daniels, porteny and urrutia et al make a good case for the idea that that public decisions ought to be made not only “in the light of” evidence but also “on the basis of” budget impact, financial protection and equity. health technology assessment (hta) should, they say, be accordingly expanded to consider matters additional to safety and cost-effectiveness. they also complain that most hta re...

Defects Control Charts for High-Quality Processes

Software quality processes can be assessed with the Orthogonal Defect Classification COnstructive QUALity MOdel (ODC COQUALMO) that predicts defects introduced and removed, classified by ODC types. Using parametric cost and defect removal inputs, static and dynamic versions of the model help one determine the impacts of quality strategies on defect profiles, cost and risk. The dynamic version p...

Software development is a complex process where many organizational units, persons, systems and artifacts are involved. In companies that exceed a certain size the business processes become difficult to handle and the quality of the product can decrease. A process-oriented view on software development is increasingly popular witnessed by current publications on the software development process ...

For processes concerning attribute data with (very) small failure rate p, often negative binomial control charts are used. The decision whether to stop or continue is made each time r failures have occurred, for some r ≥1. Finding the optimal r for detecting a given increase of p first requires alignment of the charts in terms of in-control behavior. In the present paper binomial charts are sub...

As defined by major dimensional metrology system users and suppliers, the Quality Information Framework (QIF) is an integrated and holistic set of information models which, if widely adopted, can enable the effective exchange of metrology data throughout the entire manufacturing quality measurement process – from design to planning to execution to analysis. This paper introduces the philosophy ...
