Thank you for your answer.
I will go further. Since we started this discussion, I feel that everyone is coming to some kind of consensus that the supply chain problem was predictable. The causes were identifiable, in that the problems are now occurring in the form of a major crisis, but we will not necessarily be able to find short-term solutions, because we are dealing with a backlog of problems.
Despite the apparent consensus on the need to take a long-term view and the fact that changes will take time, are there short-term measures that can be taken to improve the situation?
