OThe next 20% consume 20 % of financial resources (Group B) andOremaining 70 % items account for just 10% of the budget (Group C). VED analysis is based on the criticality of an item. O"V" is for vital items without which a hospital cannot function, O"E" for essential items without which an institution can function but may affect the quality of the services andO"D" stands for desirable items, unavailability of which will not interfere with functioning.(Refer: style="font-family:Cambria;font-size:13px;"> and Immunization Handbook for medical officers)
