A working risk register you can use right now, in the browser. Add each risk, rate likelihood and impact, assign an owner, and see everything laid out on a heat map so the few that genuinely matter stand out from the many that do not. Nothing to install and no signup.
A single list of the things that could go wrong, each scored for how likely it is and how much damage it would do, with a named person responsible. The scoring is what turns a worry list into something you can act on.
Fewer than most people expect. Eight to fifteen actively managed risks beat a list of sixty nobody reads.
