One of the fun things with SEI Capability Maturity Model is that you reach level 1 just by having your process written down at all, no matter how stupid it sounds.
But the giggle test is just something I borrowed from business, which is, “can I say this with a straight face?” Which eliminates a lot more censorious than you would think. Writing something down is one thing, making eye contact with someone while repeating it is a bit harder.
censorious appears to mean 'severely critical of others'. I expect they meant 'censoriously', with the full intent being that the embarrassment felt by the critical reactions of others when reading the instructions out loud will cause you to eliminate or fix obviously broken, complex or tedious processes that you had, until then, just quietly been putting up with.
