Cordula Buss is a Senior Finance & Transformation Advisor and the owner of Plan A2C in Hamburg. She helps CFOs, heads of controlling, and program leads in complex organizations establish robust management logic and governance structures within SAP and finance transformation programs—so that decisions can be made, not just reports generated.

That is how The Steering Audit came to be
Over twenty years of experience with these programs have shown me one thing: the ability to steer a program rarely fails because of the data—but rather because of governance, KPI logic, and decision-making structures. This pattern has evolved into a process: The Steering Audit. A structural assessment of the steerability of your transformation program—in four weeks, at a fixed price.
What I do — and how I work
Over 20 years. Six industries. Always the same diagnosis.
The data was available. The systems were up and running. And yet the steering committee was unable to make any decisions—because the control logic was missing.
That’s exactly what I do: I develop the governance and decision-making structures that make a transformation program manageable in the first place—and, as Program Lead, I oversee their implementation. Not as an SAP specialist who generates reports, but as someone who defines how management should work, designs the right structures, and ensures that Finance, IT, and the business are all on the same page.
The result: steering committees with the authority to make decisions. Forecasts based on a clear logic. Finance as a governance body—not merely a provider of numbers.
