Core rigidity
A core rigidity is a once-valuable capability that has hardened into a barrier to change.
The capabilities that make a firm strong can harden, over time, into the very things that prevent it from changing. A core rigidity is a strength turned into a shackle.
A core rigidity is a capability that was once a source of advantage but has become an obstacle to adaptation and change. The term, coined by Dorothy Leonard-Barton, captures the dark side of core competences: that the deeply embedded strengths defining what a firm does well can also define what it cannot do, or cannot stop doing.
The flip side of competence
A core competence is a capability so well developed and embedded that it gives a firm advantage. The trouble is that the very depth and entrenchment that make a competence powerful also make it rigid. The skills, values, systems, and routines built up around a core competence become so established that they resist change, filter out information that does not fit, and channel the organisation toward more of the same. When the environment shifts and a different capability is needed, the old core competence does not gracefully step aside; it actively obstructs the new, becoming a core rigidity.
Why strengths resist change
Core rigidities are hard to overcome because they are bound up with identity and success. The competence is what the firm is known for, what its people are skilled at, what its systems are built around, and what has historically been rewarded. Abandoning or even questioning it threatens all of that, so the organisation defends it, often unconsciously. The firm most invested in a core competence is the one most likely to find it has become a rigidity, and the least able to see it.
Holding capability and flexibility together
The challenge the concept poses is that firms need deep capabilities to compete, yet those same deep capabilities risk hardening into rigidities. There is no simple resolution, only the discipline of remaining alert to the possibility that a treasured strength has outlived its usefulness, of nurturing some diversity and exploration alongside the core, and of being willing to renew or relinquish a competence before it becomes a trap. This is much of what dynamic capabilities are meant to provide.
Core rigidity is the warning that accompanies every core competence: that the source of today's advantage can become the source of tomorrow's failure. It explains why deeply capable firms can be so spectacularly unable to adapt, and why the strengths a firm is proudest of deserve the most scrutiny when the world begins to change.
