It's quite obvious in German literature how the Eastern Front experiences influenced the final offensives against Italy and France:

Bruchmller became famous after the breakthrough at Riga and his brand of breakthrough artillery support proved itself on the Eastern Front.

The Brussilov offensive initially featured several highly effective tactics, and delivered a demonstration of what was at the same time being developed in by the German army on the Western front in limited attacks.

The large-scale advances in the East reawakened the belief of the OHL in the possibility of manoeuvre past the breakthrough.

The success against Italy in the final offensive (half of Italian army was ruined) again confirmed and convinced; the breakthrough and exploitation happened in a high force density battle, more reminiscent of the Western front than almost anything in the East. Equipment and ammunition supply of the Italians were also more Western Front-like. Success was achieved with relatively modest advances, so the problem of supply past the railheads did not seem as importnat as it turned out to be in 1918.


The British forces' learning was particularly poor in regard to the defensive system, since they hadn't been on a large-scale defence since 1914 and the typical German limited attack provoked exactly the opposite defence as required to stop a large-scale offensive without excessive losses (the dilemma about how many forces shall be exposed in the forward defences to stiffen them).
