"At Google, we often think that speed is the forgotten 'killer application' – the ingredient that can differentiate winners from the rest. We know that the faster we deliver results, the more useful people find our service.

But in a world of accelerating change, we all need time to reflect. Think Quarterly is a breathing space in a busy world. It's a place to take time out and consider what's happening and why it matters.

Our first issue is dedicated to Data – amongst a morass of information, how can you find the magic metrics that will help transform your business? We hope that you find inspiration, insights, and more, in Think Quarterly.
