Abstract : A sample of over 61,000 maintenance reports was analyzed with respect to frequency of use of the how-malfunctioned codes. Approximately negative-exponential distributions of reported code frequencies were found, with the single most frequently used code accounting for 28.8% of all reports, the two most frequent codes accounting for 38.4%, and five codes accounting for 50.2%. 50% of the work centers used nine or fewer codes. The results of this study lend support to the desirability of substituting a mnemonic code for the current how-malfunctioned coding system. (Modified author abstract)
