Satisfaction Level:
Ideally, DDS should target at satisfying all the requests it receives for the supply of the documents. However, in practice this target is not achievable even from the most comprehensive centralised collection. In general, a satisfaction level of 90-95 per cent is recommended and considered very good. A high satisfaction level depends not only on the availability of the required document in the centre that offers the service but also on the ability of the centre to locate and supply it from elsewhere in the world as quickly as possible.
