Attributes and methods are the basic contents of an object-oriented class. The connectivity among these class members and the relationship between the class and other classes play an important role in determining the quality of an object-oriented system. Class cohesion evaluates the degree of relatedness of class attributes and methods, whereas class coupling refers to the degree to which a cla...

This paper introduces a structured goal-oriented agent-based process modelling framework, where advanced requirements engineering techniques are combined with software quality modelling approaches, to provide an environment within which the stakeholders and the analysts can easily cooperate to discover, verify and validate the new IT system requirements. It forces and assists the stakeholders, ...

Measurement and improvement of e-service quality is important for sustaining competitive advantage of an e-commerce web site. A number of e-service quality measures have recently been developed that predominantly rely on the subjective evaluation of diverse quality attributes. To increase the objectivity of e-service quality measurement a recently developed measure of e-service quality has been...

MOTIVATION The process of producing microarray data involves multiple steps, some of which may suffer from technical problems and seriously damage the quality of the data. Thus, it is essential to identify those arrays with low quality. This article addresses two questions: (1) how to assess the quality of a microarray dataset using the measures provided in quality control (QC) reports; (2) how...

Software architecture evaluation plays an important role in the validation of quality models of software systems. This paper is based on the research carried out where the Architecture Trade-off Analysis Method (ATAM) was used. ATAM was chosen and used because it provides insight into the way quality attributes are mapped onto architecture and also shows the trade-offs existing between the iden...

The relative potential of various technologies for the confirmation of food authenticity and quality are discussed. Techniques that have found new applications in the field of quality assurance since 2001 are discussed in terms of their potential ease of application in an industrial setting. The use of specific techniques with chemometric analysis for the classification of food samples based on...

QbD is a systemic approach to pharmaceutical development. It means designing and developing formulations and manufacturing processes to ensure predefined product quality. Some of the QbD elements include defining a target product quality profile, designing product and manufacturing processes, identifying critical quality attributes, process parameters, and sources of variability and controlling...

We present a tool, called POIESIS, for automatic ETL process enhancement. ETL processes are essential data-centric activities in modern business intelligence environments and they need to be examined through a viewpoint that concerns their quality characteristics (e.g., data quality, performance, manageability) in the era of Big Data. POIESIS responds to this need by providing a user-centered e...

The popularity and growth of the "Information SuperHighway" have dramatically increased the number of information sources available for use. Unfortunately, there are significant challenges to be overcome. One particular problem is c o n t e x t interchange, whereby each source of information and potential receiver of that information may operate with a different context, leading to largescale s...

Early estimations and predictions of software quality attributes are essential to be in control of software development and to allow for delivery of software products which fulfil the requirements put on them. This paper focuses on a method enabling estimation and prediction of software reliability from the specification and design documents. The method is based on dynamic analysis of a well-de...
