Application of measurement criteria in the selection of interactive computer services
Paul D. Amer · 1980
This publication emphasizes the data analysis component of the computer service selection process.A computer service selection model, introduced in NBS Special Publication 500-44, is presented and three binary type selection procedures applicable in the measurement phases of that model are given.A binary type procedure determines which competing computer services perform above and which perform below a specified performance level.Those services determined to perform below a specified performance level can be eliminated or penalized depending on whether the performance specification is mandatory or desirable.The procedures explicitly specify prior to measurement an appropriate decision rule and/or the number of test (+) In some cases a correlation problem is unavoidable.The author is developing procedures which take correlation into account
