Calculating the global optimum AI: How CFOs derive the best portfolio decision from 50 projects out of 1,125 quadrillion combinations

In board meetings, it often sounds simple: "We have 50 projects, let's prioritize the best 10." In reality, this is a dangerous simplification. Because as soon as projects are not evaluated in isolation, but compete with each other in a portfolio (budget, resources, time, capacities, dependencies, risks, political or operational constraints), a decision-making space is created that humans and Excel can no longer master cleanly.

This is exactly where the topic of global optimum calculation AI begins: not "which project is good?", but which project combination delivers the highest overall benefit under real restrictions. And not locally (a little better), but globally: the best combination in the entire space of all possibilities.

Why "50 projects" are not 50 decisions

If there are 50 projects to choose from and each project can basically be "yes" or "no" (simplified: to include or not to include), then there are not 50 possible decisions, but:

2⁵⁰ possible project portfolios

That is 1,125,899,906,842,624 combinations, i.e. around 1,125 quadrillion. In practice, it is even more multidimensional, because projects are not only binary (full/not at all), but also contain budgets, phases, capacities, risk corridors, dependencies and minimum/maximum values. But even in simple binary logic, the order of magnitude is already clear: the space is no longer "testable" for classic committee logic.

The result is not that decision-makers are "bad". The result is that the system forces them to guess: You only see a tiny section of combinations, discuss a few variants, tweak them - and then call that "best possible". CFOs know this: This is often local optimization under time pressure, not a real global solution.

The executive problem: suboptimality is the norm

In portfolio management, the biggest losses in value are rarely spectacular. They are quiet. One project too many, one project at the wrong time, a resource at a bottleneck, a dependency underestimated, a risk incorrectly priced. The result is not that "everything is wrong", but that the portfolio is systematically suboptimal.

The CFO sees the consequences in typical symptoms:

• CapEx is tied up without the expected effect materializing.
• Resource bottlenecks destroy good projects in terms of time.
• Programs collide: IT, processes, compliance, ESG, sales - all at the same time.
• Dependencies are recognized too late (or financed too late).
• Risk accumulation results from "too many of the same bets" in the portfolio.

In CFO-speak: this is not just a planning problem, it's a math problem. And that is precisely why the core approach is: calculate global optimum AI - not as a buzzword, but as a concrete ability to evaluate the entire decision space and identify the best combination.

Why Excel and classic PPM tools fail systemically at this point

Excel is excellent for transparent models. But Excel is not built to search through 1,125 quadrillion combinations. Even if you "only" calculate a simple evaluation for each combination, the sheer number of possibilities is the problem. The decision space grows exponentially. This means that each additional project option doubles the space.

In turn, many PPM tools work with scoring, weighting, ranking lists, traffic lights and portfolio bubbles. This is helpful for communication - but it is no guarantee of the global optimum. It remains a heuristic: an intelligent approximation that often misses the mark in complex spaces because interactions and constraints cancel out the ranking list.

To put it bluntly: What is not calculated is guessed. The difference is: With 5 projects, you can guess without much damage. With 50 projects, guessing is expensive.

The 50-project example: this is how the CFO reality is created

Let's take a typical company (or municipality) with 50 project initiatives. The categories could be:

• IT modernization and platforms
• Cybersecurity and resilience
• Operational excellence / lean / automation
• Site and infrastructure measures
• ESG, energy, CO2 reduction
• New products, innovation, market expansion
• Compliance, audit findings, regulatory programs
• Personnel, qualification, organizational development

Now comes the CFO perspective: the budget is limited, capacities are limited and time is limited. There are also tough constraints:

• CapEx cap per year / quarter
• Opex follow-up costs (run costs) as a restriction
• Resources (IT architects, project managers, external partners) as a bottleneck
• Dependencies (project B only goes ahead after A, C needs B, etc.)
• Risk limits (maximum parallel critical deployments)
• Minimum programs (regulatory requirements must be met)

In this reality, it is absolutely plausible that the "best" individual project will not end up in the best portfolio because it eats up resources, blocks dependencies or causes follow-up costs. Conversely, a mediocre individual project can become very valuable in the portfolio because it solves bottlenecks or accelerates other projects.

This is precisely why global optimum calculation AI is essentially a portfolio capability: AI not only evaluates projects, but also combinations under restrictions.

StratePlan: From gut feeling to predictable portfolio decisions

The key management question is: How do I get from the exponential space to a reliable decision without losing weeks or months in committees - and without silently guessing?

The answer is a solution that explicitly addresses the space: it must mathematically represent the entire decision space, map restrictions, define benefit functions, calculate trade-offs and determine the best combination.

This is the idea behind StratePlan: calculating the global optimum AI here means that the system does not suggest "top 10 projects", but rather the optimum project combination that generates the maximum overall benefit under your restrictions.

StratePlan calculates the entire decision spaceand finds the global optimum:

The one project combination that generates the maximum overall benefit.

The size comparison: Why 1,125 quadrillions are not "intuitive" for people

People can understand large numbers, but they cannot feel them intuitively. This is precisely why the size comparison is helpful: it makes the discrepancy between what we perceive as "large" and what a 2^N space actually means visible.

The important executive conclusion from this: If your decision space is orders of magnitude larger than anything humans can survey, then "discussion" alone is no longer an optimization method. Discussion is governance. Optimization is mathematics.

The management consequence: Without calculation, a false sense of security is created

Many organizations create a false sense of security by consolidating processes: more meetings, more templates, more scorecards, more traffic lights. This makes decisions easier to communicate. But it doesn't automatically make them optimal.

If you have 1,125 quadrillion combinations, then every manually discussed variant is statistically a tiny dot in a gigantic space. Even if you were to check 1,000 variants (which practically nobody does), that would still be "nothing" in relation to the total space.

This is precisely why the leitmotif is so harsh, but so true:

What is not calculated is guessed at.

What "global optimal computing AI" actually means

The term is often used in an inflationary way. In the executive context, it should mean three clear characteristics:

1. Overall space-oriented: The solution considers the space of all project combinations (not just ranked lists of individual projects).
2. Restrictive: Budget, resources, dependencies, minimum requirements, risk limits are mapped as hard or soft constraints.
3. Optimum-focused: The result is a portfolio combination that maximizes the defined overall benefit (e.g. impact index, NPV, IRR, service level, compliance fulfillment, impact).

Important: "Global" does not mean that targets are absolutely objective. Targets are set by management. But within the defined targets and restrictions, the system can calculate the best solution - and this makes the decision transparent: you can see what the best combination is, and you can also see what it will cost if policy or management deviate from it.

Example setup: 50 projects, CFO-relevant targets

A practicable portfolio model (also as a basis for StratePlan) typically contains the following dimensions:

• Impact: sales contribution, cost reduction, quality improvement, risk reduction, service level, strategic fit
• Costs: CapEx, Opex, follow-up costs, overhead
• Capacity: FTE requirements, critical roles, external partners, delivery capability
• Time: launch window, dependencies, sequencing, time-to-value
• Risk: implementation risk, technology risk, regulatory risk

These building blocks can be used to derive a benefit function that is suitable for CFOs and CEOs: comprehensible, but not academically overloaded. Comparability is crucial: projects are brought into a consistent system so that combinations can be evaluated at all.

The central CFO question: What does a deviation from the optimum cost?

This is one of the biggest practical advantages: as soon as you know the global optimum (in the defined model), every deviation becomes quantifiable. You can say:

• "If we add project X, we lose Y in total benefit because capacities are blocked."
• "If we postpone project Z, we gain budget in the short term, but lose time-to-value."
• "If we take on a politically desirable project, we see the loss of opportunity transparently."

This is how governance grows up: not "my project versus your project", but a transparent trade-off in the portfolio.

Table: Classic portfolio approach vs. global optimum calculate AI

Dimension	Classic approach (scoring/ranking/excel)	Calculate global optimum AI (portfolio optimization)
Unit of decision	Individual project (top lists, rankings)	Project combination (portfolio as an overall system)
Dealing with 2N space	Reduction through discussion, heuristics, templates	Mathematical search of the decision space
Restrictions	Often "soft" (traffic lights, manual exceptions)	Explicit (budget, capacity, dependencies, minimum requirements)
Interactions	Partially considered, mostly qualitative	Systematic in the model (synergies, blockers, sequences)
Result	"Best possible" list according to human process	A calculated best project combination (optimum in the model)
Deviations	Difficult to quantify ("gut feeling", politics, compromise)	Costs of deviation become visible (loss of opportunity)
Transparency	High in communication, limited in mathematical depth	High in decision-making: Conflicting objectives are calculated and visible

Why this means a strategic shift for the CEO/CFO

If you accept portfolio decisions as a 2^N problem, the claim changes:

• From "we prioritize" to "we optimize"
• From "we find compromises" to "we quantify trade-offs"
• From "we decide in committees" to " we decide on the basis of calculated options"

This is not a replacement for governance. It is an upgrade of the decision-making basis. Management remains responsible for goals, policies and priorities. But it no longer makes these decisions blindly in an invisible space, but with a view to the optimum and the costs of each deviation.

The 50-project reality: typical questions that can only be answered properly through calculation

In a 50-project portfolio, questions arise that traditional methods can only answer incompletely:

• Which combination maximizes impact per euro when opex follow-up costs are limited?
• Which projects must be startedtogether to create synergies?
• Which projects are "kill switches" because they create bottlenecks?
• What does the optimum look like if the budget changes by ±10%?
• How robust is the portfolio against risks and delays?

These are CFO questions. And this is precisely where Global Optimize AI makes the difference: not just a decision, but a decision-making landscape with sensitivities, trade-offs and robust alternatives.

Pragmatic implementation: what do you need to make the space predictable?

From an executive perspective, the important thing is that you don't need a perfect academic model. You need a sufficiently good, consistent model that improves decisions. Typically enough:

• A standardized project sheet (costs, benefits, capacity, risk, timing)
• Defined restrictions (budget cap, capacity limits, must-do projects)
• A benefit model (e.g. impact index or financial key figure + strategic weighting)
• Explicit dependencies (A before B, B needs C, etc.)

This makes the space formal. And as soon as it is formal, it can be optimized. The biggest step is not technology, but discipline: make projects comparable, define restrictions honestly, prioritize goals clearly.

Executive takeaway: Why "Calculating global optimum AI" is a governance tool

Many see AI as a technology. In this context, AI is above all a governance tool: it makes visible what was previously invisible. And it enables a decision-making culture based on transparency:

• The optimum is known (in the defined model).
• Alternative portfolios are comparable.
• Deviations are quantifiable.

This makes the discussion in the committee better: not more emotional, but more precise. No longer "we believe", but "we see".

FAQ: Calculating the global optimum AI

1) Isn't "global optimum" illusory because benefit is subjective?

The aim is not to eliminate subjective goals, but to make them explicit. As soon as goals (e.g. impact, risk, time) are defined as a model, the AI can calculate the best portfolio within this framework. This does not increase subjectivity, but makes it more transparent.

2) Why are prioritization and scoring not enough?

Because scoring usually evaluates individual projects. However, portfolios fail due to interactions, bottlenecks and dependencies. The best individual project is not automatically part of the best portfolio. Calculate global optimum AI evaluates combinations, not just rankings.

3) Do I have to have perfect data for this?

No. You need consistent, plausible data and clear restrictions. In practice, a "97-99%" model already provides great added value because it structures the space and makes better combinations visible than any manual variant.

4) What is the greatest practical benefit for CFOs?

Two things: (1) the best project combination under real constraints and (2) the cost of each deviation. This makes portfolio management measurable and defensible - both internally and externally.

5) What happens if the board does not want to implement the optimum?

Then that is completely legitimate. The difference is that you can see transparently what this deviation costs (loss of opportunity) and which alternatives are close to the optimum. Governance thus becomes more conscious.

6) Is this only relevant for corporations?

No. Especially organizations with limited budgets and many competing measures benefit greatly - including public budgets. A 50-project portfolio is typical in both worlds, and the 2^N space is identical.

Conclusion: From the project debate to portfolio math

If you have 50 projects, then you don't have "a lot of work". You have a mathematical system with 1,125 quadrillion possible combinations. If you don't calculate this space, you are inevitably making decisions in an invisible space - and calling the result the "best solution", even though it is almost certainly suboptimal from a statistical point of view.

Global optimal computing AI is therefore not a fashion. It is the logical response to exponential complexity. For CFOs, this means better capital allocation, lower bottleneck costs, more robust programs - and a basis for decision-making that is not based on gut feeling, but on calculated transparency.
