Concerto have been appointed to shape and deliver an interesting piece of strategic thinking with the National Audit Office. Our brief is to examine how different departments engage with their respective markets and come up with a repeatable Evaluation Model that can be used at intervals in the future. We drew three experts from our talent pool for this study, who understand the way government engages and procures services from different market places. The exam question is identify good practice and make recommendations that would help departments engage more effectively in the future. Interesting and challenging stuff.
