I think the hardest thing has been that this is a change program. Ultimately we're trying to change thousands of decisions being made across any given year in departments. My relatively small team needs to reach out to the people taking those decisions—for each decision, there may be a group of several people taking that decision—and influence them. We're operating at a distance.
My feeling is that it's getting that message out there, and combining both carrots and sticks to make sure people change their mindsets. Similarly, it's ensuring that with the phrase we're using, “government is open for business”, SMEs understand we really are changing our ways, becoming less bureaucratic and easier to do business with. That is also sometimes challenging.
