The mechanism we have arrived at, which seems to work well, is one that looks to identify the shape of issues as early as possible and to get them sufficiently clear so that the relevant party can start proactively doing something about them before the investigation is even complete.
Now there’s some solid gold “tautological rubbish”.
We jump to an early conclusion and then complete an investigation. Having identified the ‘shape’ of issues early, we don’t need to investigate matters that might not support our early conclusion.
It seems to work well because the investigation invariably finds material to support the early conclusion.
