The German Basic Law builds federal government on three principles that pull in different directions. Under Article 65, the Federal Chancellor determines the general guidelines of policy and bears responsibility for them. Within those guidelines, each federal minister runs their portfolio independently and on their own responsibility. And where ministers disagree, the cabinet decides as a collective body. The Federal Chancellery is the institution that turns this constitutional triangle into a working routine.
Its Head is responsible for the organisation that supports the Chancellor day to day. In practice this means following the work of every federal ministry through dedicated "mirror" units, preparing the weekly cabinet meeting and the state secretaries' meetings that precede it, and making sure that draft legislation, regulations and strategic decisions have been agreed between the departments before they reach the cabinet table.
The Chancellery is also the government's interface. It manages the flow of information between the Chancellor and the ministries, keeps contact with the parliamentary groups of the governing coalition in the Bundestag, prepares the meetings between the Chancellor and the heads of government of the sixteen Länder, and traditionally coordinates the federal intelligence services. In a crisis, it is where information from many departments has to be brought together so that the Chancellor and cabinet can decide on a shared picture.
None of this gives the Head of the Chancellery authority over the ministers. The office does not issue instructions to departments, and policy responsibility stays with each minister and, overall, with the Chancellor. Its influence lies in preparation, timing and coordination — which is precisely why the role is so demanding.
