What you fail to see though is that the Holocaust in itself is part of a development process. It started with the Polizei-Bataillone and SD-units behind army lines, moved to widespread incarceration and ultimately to the erection of the first dedicated death camps in 1942 (Bełżec, Sobibor, Treblinka). This hints at the fact that the Holocaust was far from "efficiently" organised and, to a degree, not pre-planned in its final form with the invasion of Poland in 1939. Instead, changing circumstances lead to a change in organisation and thus ultimately to the Wannsee conference and the final stage of the Holocaust.
