Pilots always work out — that’s rarely the problem. People enjoy them. But the hard part comes afterwards, when you want to implement something more broadly. We are an organisation of 10,000 people, so for something like rejuvenation cream for asphalt — one of our longest-running innovations — 11 different frameworks, working methods and guidelines had to be adapted across 5 different organisational units. That’s when you feel how hard scaling an innovation really is. People are always a little hesitant, and partly I understand that hesitation, because we’re talking about our road network. You notice that certain departments aren’t happy about it — but at some point you have to say together: OK. Someone just needs to decide. Having heard this, having heard that — we’re going left or we’re going right. That is genuinely a challenge for us. Who ultimately decides when there are different opinions in the organisation? You really need an owner of an innovation who has the mandate to say yes or no, left or right. And right now, that is too rarely the case.
