Evidence is critical to good public policy advice. GHK has experience of applying sound research methods: individual, household, consumer and business surveys; focus groups; stakeholder interviews; case studies with triangulation; expert panels; literature reviews; ‘mystery shopping’ and analyses of administrative information and secondary sources. Assignments include research working with employers, policy makers, ‘hard to help’ groups, children and young people, and the use of sensitive information. GHK’s approach to research meets the highest standards of rigour whilst recognising the need for ‘real world’ conclusions.
