process, and have often only limited information about it. The conformance of the development process with the requirements of the ISO 9000 series provides a certain level of product quality, but it cannot assure that all product attributes fit to particular user requirements. Accordingly, it is necessary to extend the general standard of the ISO 9000 series by standards for product quality evaluation based on specifics of individual types of products.
