Workforce succession coverage calculator

Calculate uncovered roles and backup concentration counts with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use uncovered roles and backup concentration counts to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

JSON Critical roles [role ID,ready backup person IDs]
[["A",["P1"]],["B",[]],["C",["P1","P2"]]]
Uncovered roles
["B"]
Backup concentration counts
[["P1",2],["P2",1]]
Roles with ready backup (%)
66.666667

Try another scenario

JSON Critical roles [role ID,ready backup person IDs]
[["A",["P1"]],["B",["P3"]],["C",["P1","P2"]]]
Uncovered roles
[]
Backup concentration counts
[["P1",2],["P2",1],["P3",1]]
Roles with ready backup (%)
100
Calculation method

Calculation method

Uncovered roles

J([r[0] for r in a if not r[1]])

Backup concentration counts

J([[p,sum(p in r[1] for r in a)] for p in sorted({p for r in a for p in r[1]})])

Roles with ready backup (%)

100*sum(bool(r[1]) for r in a)/len(a)

Symbols and units

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Calculation steps and notation

sum(list) adds all entries in the list.

Assumptions & limits

Assumptions & limits

  • Only user-designated ready backups count. This audits designations without judging readiness or future performance. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
