Why the Chancellor only knows the true cost of his decisions when the entire portfolio space is calculated

Executive Summary

Political decisions at federal level today are effectively portfolio decisions. Every decision - be it a budget law, Investment program, funding initiative or reform - does not stand in isolation, but competes for limited resources: budget, time, political attention, administrative capacity and social acceptance, political attention, administrative capacity and social acceptance.

The central problem:
The federal government knows the costs of individual measures, but not the costs of its decisions.

This is because the actual costs do not arise ex post in the budget, but ex ante in the decision-making area - through what isnot implemented because something else was prioritized.

1. Costs are not incurred in the budget, but in the decision-making area

In traditional government processes, projects are evaluated individually:

• Costs per measure
• expected effects
• political feasibility

What is missing is the systematic calculation of alternatives. Every decision generates opportunity costs:

• Which projects are dropped?
• Which combination would have achieved more impact with the same budget?
• Which interactions reinforce or neutralize each other?

Without this perspective, every decision remains economically incomplete.

2. The Federal Chancellor decides on portfolios - not on individual projects

In fact, the Federal Chancellor always decides on

• Investment portfolios (infrastructure, energy, digitalization)
• Reform portfolios (social affairs, education, labor market)
• Crisis portfolios (defense, migration, climate adaptation)

These portfolios consist of dozens to hundreds of measures that:

• are interdependent,
• compete for the same budget,
• reinforce or weaken each other.

From a certain level of complexity, it is clear:
Intuition, scenarios and cabinet votes are no longer enough.

3. Why scenario policy inevitably produces the wrong decisions

Political decision-making today works predominantly with:

• 3-5 scenarios
• linear impact assumptions
• isolated cost-benefit calculations

The problem is mathematically clear:
The real decision space grows exponentially.
With just 20 projects, there are over a million possible combinations.
With 50 projects, there are over a trillion.

No chancellor's office, no ministry and no council of experts can think of this space - let alone compare it.

4. The chancellor's true responsibility: the cost of not making a decision

Political responsibility does not just mean:

"What does this measure cost?"

But above all:

"What better decision did we not make?"

These costs are:

• invisible,
• not budget-effective,
• difficult to communicate politically,

but economically real.
They determine growth, competitiveness and social stability for decades.

5. Without a complete portfolio calculation, there is no cost transparency

Transparency is not created by more reports, but by

• complete mapping of all permissible project combinations,
• explicit consideration of conflicting objectives,
• mathematical optimization under real constraints.

Only when the entire portfolio space is calculated can the federal government:

• know the actual costs of its prioritizations,
• Measure impact maximization objectively,
• Justify its decisions to parliament and the public.

Everything else is informed intuition - but not rational governance.

6. Decision-making competence in the 21st century is calculation competence

The question is not whether political leadership has become more complex.
It already is.

The real question is:

Does the federal government want to continue making decisions as it did in the 20th century -
or start calculating decisions in the 21st century?

Without calculating the full decision and portfolio space, the Federal Chancellor does not know the costs of his decisions.
He only knows their justification.

And this is precisely the difference between administration and leadership.

Finally calculate the full costs of political decisions
