Dear Friends,
as per my knowledge, Organisational Development subject, deals with appropriate tools application on the basis of analysis /survey of organisational diognis, through sample questionnarries and based on feedback of the members of the organisations. After thorough analysis, proper proven tools ( Interventions, OD Intervention ) applied to reslove the issues and through continuous monitroing the effectiveness of the intervention measured.
Where as HRD is a total fuction, helps to integrate human resourece, developement, evaluate the perforamcne etc. on which the sucess of the organisation depends upon.
i think both is important, by at large if HRD functions effectiveness is obtained, less the requirement of OD.
regards,
