Rivals are praised, rewarded, and eased into deep expertise in a narrow area expected to become obsolete, so they feel indispensable now and turn irrelevant later.
An example
At a structural engineering firm, two principals were both positioning to run the firm. One of them spotted a talented young engineer who could become a rival in a decade and began booking her onto every project that used the firm's legacy analysis software, a package leadership had already discussed retiring. He praised her in principals' meetings as the person who knew the tool best, arranged a lead-analyst title for it, and kept her off the rotation onto the new design-platform pilot because her projects could not spare her. Her question about the pilot got the answer that generalists were easy to find and real experts were not. Three years later the firm switched platforms, and her specialty was gone.
Why it works
Specializing looks better because the niche brings titles, praise, and go-to-expert status, and becoming indispensable feels like winning. It looks easier because the path is cleared: scheduling, territory, and tools all arrive without friction. Breadth looks worse, recast as dilettantism or a lack of conviction. Nothing makes the alternative look costly, because that would alert the target; the trap depends on them feeling they are progressing until the niche disappears. It needs foresight the target lacks, genuine short-term prestige in the niche, and a target who responds to expert status.
The thinking behind it
Oliver E. Williamson The Economic Institutions of Capitalism (1985) explains that investments specialized to one relationship lose much of their value outside it, leaving the investor dependent. Deep expertise in software a firm plans to retire is such an investment, and it loses value twice: outside the firm and, soon, inside it. Building one transferable skill a year and asking for rotations keeps the investment less specific.
Hal R. Arkes The Psychology of Sunk Cost (1985), by Hal Arkes and Catherine Blumer, describes a greater tendency to continue an endeavor once time and effort have been invested, and found that people who had already invested rated a project's chance of success higher. A specialist with years in a niche tends to rate the niche's future more highly than it deserves. Mentors outside the niche, with nothing invested, give the more honest read.
Warning signs
Booked onto legacy work again and again, one person is shielded from rotation because the work supposedly cannot spare them. They are praised as the go-to expert and given a title for the niche. Breadth and lateral moves are dismissed as dilettantism in conversations with them. The niche rests on a system or rule that leadership has discussed retiring.
How to defend yourself
Form your own view of where the technology and the market are heading, and check it with people who have no stake in your current work.
- Keep mentors outside the influence of whoever is steering your assignments, and ask what they would do in your place.
- Ask for rotations even while the niche is rewarding, and put the request in writing.
- Find out whether the system or rule behind your niche is on any retirement or replacement plan.
- Build one adjacent skill each year that transfers outside the niche.
Praise and protection that come from the same person who controls your assignments deserve a second look.
How a leader shuts it down
Build rotations into every high-potential track, and do not let a manager block them on the grounds that a project cannot spare someone. Review who is staffed on systems scheduled for retirement and what their next role will be. Reward breadth in promotion criteria alongside depth.
