six passages · cognitive shifts, not titles · 18–24 months to develop a successor

Leadership pipeline & C-suite succession

Drotter\'s pipeline isn\'t about job titles — it\'s about cognitive shifts. Two people both holding “Director” can be in different passages depending on whether they\'ve made the mental shift the next altitude requires. The exam reliably tests passage identification by behavior, not headcount.

Drotter\'s six passages

each one a different mental model

01

Self Others

letting go of doing the work

02

Others Managers

managing managers and the function

03

Managers Function

strategic perspective on the function

04

Function Business

P&L ownership · cross-functional

05

Business Group

capital allocation across businesses

06

Group Enterprise

board governance · long-horizon strategy

The most common failure mode: someone\'s promoted to the next role and continues operating in the previous passage. They were good at the old work; they weren\'t shown the new work. Senior HR identifies which passage the person hasn\'t crossed and builds the development plan from there.

replacement planning

One name per role

“If the SVP leaves, X takes the seat.” Brittle — doesn\'t prepare the org if X isn\'t ready, isn\'t willing, or also leaves. The wrong answer when the exam asks about strategic succession.

succession planning

A pool, not a name

For each critical role, three buckets: Ready Now (≤ 12 months), Ready 1–2, Ready 3–5. Calibrated against 9-box, audited for diversity. Develops the pool through stretch assignments and external exposure.

a wrong answer the exam plants

External C-suite hires are not inherently a failure of succession.

Industry shift, major transformation, no internal match — sometimes external is the right answer. The exam may treat “always promote internally” as a wrong answer. Senior HR\'s job is honest assessment, not internal-promotion-by-default.

Exam Traps

Drotter's Pipeline is about cognitive shifts, NOT job titles

Two managers of managers can be in different passages depending on whether they have made the shift away from operational work. The exam tests passage identification by behavior, not title.

9-box at C-suite is more nuanced than at the manager level

Top performers are not automatically successor-ready. The exam may offer "high performer" as a successor answer when "high performer + high potential + ready now" is the correct standard.

Succession planning is NOT replacement planning

Succession develops a pool. Replacement names a single backup. The exam tests whether candidates know the difference.

External hires for C-suite are NOT inherently a failure

Sometimes the right answer is external (industry shift, transformation requirement, no internal match). The exam may treat blanket "always promote internally" as wrong.

High performance ≠ successor-ready

A high-performing executive is not automatically successor-ready. Performance + potential + passage-readiness is the standard.

Identify the missing passage

When the exam describes a leader stuck after promotion, identify which Drotter passage they have not crossed. The development plan flows from the passage, not the function.

1
Identify the runners at each leg

Map the C-suite and the next two layers below using Drotter's passages.

2
Check whether each runner has run THIS leg

Performance in the current passage matters, not just performance in the previous one.

3
Identify the next runners at each exchange

Use the 9-box at executive level. Map Ready Now, Ready 1-2, Ready 3-5.

4
Train the next runners now

Stretch assignments, executive coaching, board exposure, external education. The race does not pause for development.

5
Test the handoffs

Run a tabletop simulation of unexpected vacancies. If three batons drop simultaneously, the bench has gaps.

Picture the relay race. Where is each runner. Who is warming up. The right answer is whichever option strengthens the next runner BEFORE the handoff.
