Dear Nirmala,
I assume from your description of the case that you have designations like Assistant Executive, Junior Executive, Executive, Senior Executive, Assistant Officer, Junior Officer, Officer, Senior Officer, Assistant Manager, Deputy Manager, Manager, Senior Manager, and so forth.
You are looking at minimizing the job titles by eliminating either the designations containing the term 'officer' or 'executive' and having one common title for both categories.
When you are undertaking such an exercise, it is better to look at all the designations for the purpose of reducing the number of designations in the company and also for coming out with fewer layers in the organizational structure and possible broadening of salary grades in the future.
You can probably think of using the title 'Associate' in lieu of 'Executive' or 'Officer'. Also, eliminate the words 'Assistant', 'Junior', 'Senior', etc., from the job titles. Instead, you can have, for instance, titles such as - Associate-HR (Grade A), Associate-Materials (Grade C), Associate-Finance (Grade B), etc. The grades A, B, C, etc., need not be mentioned on the business cards of these employees or in any routine document except in the office order communicating the change of designation to the individual employees. This means, all are associates, but they know for themselves what grade they are in.
All the 'Officer' and 'Executive' designations could be replaced as above.
You may probably retain designations with the term 'manager' contained therein, but possibly reduce the levels like Junior, Assistant, Deputy, Senior, etc., if you have so many. Alternatively, anybody other than the manager or above, but in the categories from Junior Manager to Deputy Manager, could be redesignated as Senior Associate with appropriate grades followed by as in the case of associates.
For your information, in a reputed auto ancillary company in Chennai, all from Assistant to Manager of every department are designated as 'Members'. They carry designations like 'Member-Production', 'Member-HR'.
What I have given you are only a few suggestions, and you may have to choose a way that is acceptable to your top management.

Govardhan
