 the full measure uses interview or observational techniques to establish current and expected levels of need in each domain . 
 the measure can be linked to routine indicators to provide an indirect approach to monitoring the value of services in which we identify the potential value that could be delivered by a service or intervention : capacity for benefit ; and the degree to which that value is actually delivered through a measure of quality.results and conclusionswhile ongoing work is developing the measure , previous versions have proved reliable and been successfully applied across client groups in a variety of contexts.discussionthe results suggest that the measure should provide a theoretically grounded method of reflecting the full value of social care .
