<p>UK Trade & Investment (UKTI) uses its Performance and Impact Monitoring Surveys (PIMS) to measure the performance and impact of its support. The PIMS evidence is periodically complemented by independent impact evaluations, for the most recent example see</p><p>http://www.ukti.gov.uk/download/123593_174060/UKTI%20Response%20to%20Evaluation%20of%20the% 20impact%20and%20cost%20effective.html</p><p>PIMS covers all significant customer-facing trade services and provides evidence about service quality and what differences UKTI makes to businesses. It uses a range of measures, including information on the overall performance of UKTI against its performance measures. These results are provided at a regional level on a quarterly basis, more information can be found on the UKTI website:</p><p>http://www.ukti.gov.uk/uktihome/aboutukti/ourperformance/performanceimpactandmonitoringsurvey/quarterlysurveys.html</p><p>The robustness of UKTI's monitoring system was recognised by the National Audit Office in the conclusions of their 2009 value for money study of UKTI trade services, the full report can be found here:</p><p>http://www.nao.org.uk/press-releases/uk-trade-investment-trade-support-2/</p>
