I have used VSM for some 30 years but still amused that Policy cascade in UK government is from S5 to S1. have we woken up to the fact that S4, S3, S2 as well as S3* are now needed with the requisite feedback loops.
Perhaps more importantly do we need to design attenuation and amplification mechanisms and S3* to eliminate much of the communications noise and mixed messages re Covid 19?
