Quality Requirements and Standards
In the debate over new models for QC, keep your eyes wide open. Sometimes the desire for something new and different blinds you from seeing the strength of the present.
A key part of the ongoing debate about measurement uncertainty and allowable total error hinges on how we talk about bias. Is bias just another uncertainty like imprecision? Or is it truly a shift, a linear change that cannot be included in uncertainty calculations? Recent metrological approaches have attempted to fudge the answer to this question. But it's time to tackle it head on.
Part 3 of a continuing disucssion about of the current debate on quality, performance specifications, measurement uncertainty, and the meaning of life.
Part 2 in a discussion of the state of debate around quality, performance specifications, measurement uncertainty, and the meaning of life.
After nearly 8 years of building the new EFLM biological variation database, the recommendations for anaytical quality specifications have been adjusted downward. Desirable specifications are too demanding. What should labs do instead? The minimum.
