Merits and Demerits
The point method is a superior and widely used method of evaluating jobs. It forces raters to look into all key factors and sub-factors of a job. Point values are assigned to all factors in a systematic way, eliminating bias at every stage. It is reliable because raters using similar criteria would get more or less similar answers. The methodology underlying the approach contributes to a minimum of rating error (Robbins p. 361). It accounts for differences in wage rates for various jobs on the strength of job factors. Jobs may change over time, but the rating scales established under the point method remain unaffected. On the negative side, the point method is complex. Preparing a manual for various jobs, fixing values for key and sub-factors, establishing wage rates for different grades, etc., is a time consuming process, According to Decenzo and Robbins, "the key criteria must be carefully and clearly identified, degrees of factors have to be agreed upon in terms that mean the same to all rates, the weight of each criterion has to be established and point values must be assigned to degrees". This may be too taxing, especially while evaluating managerial jobs where the nature of work (varied, complex, novel) is such that it cannot be expressed in quantifiable numbers.

Famous quotes containing the word merits:
“Since I know nothing of the merits of poetry, I am not able to pass any opinion upon this, but I can see that “reap” and “deep,” “prayers” and “bears,” “ark” and “dark,” “true” and “grew” do rhyme, and so I suppose it is a splendid effort, but if you had written it in plain prose, I could have understood it a great deal better and read it a great deal more easily.”
—Susan B. Anthony (1820–1906)
