In the Dorben Company, the analyst has installed a point job evaluation plan covering all indirect employees in the operating divisions of the plant. Ten factors were used in this plan, and each factor was broken up into five degrees. In making the job analysis, the position of shipping and receiving clerk was shown as having second-degree initiative and ingenuity, valued at 30 points. The total point value of this job was 250 points. The minimum number of points attainable in the plan was 100, and the maximum was 500.
a) If 10 job classes prevailed, what degree of initiative and ingenuity would be required to elevate the job of shipping and receiving clerk from job class 4 to job class 5?
b) If job class 1 carries a rate of $8 per hour and job class 10 carries a rate of $20 per hour, what rate does job class 7 carry? (Note: Rates are based on the midpoint of job class point ranges.)
