The organisation and mission of OKW/Chi changed significantly in the summer of 1944, principally centered on the attempted assassination of Hitler. Whereas OKW/Chi had supposed jurisdiction over all cipher agencies within the Armed Forces, after Summer 1944, Director Wilhelm Fenner persuaded Generalleutnant Albert Praun, General of the Communications Troops of the need to centralise all results and efforts within OKW/Chi, and to issue an order to that effect. After the order, OKW/Chi no longer acted like a service agency, but instead set policy and became the primary jurisdiction for all work done on cipher development, message decryption and associated machinery design and construction. The organisation changed significantly, with new commanding officers, more focus for Chi IV function and increased staffing levels.
