§ Norman Lamb
To ask the Chancellor of the Exchequer (1) what formula is being used to measure(a) annual efficiency gains and (b) savings of running costs within his Department in order to meet the targets outlined on page 75 of the HM Treasury departmental report 2002; 
(2) if he will make a statement on why it has not been possible to measure aggregate Treasury output, as mentioned on page 75 of the HM Treasury departmental report 2002. 
§ Ruth Kelly
The Treasury monitors those outputs which can be measured, such as replies to parliamentary questions, letters or other communications with the public, payment performance, and so on. However the Treasury's primary output is policy advice. Such outputs are difficult to measure and without a measure of overall output it is not possible to measure efficiency.
