Dear,
In the language of compensation management, it is known as Broad Ranges. The figures shown in the question are the basic salary. With upward elevation, promotion, or increment, an employee will achieve the next higher basic. Such a structure is designed to differentiate the skills and experience of each employee, and this structure maintains the harmony of compensation paid to the employees. Generally, well-organized organizations create such a compensation structure. Each slab of progression is placed against the grade. It starts with the minimum basic being achieved by an employee in that particular grade and ends with the highest basic in that particular grade.
To arrive at this kind of salary progression structure, a lot of work/study is done, such as understanding the present compensation structure of the organization, comparing the structure with the industry, and finally comparing the structure with the competitors of the business and the capacity of the employer to pay. Once all these steps are completed, the mean, standard deviation, and bell curve of each of the compensation components are prepared to make decisions on the salary progression under each grade.
Regards,
