Chris Collision, in this recent post of his Failure to learn talks about the UK Government's response to Covid-19 and makes the case that the Government failed to learn from experience.
Another way of looking at it is that much of the knowledge was there, but people failed to act.
Either way, it demonstrates that we need Knowledge Management more than ever.
Furthermore, in light of this article Senators sold millions of stock before the coronavirus crash, I have added the following reason to my post as to why knowledge is not power.
And then, sometimes, people act on the knowledge they have, not for the benefit of the whole but for selfish purposes and fail to share it more widely.In this case, you may still consider knowledge to be power but knowledge alone, does not guarantee people will do the right thing.
