192 Mullany and Lay<br />

n<br />

S = � s i w i,<br />

i = 1<br />

where:<br />

S = respondent’s overall satisfaction with n significant facets of the job,<br />

s i = respondent’s satisfaction with facet i, rated on a seven-point scale, and<br />

w i = the importance of facet i to the respondent, rated on a seven-point scale.<br />

Pearson made use of this model in his 39-factor instrument discussed earlier<br />

(Bailey & Pearson, 1983). However, the R-score method makes three fundamental<br />

departures in its application of the same. Firstly, it assumes that weighted<br />

responses to dissatisfaction with various facets of a system and its manner of<br />

implementation will give a valid measure of overall dissatisfaction. It is difficult to see<br />

why all the arguments which apply to weighted measures of satisfaction cannot also<br />

apply to its antipode, dissatisfaction, hence this variation was assumed valid.<br />

Secondly, the R-score method assumes that overall dissatisfaction gives a valid<br />

measure of its surrogate, user resistance. This stems directly from the discussion<br />

above so long as it is understood that only those forms of resistance variation were<br />

assumed valid. Secondly, the R-score method assumes that overall dissatisfaction<br />

gives a valid measure of its surrogate, user resistance. This stems directly from the<br />

discussion above so long as it is understood that only those forms of resistance<br />

measured by overt expressions of dissatisfaction are intended. Finally, the facets of<br />

dissatisfaction are not pre-specified, but are enumerated by the respondent (that is,<br />

the user) himself. This was justified in terms of Wanous and Lawler’s model by<br />

rating any complaint raised by the user with unit importance (and, of course, those<br />

not raised by the user with zero importance). This meant that the R-score could be<br />

measured simply by summing the user’s dissatisfaction ratings for his own complaints<br />

against the system. In mathematical terms, the R-score, R, after the user has<br />

made n complaints in respect of the system and/or its manner of implementation, can<br />

be expressed as:<br />

n<br />

R = � s i,<br />

i = 1<br />

where s i is defined as the severity of complaint i to the user, rated on the<br />

following seven-point scale:<br />
