This paper aims to develop an object-based total quality reference model for various perspectives of heterogeneous stakeholders, which is able to completely define the quality of a distance learning system. The proposed model is a multilayer framework that is stratified by an abstract model, quality categories, super quality classes, sub-super quality classes, and attributes. Through back-forwa...

Practical prover interfaces are sizeable pieces of software, whose construction and maintenance requires an extensive amount of effort and resources. This paper addresses the engineering aspects of such developments. Using non-functional properties as quality attributes for software, we discuss which properties are particularly relevant to prover interfaces and demonstrate, by the example of th...

Architects use a variety of techniques to evaluate designs to determine the degree to which a product produced from the architecture would possess the desired levels of specific quality attributes. Reasoning frameworks are used to guide architecture definition by predicting the extent to which a software architecture satisfies its quality requirements. There has been much research about such di...

We involved 30 customers of a company designing and producing microwave ovens. In a number of experiments these customers generated over 100 new ideas on functions, attributes and services related to microwave ovens. The 21 best ideas were identified by company specialists and these ideas were then evaluated by a large customer group using the theory of attractive quality in order to identify w...

A hedonic price function for wine is estimated using Swedish data, 1989-91. Implicit prices for quality attributes are determined not from a regression of variety price on a vector of quality attributes, but rather from a regression of quantity sold (adjusted for weeks of availability) on price and quality attributes. Such a ‘reduced form’ is justified by the assumption that prices and attribut...

A set of waxy (amylose-free) experimental spring wheats (Triticum aestivum L.) of diverse parentage were grown, along with two nonwaxy and two partial waxy check cultivars, at diverse North American cultural environments. Grain yield and functional attributes of derived flours were determined. Average grain yield of the waxy lines did not differ significantly from the average yield of the check...

Objectives The objective of this research is to characterize biological, physical and chemical soil quality parameters and monitor their changes over time in minimum tillage and no-till seeding systems as affected by tillage, crop species and management systems to identify soil quality attributes that can be used in the development of best management practices for conserving soil quality and en...

Most formal assessment and evaluation techniques and standards assume that software can be analysed like any physical item. In safety-critical systems, software is an important component providing functionality. Often it is also the most difficult component to assess. Balanced use of process assessment and product evaluation methods is needed, because lack of transparency in software must be co...

This study is designed to explain how restaurant healthy food quality is related to repeat patronage intention. The results indicate that perceived value mediates the positive relationship between the restaurant healthy food and revisit intent. In other words, restaurant healthy food quality increases perceived value in the diner’s mind, which in turn results in a higher level of revisit intent...

The nature of system properties, sometimes called the new “ilities” are discussed, and defined, with particular attention to the differences between the ilities, formalized specification for the ilities, as well as relationships between the ilities. Examples are given including generalized statements about the “ility” of a system, as well as specification statements for requirements definition ...
