Step 3: Sub-Grading
Grading provides an organization with a maximum of 12 grades, which may not differentiate relative worth adequately. In such cases, the decision band method provides for sub-grading grades based on ranking.
Sub-grading involves assessing the relative difficulty, complexity, and skills required of the job in comparison to the other jobs within the same Band and Grade. The factors used to measure such concepts include
- Extent of knowledge required to complete tasks
- Hard skills required for completing job tasks
- Soft skills such as communication skills and customer service skills required for completing job tasks
- The extent of time pressure the job involves
- Mental effort required such as alertness and concentration
- Extent of physical activity required for the job
- Need for care and precision in the job
- Working conditions
Such factors are measures using a scale and added up to rank jobs.
For instance, between two data processing jobs within the same grade, one job may involve multitasking, and greater alertness and concentration, whereas the other may be relatively easy. Applying sub-grades allow ranking without subjective judgments.
As a rule of thumb, each lower grade has three sub grades and each upper or higher responsibility grade has two sub grades. There is however, no set or fixed number of sub-grades, and organizational requirements decide the optimal number.
