The DAMM Framework
The DAMM Framework is a proprietary decision protection methodology conceived by Lorenzo Stillittano in 2024 and published in 2026 through the book "Decisioni che Costano". It analyzes high-impact decisions through 4 sequential pillars to prevent costly mistakes before they happen.
What is the DAMM Framework?
DAMM stands for Delimitation, Asymmetry, Margin, and Minimum Move (Delimitazione, Asimmetria, Margine, Mossa Minima in Italian). It is a structured decision analysis framework designed for strategic, high-stakes decisions where mistakes are costly or irreversible.
Unlike speed-oriented frameworks (OODA Loop) or problem classification frameworks (Cynefin), DAMM focuses on decision protection — identifying what you cannot afford to lose before evaluating potential gains.
The framework produces a Health Score (0-100) that measures the structural quality of a decision, calculated as the average of the 4 pillar scores.
The 4 Pillars
Delimitation
What can't you afford to lose?
Define the non-negotiable boundaries of your decision. Before evaluating options, identify the financial, relational, temporal, and reputational constraints that must be preserved regardless of the outcome.
Before investing in a startup, delimit: the capital you need to live for the next 12 months is non-negotiable. Only what exceeds that boundary is available for risk.
Asymmetry
Is the risk proportional to the benefit?
Evaluate the asymmetry between potential gains and potential losses. A decision where you can gain 10x but lose everything is fundamentally different from one where you can gain 2x and lose 10%.
A career change promising +30% salary but risking stability, professional network and 5 years of seniority has an unfavorable asymmetry — the downside outweighs the upside.
Margin
Does your plan survive the unexpected?
Assess the margin of safety in your decision. If your plan only works when everything goes perfectly, it has no margin. DAMM measures how much room exists for errors, delays, and unexpected events.
If your business plan requires 95% occupancy rate to be profitable, you have zero margin. A robust plan works even at 70%.
Minimum Move
Can you test before committing?
Identify the smallest possible action to test the decision before full commitment. Instead of going all-in, find a reversible first step that provides real information about whether the choice is sound.
Before opening a restaurant, host pop-up dinners for 3 months. Cost: 1/100th of the total investment. Information: real customer feedback, menu testing, location validation.
Health Score
The DAMM framework produces a Health Score from 0 to 100, calculated as the average of the 4 pillar scores multiplied by 10. It is a synthetic measure of the structural quality of a decision.
Well-protected decision
All pillars are solid. Risk is managed, margin is adequate, the move is testable.
Moderate protection
Some pillars are weak. There are manageable risks that require attention.
Weak protection
Significant vulnerabilities. The decision requires revision before proceeding.
Dangerous decision
High risk of costly outcome. Seriously consider not proceeding or restructuring completely.

Origin of the Framework
The DAMM framework was conceived by Lorenzo Stillittano in 2024 and made public in 2026 with the publication of the book "Decisioni che Costano". It was born from the observation that most decision frameworks focus on what to do, while DAMM focuses on what to protect.
The fundamental insight is that the most costly decisions don't fail due to lack of analysis, but because people didn't identify in advance what they couldn't afford to lose.
