Succession Planning
Succession Planning
What is succession planning?
- Identify and develop successors for key roles in advance
- Guard against sudden vacancies
- Talent pipeline management
Adopting succession planning moves HR decisions earlier. A hiring problem, finding someone within three months of a vacancy, becomes a development problem: choosing and growing candidates while the incumbent is still in the seat. The work shifts from filling empty seats to managing candidate readiness. That is why the first deliverable in a well-run organization is not a new org chart but a candidate list for each role, with a readiness timeline for each candidate.
Candidates are usually sorted into three tiers: ready-now candidates who could step in immediately, candidates who need one to two years of development, and long-term candidates who need three or more years. Aim for two to three candidates per key role, and track coverage, the share of roles with a candidate in place, as a management metric. It is easy to confuse with replacement planning, but the two are distinct. Replacement planning is closer to an emergency contact list that records 'if that person is out today, who signs off in their place?', while succession planning comes with a multi-year development schedule attached. It also needs to be distinguished from a high-performer pool. The people performing well now and the people who can handle the next level up are two different sets.
The most common failure in practice is building a list without attaching development assignments. If a candidate's name has sat in a spreadsheet for two years and their scope of work hasn't changed at all, the 'ready candidate' exists only on paper when a real vacancy hits. Naming just one person per role is also risky: the moment that person leaves, the whole plan is back to a blank page. Whether to tell candidates depends on company culture, but if you do, make clear that it is an opportunity, not a guaranteed promotion. Unless you also set criteria for how those who are not selected will be treated, publishing the list can speed up the departure of key talent.

Consider a hypothetical case: Company A, an automotive precision-parts maker with 320 employees and annual revenue of KRW 118 billion (≈ US$88,283,700). Six of its nine key roles were held by people aged 55 or older, and two of them were due to retire within three years. What prompted adoption was an earlier incident: after the purchasing manager left for a competitor, raw-material price negotiations stalled for four months and costs jumped 3 percentage points.
- When the HR head asked at an executive workshop, 'If this seat were empty tomorrow, who would sign off?', only 3 of the 9 key roles had a candidate name ready right away.
- The CEO and 5 division heads held a two-day talent review meeting and placed 47 managers and above into three boxes: ready now, within 2 years, 3+ years. Only 4 candidates were ready now.
- The 2 successor candidates for the quality executive were given a six-month assignment: take full ownership of an overseas client claims-handling project. The current executive was asked to log coaching notes once a month.
- Each quarter, the CEO personally checked the readiness of 12 candidates. In the process, 2 said, 'I want to stay a field expert,' so they were removed from the list and 3 other candidates were added.
- Two years later, when the Head of Production Engineering retired, an internal candidate took over within two weeks and no line was stopped. Coverage of key roles rose from 33% to 89%, and turnover among key talent fell from 11% to 6%.
