Building analogies always helps in terms of understanding
With regard to avalanche risk management, almost everyone now assembles their own cobbler's work according to the snow pusher's assessment - but hardly anyone is a trained cobbler or carpenter. And in practice, nobody actually uses the instruction manual (which corresponds to risk reduction methods) for assembling Ikea furniture. This works well with drifting snow problems and wet snow problems (bedside cabinets), less well with new snow problems (dressers) and almost not at all with old snow problems (built-in kitchen appliances).
As mentioned above, we live in 2017 - so what is the most common or most widespread method of avalanche risk management? 3x3, stop or go, w3 - or do you just stay at home until the end of February and then only go on a tour in the morning? Maybe for training tours, avalanche courses or Alpine Club tours. For private ski tours, however, it is and remains amateurish handicraft work, i.e. the chaotic screwing together of supplied parts and some from your own construction kit, but without enclosed and therefore easily available assembly instructions. What you have learned properly or have seen somewhere and understood straight away or have been able to understand and apply (also known as "A one-day course with lots of solidly interpreted experience") or perhaps have been explained to you by your brother-in-law's friend, flows into avalanche management in the winter mountains.
