    19 F NMR chemical shifts in the literature vary strongly, commonly by over 1 ppm, even within the same solvent. [5] Although the reference compound for 19 F NMR spectroscopy, neat CFCl 3 (0 ppm), [6] has been used since the 1950s, [7] clear instructions on how to measure and deploy it in routine measurements were not present until recently.

    The following table shows the cost of fixing the defect depending on the stage it was found. [84] For example, if a problem in the requirements is found only post-release, then it would cost 10–100 times more to fix than if it had already been found by the requirements review.

    The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
