The Competency Trap¶
Definition¶
A competency trap is what happens when you keep doing what you already do well, get even better at it, and so keep doing more of it — while the environment's requirements move on without you. The habits and mind-sets that produced past success persist long after they've stopped fitting the job, because they are reinforced by comfort, visible results, and the false assumption that past wins predict future ones.
In the Book¶
Chapter 2 develops this through two cases. Sophie, a supply-chain rising star, delivered impeccably on her KPIs but was blindsided when a reorganization of her function was discussed without her — she had no relationships above her level and no outside view of how supply-chain management was shifting industry-wide. Her ideas were dismissed as parochial until she forced herself into cross-functional and external conversations, eventually concluding a "180-degree turn" in strategy was needed that made most of her prior work irrelevant. Jeff, a general manager built entirely on sales-turnaround wins in three successive postings, kept running the same playbook in a larger, more complex assignment — micromanaging (Marshall Goldsmith's "adding too much value"), ignoring corporate initiatives, and alienating his data-driven marketing chief — and stalled out despite delivering results, because his bosses were now evaluating a different, broader capability. Ibarra frames both as "doing the wrong things well": competent execution of an increasingly obsolete definition of the job.
Why It Matters¶
The trap explains why strong performers get stuck rather than promoted: the same discipline and specialization that built their track record becomes the thing blocking their next step. It generalizes beyond individual careers to any system — a product line, a company, a skill — that keeps optimizing a formula validated by past success instead of noticing that the criteria for success have moved. Naming it lets you ask a sharper question than "am I doing well at my job?" — namely, "is my job still the job that needs doing?"
