This time I won’t be going for a run at precisely the time that symptoms from the Covid vaccine are most likely to occur!

Again, the process of being invited, briefed, jabbed, and sent home was painless and while I’m really pleased with that, it highlights the difference between complex and complicated problems.

Co-ordinating a national vaccination program is complicated. There are a lot of moving parts and people to align, but drawing on expertise and processes moves us through the difficulty.

Getting people to want to be vaccinated is a complex problem. People that were onboard today might not be onboard tomorrow, given a ministerial misstep apparently unrelated to the issue at hand.

Complex problems require different thinking to solve them.

And, perhaps, better behaviours.
