What aviation knows that most companies don’t: the MR³ method

Mario Rodríguez · October 2026 · 7 min read

No pilot takes off because the plane “feels” fine. Before every flight there is a checklist. In the air, decisions follow instruments, not hunches. There is a flight plan with alternate airports in case conditions change. And when an indicator crosses a limit, an alarm goes off before the problem becomes serious.

I spent many years in airline finance. That is where I learned that this discipline doesn’t belong only in the cockpit. It is exactly what most small and mid-sized companies are missing when it comes to managing their money. The MR³ method grew out of that idea.

The problem: companies flying without instruments

There are more than 36 million small businesses in the United States: 99.9% of all businesses, employing almost half of private-sector workers. Yet only about half of new establishments are still operating five years later. And according to the Federal Reserve, over the past year 77% of small employer firms faced financial challenges from rising costs (goods, services or wages) or tariffs.

Most of these companies don’t have an effort or talent problem. They have an instruments problem. They decide without knowing how many months of cash they have left, without testing what happens if sales drop, and with a budget no one looks at. It is like flying at night without a dashboard.

The MR³ method in three words

1. Measure: the pre-flight check.
It starts with the MR³ Index, a 0–100 score that shows in numbers where the company stands. It evaluates five areas: liquidity (30%), capital structure and debt (25%), governance discipline (20%), operational efficiency (15%) and adaptive capacity (10%). The result is read as a level of risk: low, moderate, elevated or critical. “I think we’re doing fine” is replaced by a number, and that number can be improved.

2. Rebuild: the flight plan with alternates.
With that diagnosis comes a plan: a rules-based budget, debt renegotiation, cost adjustments and 12–24 month models with three scenarios (conservative, base and expansion). This is where one of the method’s key ideas comes in: points of no return. Before committing to a cost that can’t be undone, such as a contract, a hire or an investment, the condition that must be met is defined in advance, for example confirmed revenue rather than expected revenue. If the condition isn’t met, the company doesn’t move forward. That protects cash and margin.

3. Resist: instruments and alarms.
The final phase installs what stays: key indicators, dashboards that update themselves and early warnings with concrete thresholds. The system flags, for example, when free cash covers less than two months of essential outflows, when net financial debt exceeds 4.5 times adjusted EBITDA, when what the operation generates before salaries no longer covers payroll, or when gross margin falls more than 8% against the same quarter a year earlier, two quarters in a row. The alarm goes off before the emergency, not after.

AI as copilot, not pilot

MR³ uses artificial intelligence, with clear rules. AI helps analyze scenarios, review variances and simulate decisions faster. It works within defined uses, a person validates every output, and everything is logged. AI never makes the decision or replaces leadership’s accountability. In aviation, the autopilot flies much of the route, but the pilot stays in command. Here it works the same way.

How it differs from everything else

A company can have an accountant, advisors, software and AI tools, and still not have a system. Here is the difference:

MR³ doesn’t compete with the accountant or the software: it organizes them into one architecture. And it has five traits you won’t find together anywhere else:

1. It comes from aviation discipline, where mistakes are costly and everything is measured.
2. It is measurable from day one, with a 0–100 index that can be recalculated to track progress.
3. It uses thresholds and points of no return, not opinions, to decide when to invest and when to stop.
4. It governs AI instead of just using it.
5. It is designed to stay. Success is measured when the company no longer needs the consultant to make good decisions.

Why it matters for a small business

When a small business stabilizes, it keeps its team, pays its suppliers on time and can invest again. When it closes, the owner is not the only one hit: the impact is felt across the whole chain.

Large corporations have entire departments dedicated to planning, measuring and anticipating risk. Most small businesses don’t. MR³ brings that capability to companies that can’t afford a full finance team. And because it is documented, the team can learn it and keep using it without depending on a single person.

What it has already shown

The principles behind MR³ were proven in demanding environments. At an airline launching operations in Argentina, weekly cash and payment controls helped lift on-time performance from 68% to 95%. At a media and education company hit by the pandemic, more than $400,000 in liabilities was restructured and fixed costs fell 23% in six months. At a foundation running programs in more than 15 countries, budget accuracy rose above 90%. In every case, the systems kept running afterwards.

One question to finish

If you had to land your company in the middle of a storm today, would you have instruments, an alternate plan and alarms in time? If the answer isn’t a clear yes, the first step is to measure.
