[hdm] ÂWith respect to #17472: It is not correct to state that a measurement is a single data point. See e.g.ÂHubbard, Douglas W., How to Measure Anything, Finding the Value of âIntangiblesâ in Business, John Wiley & Sons, New Jersey, 2010. His main point is, that, in business measurements, just point measures aren't good measures. Often the point measure is not known or is not 100 % trustable. It is very important to be able to state measurement (so the result of measurement) as something that resides in a confidence interval, according to a certain level of confidence. ÂA measurement can be a point value. But it should also be possible to state a measurement as e.g. a confidence interval, with a confidence value. So-far about confidence interval and confidence. Now about distribution (stochastic distribution): A Monte Carlo measurement (i.e. outcome of Multi Carlo simulation or experiment) is typically expressed as a set of values that can be best described by a distribution curve. Stochastic enabling of measurement is important. But the distribution itself can not very well be defined as part of the measure, because the measure is re-usable in different contexts, and the distribution will often be specific to that context.   With respect to #17473: Each of these types seem to be categories of measures. Perhaps SMM should include some built-in measure categories such as Estimators, Simulators and Benchmarks. [hdm] ÂWith respect to #17473: It is not about the measure, but about the observation. It is about a specification the type of the observation. Note that the same measure can be used for for estimated measurement, as-is measurement, simulated measurement.  With respect to #17474: Measures can be equated. If there are multiple, equally good direct measures for a given characteristic then they are be directly associated by the measure equivalence relationship. [hdm]ÂWith respect to #17474.ÂThis is not about equivalence. ÂIt is like method overloading in Java ... When the same direct measure is applied in different contexts, slightly different or additional arguments (parameters) might be required in its operation. So, actually, more than one operation would be required. During discussions with Alain Picard this came out as the best solution.  With respect to #17475: Iâm good with this.   From: Juergen Boldt [mailto:juergen@omg.org] Sent: Friday, July 13, 2012 10:59 AM To: issues@omg.org; smm-rtf@omg.org Subject: issues 17472 - 17475 -- SMM RTF issues  This is issue # 17472ÂÂÂFrom: Henk de Man
