This report is aimed at the description of process based method for improving data quality. In particular, an architecture that periodically evaluates data quality in internal databases and in all relevant business processes is described. This requires techniques for measuring data quality and rules to manage data when quality does not meet requirements. Cases in which data do not meet users re...

Achieving optimal production cycle time for improving manufacturing processes is one of the common problems in production planning. During recent years, different approaches have been developed for solving this problem, but most of them assume that mean quality characteristic is constant over production run length and sets it on customer’s target value. However, the process mean may drift from ...

In this article, a novel acceptance-sampling plan is proposed to decide whether to accept or reject a receiving batch of items. In this plan, the items in the receiving batch are inspected until a nonconforming item is found. When the sum of two consecutive values of the number of conforming items between two successive nonconforming items falls underneath of a lower control threshold, the batc...

• Statistical process control (SPC) is a management philosophy that relies on straightforward statistical tools to identify and solve process problems. • By systematically identifying potential problems in process control, managers can proactively make corrections before quality outcomes suffer. • SPC methods are useful in helping managers to measure whether their processes and products conform...

If organizations wish to achieve continuous quality improvement they need to use appropriate selection of quality tools and techniques. In this paper a review of possibilities of the systematic use of seven basic quality tools (7QC tools) is presented. It is shown that 7QC tools can be used in all process phases, from the beginning of a product development up to management of a production proce...

Process model matching refers to the task of creating correspondences among activities of different process models. This task is crucial whenever comparison and alignment of process models are called for. In recent years, there have been a few attempts to tackle process model matching. Yet, evaluating the obtained sets of correspondences reveals high variability in the results. Addressing this ...

Process assessment and process improvement are both very difficult tasks since we are either assessing or improving a concept rather than an object. A quality process is expected to produce quality products efficiently. Most of the existing models such as CMM, ISO 9001/9000-3 etc. intend to enhance the maturity or the quality of an organization with the assumption that a matured organization wi...

Most traditional businesses operate in a local or national environment, and therefore, changes in transnational parameters do not affect them in a direct way. Being inherently global in nature, electronic commerce (ecommerce) needs quality and process standards from broader and multiple perspectives. As an effort to expand the utility of ecommerce systems to both businesses and consumers, we pr...

Data is produced and consumed everyday by information systems, and its inherent quality is a fundamental aspect to operational and support business activities. However, inadequate data quality often causes severe economic and social losses in the organizational context. The problem addressed in this paper is how to assure data quality, both syntactically and semantically, at information entity ...

In the past, ISO 9001:1994, ISO 9002:1994 and ISO 9003:1994 were the standards used for certifying production organizations, but seldom in educational institutions, although it concerns the quality of products and service. The new standard ISO 9001:2000 introduces process approach to quality management. Definitions for quality in education, and examples of processes, according to ISO 9001:2000,...
