3.1 The concept of a regular Group `A' Service, the way it is constituted and its grade structure have been explained in the previous section. The various attributes of an ideal cadre structure of a Central Group `A' Service are elaborated in the following paragraphs with specific reference to the existing structures, their deficiencies, the need to rectify them through periodical reviews and the methodology of the review exercises.

The functional needs of a regularly constituted service ought to be fully met by cadre posts without having to take recourse to ex-cadre posts. Conversely, cadre posts should entirely cater to the functional requirements of the Service and should not be utilised for performing functions other those for which the Service is intended;

The grades into which the cadre is divided should be clearly distinct in the sonse that each carries a distinct level of responsibility within the functional area of the concerned service. The posts within a grade should also be inter-changeable;

The cadre structure should facilitate smooth mobility for its members both herizontally and vertically. Thus, while the posts in the same grade may be inter-changeable, any member of a grade should be capable of moving up and discharging the duties of a post in a higher grade;

An ideal cadre structure should be capable of fulfilling the legitimate career expectations of the member of the Service. In other words, the functional needs of a Service will have to be in harmony with the legitimate career expectations of its members; and

Every cadre structure should have separate provision for various types of reserves like probation, training, leave and deputation.
