Innovation drives productivity, and productivity is what drives jobs growth and the wealth that pays for our health, education, defence and social security systems. In short, innovation really matters. Governments, businesses and academics obsess over it. We need to know what works, what doesn’t and why - and that means turning to measurements and metrics. But can we really measure innovation today? Are we doing it right, or are our metrics more suited to Industry 2.0 and 3.0, rather than 4.0?
