Hindenburg and Ludendorff demanded domestic changes to complement their new strategy. German workers were to be subjected to an Auxiliary Service Law () that from November 1916, subjected all Germans from old to compulsory service. The new programme was intended to create a trebling of artillery and machine-gun output and a doubling of munitions and trench mortar production. Expansion of the army and output of war materials caused increased competition for manpower between the army and industry. In early 1916, the German army had in recruit depots and another in March when the 1897 class of conscripts was called up. The army was so flush with men that plans were made to demobilise older classes and in the summer, Falkenhayn ordered the raising of another for an army of The costly battles at Verdun and the Somme had been much more demanding on German divisions and they had to be relieved after only a few days in the front line, lasting about 14 days on the Somme. A larger number of divisions might reduce the strain on the and realise a surplus for offensives on other fronts. Hindenburg and Ludendorff ordered the creation of another 22 divisions, to reach 179 divisions by early 1917.
