The data delivery service currently ooered in the Internet is a point-to-point best eeort service. Work is underway in various IETF (Internet Engineering Task Force) working groups to include new services for applications that require a speciic quality of service. Examples of such applications include the so-called real time applications such as audio and videoconferencing, distributed interact...

Quality engineering uses robust design in order to improve quality by reducing the effects of variability. Variability of the product can be reduced by two stages. One is parameter design which is adjustable to the nominal value so that output is less sensitive to the cause of variability. Other one is tolerance design which is to reduce the tolerance in order to control variability. All costs ...

K R Balachandran is Professor of Accounting at the Stern School of Business, New York University and Bin Srinidhi is Associate Professor of Accounting at the Graduate School of Management, Rutgers University. Growing competition from foreign companies, notably from Japan, has resulted in increased attention being paid to cost and quality issues in the US. The traditional view is that improvemen...

Kelley Sobel, Computer Science and Systems Analysis Department, Miami University, Oxford, OH 45056, [email protected] Abstract—Evolving accreditation standards require that software engineering programs, and perhaps even individual courses, demonstrate that studen...

This paper offers an extrapolation of the manufacturing and service industries' Cost of Quality Model to the business of software development. The intent is to provide a theoretical account of the changing quality cost structure as a function of a maturing software development process. Thus, the trends in expenditures due to the four major quality cost categories --appraisal, prevention, intern...

The emergence of online paid micro-crowdsourcing platforms, such as Amazon Mechanical Turk (AMT), allows on-demand and at scale distribution of tasks to human workers around the world. In such settings, online workers come and complete small tasks posted by an employer, working for as long or as little as they wish, a process that eliminates the overhead of the hiring (and dismissal). This flex...

In this report methods to evaluate the costs of non-quality are studied. It is possible to associate with this measurement an economic evaluation of data value. Different components of total costs will be considered, both organizational and related to data management.
