dc.description.abstract | The main goal of the study is to overcome the problems of traditional quality
models by developing a higher level conceptual framework, called the quality
meta-model, to assist in modelling quality of information systems as end
products of the development process. The aim is also refine the definition of
information system quality and quality requirements. As a by-product the
study presents principles of using the proposed meta-model as a governing
element in system development process. The main research question concerns
the validity of the conceptual framework. The approach is a combination of
conceptual analysis, theory-creating and theory-evaluating research. In addition
to an initial literature review and references to relevant writings, the research
activity comprises three quality modelling case studies in East-Africa.
Constructs found through a selective literature review are first generalized and
combined into a conceptual framework. Thereafter this initial meta-model is
used in case studies as a template for system specific quality models. Based on
findings and further literature review the conceptual framework is eventually
developed into its final form. The study shows that a comprehensive metamodel,
needed to fully account for information system quality, is a hybrid
model that in addition to the core quality elements includes parts from the
development process, system and context models. The quality of an information
system is in the first place determined by the existence and intensity of certain
desired relationships, or state of affairs, between the system and its context.
These requirements have priority over others that can be derived from the
former. A system specific quality model is the driving force of development.
The three case studies support the general validity of the proposed quality
meta-model through the usefulness and comprehensibility of the quality
models created on basis of it. It proved also to be general and flexible enough to
be applied in three different contexts. Comparison to traditional quality models
and newer alternatives, in turn, proves the meta-model’s comprehensiveness. | en |
