In an economic, ecological and geopolitical world marked by growing uncertainty, two concepts emerge as strategic compasses for organizations: robustness and adaptation. Far from being antagonistic, these two notions could well constitute two sides of the same coin: organizational viability in the 21st century.
But can we really be robust and flexible at the same time? Doesn’t an excess of robustness condemn us to sclerosis? And conversely, doesn’t limitless adaptability risk making us lose our bearings? Let’s explore this fertile dialectic.
Robustness: much more than a question of solidity
When we evoke robustness, the image that spontaneously comes to mind is that of the oak tree resisting storms thanks to its massive trunk. Yet this vision does not do justice to the richness of the concept as it is understood today, notably by biologist Olivier Hamant.
A definition inspired by living systems
In biology, robustness refers to a system’s capacity to maintain its short-term stability and long-term viability despite fluctuations. Contrary to what our intuition might suggest, living organisms are not optimized for maximum performance. They are, on the contrary, “suboptimal”: our body temperature, for example, is not the one that maximizes the activity of our enzymes.
This apparent suboptimality is in reality a survival strategy. It creates margins of maneuver that allow the system to remain functional in the face of environmental variations. Living systems thus favor:
Redundancies rather than efficiency at any cost
Diversity rather than extreme specialization
Heterogeneities rather than uniformity
Delays rather than immediate responsiveness
Robustness vs performance: a paradigm shift
Our modern society has made performance its mantra. In companies, we seek to optimize every process, reduce every cost, accelerate every cycle. This quest for maximum efficiency has given rise to just-in-time supply chains, hyper-rationalized organizations, agricultural monocultures.
The problem? These over-optimized systems are extraordinarily fragile. The COVID-19 pandemic reminded us brutally: global logistics chains collapsed at the first grain of sand, health systems optimized for “occupancy rate” failed to absorb the shock, companies without reserves faltered.
As Olivier Hamant points out, to optimize is to make fragile. Every optimization reduces diversity, margins of maneuver, and the system’s capacity for adaptation.
The evolution of robustness through time and cultures
Are our societies more or less robust than before?
This question deserves attention. At first glance, our modern societies seem more robust: we have developed sophisticated infrastructures, insurance systems, crisis management protocols. Yet this apparent robustness hides a systemic vulnerability.
Elinor Ostrom’s work on the commons shows that certain traditional governance systems survived centuries of wars, famines and pandemics. Shared aquifers, irrigated fields, mountain pastures managed collectively. Their secret? A governance architecture that favored redundancy, participation, self-organization and gradual adaptation.
Conversely, our contemporary systems, despite their technical sophistication, often present a fragility due to centralization and over-optimization. A global IT outage can paralyze thousands of companies. A semiconductor supply shortage blocks entire industries.
The cultural dimension of robustness
The conception of robustness varies across cultures. Japanese societies, marked by earthquakes, have developed a culture of preparation and redundancy. Traditional rural communities have cultivated polyculture and mutual aid. Indigenous peoples have maintained diversified, orally transmitted knowledge, creating a form of collective cognitive robustness.
Our modern Western culture, obsessed with efficiency, has progressively eroded these forms of robustness in favor of specialization and optimization that paradoxically make us more vulnerable.
Is robustness a brake or an accelerator of adaptation?
Here lies the heart of our reflection: are robustness and adaptation antagonistic or complementary?
When robustness sclerotizes
An excess of robustness can indeed lead to rigidity. When an organization invests all its energy in anticipation and risk management, it can:
Develop a culture of control that stifles initiative
Create processes so heavy that they slow down all evolution
Consume considerable energy imagining scenarios that may never occur
Lose its capacity to seize emerging opportunities
This is what we observe in certain large bureaucracies: a procedural robustness that killed adaptability. The former USSR offered a striking example of a system that was very resistant but not very resilient, paralyzed by its excessive centralization.
When limitless adaptation exhausts
Conversely, adaptability without counterweight can become pathological:
Constant change exhausts teams and destroys the feeling of stability
The absence of stable reference points prevents the construction of a strong organizational identity
Excessive reactivity leads to treating symptoms without taking the necessary step back
“Everything adaptable” can lead to a loss of coherence and direction
As our research on the Adaptation Coefficient points out, adaptation is not an end in itself. It must serve to maintain or improve performance and well-being, not turn the organization into a weathervane.
Robustness in service of adaptability
What if we reversed the perspective? What if robustness, properly understood, were precisely what enables adaptation?
Suboptimality as a space for adaptation
Living systems teach us that robustness creates the conditions for adaptability. By preserving margins of maneuver, maintaining diversity, avoiding excessive optimization, they give themselves the space needed to explore, experiment, evolve.
A factory operating at 80% of its capacity rather than just-in-time can absorb an urgent order or compensate for a breakdown. A team that has “free” time can innovate, train, anticipate. An organization that maintains a diversity of skills can pivot toward new markets.
Robustness is about creating the conditions so as not to have to adapt in urgency and panic, but to be able to do so deliberately and constructively.
The invariants of an organization that is both robust and adaptable
Our work on adaptable organizations reveals interesting patterns. Collectives that excel in both dimensions share common characteristics:
Stable values but flexible methods: the “why” is robust, the “how” is adaptable
An explicit and living culture that provides a secure framework for experimentation
Clearly defined non-negotiables that create boundaries within which adaptation is free
Regular rituals that maintain cohesion while allowing evolution
An architecture of disagreement that institutionalizes questioning without destroying trust
This approach echoes distributed governance: by distributing decision-making power, we simultaneously create robustness (if one link weakens, the system continues) and adaptability (decisions are made closest to the ground).
Balancing robustness and adaptation: a question of dosage
The key, then, is not to choose between robustness and adaptation, but to find the right balance between the two. This balance is not static; it varies according to:
The context and sector of activity
A nuclear power plant must favor procedural robustness. A tech startup must bet on adaptability. But even in these extreme cases, the other dimension remains necessary: the power plant must be able to adapt to new safety standards, the startup must have robust values that guide its evolution.
The development phase
A young organization needs adaptability to find its market. A mature organization must maintain its robustness while remaining able to evolve. As our reflections on agile methods illustrate, the balance between stability and agility must be constantly reassessed.
The nature of the change
Faced with a predictable and gradual change (regulatory evolution, announced technological transition), robustness through anticipation is appropriate. Faced with an unpredictable and brutal change (health crisis, market disruption), adaptability becomes vital.
Adaptation as a “third way”: neither resistance nor submission
In our article on adaptation between resistance and submission, we explored the idea that adapting is neither passively yielding to constraints, nor digging in against change.
Robustness enriches this reflection: it gives us the strength not to suffer. A robust system is not at the mercy of every fluctuation. It can choose when and how to adapt, rather than being forced to do so in urgency.
It is precisely this capacity for deliberate choice that distinguishes suffered adaptation from chosen adaptation. Robustness creates the space for this deliberation.
Toward organizations that are both stable and flexible
How, concretely, can we simultaneously develop robustness and adaptability in our organizations?
Cultivating cognitive robustness
Diversify sources of knowledge rather than betting everything on a single type of expertise
Institutionalize pauses and time for reflection as advocated by the suboptimality of living systems
Maintain “dormant” knowledge that can be reactivated when needed
Develop nonviolent communication that allows disagreements to be expressed without fracturing the collective
Building structural robustness
Create strategic redundancies (not everywhere, but at critical points)
Avoid excessive centralization by developing shared governance models
Maintain financial margins rather than reinvesting everything immediately
Preserve unused production capacities to absorb peaks or crises
Developing conscious adaptability
Clearly define what is negotiable and what is not
Practice co-development to learn collectively from complex situations
Measure your Adaptation Coefficient to identify dimensions to strengthen
Create fast feedback loops while maintaining a long-term vision
The wisdom of “and” rather than the tyranny of “or”
The tension between robustness and adaptation is not a problem to be solved, but a paradox to be managed. The most enduring organizations are neither the most robust nor the most adaptable, but those that know how to navigate intelligently between these two poles.
Like the reed and the oak in the fable, it is not about choosing a side. It is about simultaneously developing:
The depth of roots that anchor us (robustness)
The flexibility of branches that bend without breaking (adaptation)
In an increasingly fluctuating world, this wisdom of “and” becomes vital. It invites us to:
Build robust systems that do not collapse at the first disturbance
Maintain our capacity for adaptation to evolve in the face of profound changes
Create margins of maneuver that give us the luxury of deliberate choice
Cultivate the creative suboptimality that makes adaptation possible
It is by embracing this complexity, by refusing simplistic solutions, that we will build the resilient and human organizations that our era needs. Organizations that do not merely survive crises, but thrive thanks to their capacity to remain stable in their values and flexible in their methods.
