Keen to know how you handle management of supply continuity risks. In particular, managing supply of key inputs. Let's say we already know who are the critical suppliers - is it just about finding an alternative supplier, or reviewing safety stocks, etc? Do you document this in a formal plan for continuity purposes (as almost all the time, these mitigating measures are in the heads of personnel involved)? How far do you go? Keen to know the practices out there. Thank you!
