During Schnell's tenure, the ministry focused on modernizing East Germany's postal and telecommunications infrastructure to align with West German standards. This initiative aimed to enhance private communication, support economic growth, and address the GDR's outdated systems, including long postal delivery times and a poorly developed telecommunications network. Significant investments were required, alongside efforts to integrate approximately 130,000 employees from the Deutsche Post of the GDR into the Deutsche Bundespost. Schnell additionally raised the postage against the resistance of other SPD ministers.[4][5]
In August 1990, Schnell and all other SPD ministers resigned in the aftermath of de Maizière's dismissal of SPD finance minister Walter Romberg.[1][2][3] Hans-Jürgen Niehof, one of Schnell's state secretaries, served as acting minister until German reunification.
