How is skills-based succession planning different from a nine-box grid?

A nine-box rates performance and potential as two opinions per person. Skills-based readiness compares assessed levels to a role's required levels, skill by skill, so it states what is missing and what would close it.

Which roles need a succession plan?

Roles where a vacancy stops work, breaks a compliance requirement, or takes knowledge nobody else holds. Start there. The list is usually a few dozen roles, not every title with direct reports.

How many successors should a critical role have?

At least two people who are ready now or ready soon. One successor is a single point of failure with a name attached.

Can someone be a successor for a role in a different department?

Yes, if their assessed skills match the profile. Comparing by skills instead of by reporting line is how the unexpected candidates surface.

How often should readiness be reviewed?

Every assessment cycle, usually twice a year, and whenever a role's requirements change. A plan reviewed once a year is a snapshot, not a plan.

Succession Planning

Succession planning is the practice of identifying the roles an organization cannot leave vacant and preparing, in advance, the people who could fill them, measured by how closely each candidate's assessed skills match what the role requires.

What It Is

Succession planning answers a narrow question with a wide blast radius: if this role opened tomorrow, who could step in, and how far from ready are they? Traditional plans answer it with names on a slide, chosen by tenure, visibility, or a manager's instinct, and the plan is rarely tested until the day it is needed. A skills-based plan treats readiness as a measurement. The critical role carries a profile of required skills and certifications at required proficiency levels; each candidate carries assessed levels for the same skills; the distance between the two is the readiness gap, and the development plan is whatever closes it. Ready-now means no gaps at the role's level. Ready-soon means gaps a dated plan can close. The same comparison surfaces people nobody nominated, because it starts from evidence rather than a list of favorites. Succession is therefore not a separate system but a use of the skills inventory, role profiles, and gap analysis that already exist.

Key Facts

A critical role is one where a vacancy stops work, breaks a compliance obligation, or loses knowledge nobody else holds; most organizations have a few dozen, not hundreds.
Readiness is the gap between a candidate's assessed levels and the role's required levels, computed skill by skill, not a single potential rating.
Ready-now means no gaps at the target level; ready-soon means gaps a dated development plan can close, usually within 6 to 18 months.
Required certifications belong in the profile; a candidate with the right skills and an expired credential is not ready.
Bench depth is counted per role: fewer than two ready-now or ready-soon successors for a critical role is a risk to log, not a plan.
Expert and Mentor designations mark who can transfer knowledge before a vacancy, which is what shortens the ready-soon period.

Readiness Tiers and What Each Requires

Tier	Definition	Evidence needed	Action
Ready now	Meets the required level on every skill and holds every required certification	A current assessment, within the last cycle, on all role skills	Confirm interest; keep grades and credentials current
Ready soon	Meets most required levels; remaining gaps are one level and closable	Assessment plus a dated development plan per gap	Assign learning, pair with a Mentor, give stretch work
Development pool	Meets some required levels; gaps of two or more levels, or missing certifications	Assessment against the target role's profile	Long-horizon plan; re-assess every cycle
Not yet on the slate	Unassessed against the role, or gaps span most of the profile	None yet	Assess before excluding; a slate is only as good as its coverage

How SkillsDB Models It

SkillsDB has no separate succession module; it answers the question from the primitives it already holds. Take a critical role, Plant Maintenance Supervisor, defined as a Career with Level 3 benchmarks such as Root Cause Analysis 4 and Lockout/Tagout 5, plus a required certification. A manager assigns two candidates to that Career alongside their current one, and each candidate's Skills page shows the Level 3 benchmarks next to their manager grades: one holds Root Cause Analysis at 4 and Lockout/Tagout at 4 (one red badge, one skill short); the other sits at 3 and 3. On the manager's side, My Team Skills → Career Overview for that career reports Meets Target and Below Target percentages, and the Skills Matrix shows both candidates as rows with a red, green, or blue badge per skill. Expert and Mentor flags, applied only by managers or admins, mark who can coach them, and the Skills Flag view of the matrix lists those people. See Succession Planning and the Succession Planning feature.
