Field cases
Anonymized real cases from the author's experience. Names, companies, and identifying details are removed or generalized. The first two are a matched pair. The three that follow are shorter supporting cases.
Case 1: Build the bench before the seats become empty
Situation. A global financial-services company had an extraordinarily experienced, extraordinarily tenured senior team. Within 18 to 24 months, more than half of several executive and next-level seats were expected to open through retirement or transition.
The ordinary response. Put two names under every critical box and wait.
What the company did instead. It treated succession as a development system, not a replacement list. It identified high performers and gave them real work across business units and functions: commercial leadership, customer service, finance, operations, risk, legal, people, technology, partner management. It stopped treating commercial and support talent as separate populations, and gave everyone a shared question: how does your work contribute to the outcome the customer and the company are trying to achieve? That common language widened the succession pool and lowered the walls between functions.
One leader showed what the system could produce. Recruited from a competitor, he had moved for exposure, not title. His career ran diagonally across commercial and operational domains. He learned how risk, finance, sales, operations, customers, and partners each thought, and how a decision in one place created consequences in another. Breadth did not make him shallow. It gave him situational fluency: he saw more of the system, judged better, decided faster, and delivered results.
Why he was a real successor, not a popular one. Results made him visible, but four other signals made him ready:
| Signal | Evidence |
|---|---|
| Learning speed | Repeatedly productive in unfamiliar businesses and functions |
| Aspiration | Chose assignments that built capability, not just title |
| Operating altitude | Moved from "how does my function succeed?" to "how does the company create value across the customer journey?" |
| Multiplier | Became an advocate and sponsor for developing the next leaders the same way |
What happened. In the first year of broad adoption, growth roughly doubled and margins expanded sharply. The leadership program was not the only cause, but it supported the operating change behind it: leaders understood the enterprise, had wider networks, and aligned around the customer. The company then absorbed leadership transitions, rapid digitization, new competitors, tighter regulation, and a global pandemic while holding its operating performance.
The proof. Years later, two of the most tenured senior leaders in the company's largest region retired at the same time, each with roughly four decades in the industry. He was appointed interim general manager. The plan did not create him when the vacancy appeared. It revealed that the work to make him ready had already been done.
Lesson. The best proof of bench strength is not that someone was labeled ready. It is that when a critical leader leaves, someone steps into the work without the organization losing judgment, relationships, momentum, or customer trust.
Case 2: When the proven external leader did not transfer
Situation. A hypergrowth software company wanted to strengthen its enterprise business. The external candidate looked impossible to beat: decades at a very large, mature enterprise company, rising to lead a global sales organization of thousands serving the world's largest customers, with deep executive relationships. The logic was compelling: who better to teach a young company to sell to the largest enterprises?
The context that changed. His previous company was large, stable, and relationship-driven. His leadership model fit it: hire capable people, give them room, hold them to outcomes, do not over-manage experienced leaders. The new company was growing at extraordinary speed, reorganizing almost continuously, and ran an unusually explicit management system of alignment, priorities, obstacles, and frequent inspection.
Both cultures valued empowerment. They differed in how it worked. In the mature company, autonomy lived inside stable structures. In the hypergrowth company, autonomy depended on tight alignment, shared operating mechanisms, fast feedback, and constant inspection. His instinct to give leaders room, a strength before, became a liability. Teams needed synchronization, not latitude.
What happened. He lasted less than two years. He went on to senior operating and president-level roles at other software companies, which is what makes the case useful: this was a mismatch of operating systems, not a judgment on the executive.
What the process missed. It had strong evidence that he had led a massive organization. It lacked evidence of transferability: what made him successful there, and would those behaviors produce the same results here?
Lesson. Past performance is evidence of capability in a context. When the plan calls for an outside hire, raise the evidence standard: comparable work, operating-context fit, adaptability, and multiplier fit. The most dangerous succession mistakes are not obviously bad candidates. They are outstanding candidates evaluated against the wrong evidence.
The pair
| Built from inside | Bought from outside | |
|---|---|---|
| Sequence | Develop breadth before the vacancy, observe adaptability across contexts, accumulate evidence of readiness, successor steps in | Vacancy or strategic need, extraordinary résumé, transferability inferred from prior scale, mismatch found after appointment |
| Evidence of readiness | Observed in this company's system over years | Inferred from another company's system |
| Outcome | Seamless interim leadership through a double retirement | Exit in under two years |
Succession asks who can do the next job. Bench strength proves it before you need them. A résumé only proves what someone did in the last system.
Supporting cases
The successor nobody planned a path for. A seller labeled unmotivated was found to be underchallenged. With the right mentor he finished near 200% of quota and earned the top-performer award three years running. He wanted to advance. No one named his next challenge, and he left for a competitor. Rule: flag top performers outgrowing their roles every quarter, and name the next challenge or accept that the market will.
The capable practitioner who was not a successor. An exceptional enablement leader had every ability the next stage needed except the wish to develop it. Rule: score aspiration separately from capability. A capable person who has not chosen the next stage is not a successor for it.
The sponsored internal candidate. Favored by a senior leader, he claimed never to have failed. The evaluator recommended against him and was overruled. The appointment ended in termination within a year. Rule: run the sponsorship check in every talent review, and record any override with the risks to watch.
