A different question is equally important:

Where does talent have the greatest impact on business performance?

Not every role contributes in the same way, and not every position carries the same level of strategic or operational dependency. A highly capable employee in a business critical role can have a very different impact from an equally engaged employee in a role with limited influence on a critical business outcome.

This is why organisations need to understand critical roles, critical capabilities, and star performers alongside broader workforce measures.

They are not necessarily the most senior roles.

A critical role could be:

• A specialist technology position
• A revenue generating role
• A plant or operational leadership position
• A role responsible for regulatory compliance
• A position holding scarce technical knowledge
• A role responsible for a strategically important customer relationship

The defining characteristic is not job title.

It is business dependency.

The first role supports a routine administrative process with several available replacements.

The second role manages a highly specialised system that supports a critical business operation, and only a small number of employees possess the required expertise.

Both employees matter.

But the business risk associated with losing the second capability may be substantially higher.

This is why workforce management should consider role criticality and capability scarcity, rather than treating every position as having identical workforce risk.

However, an organisation can have strong overall engagement while still facing significant capability risk.

For example, employees may report high engagement while:

• Critical roles remain vacant
• Specialist capabilities are concentrated among a few people
• Succession coverage is weak
• High performers are leaving critical positions
• Important skills are not available where demand is increasing

Engagement therefore answers one question:

How are employees experiencing the organisation?

Critical role analysis addresses another:

Does the organisation have the capabilities required to execute its strategy?

Both perspectives can be valuable, but they measure different things.

Leadership can assess roles against factors such as:

• Revenue contribution
• Customer impact
• Operational dependency
• Scarcity of required skills
• Regulatory or compliance exposure
• Difficulty and time required to replace the capability
• Impact of vacancy
• Availability of internal successors
• Strategic importance of the role

This creates a more evidence based approach than simply defining senior positions as critical.

But high performance alone does not automatically make someone strategically critical.

Consider two high performers.

One works in a role where several employees possess similar capabilities and replacement is relatively straightforward.

Another performs at a high level in a role requiring scarce expertise that is directly connected to a strategic business priority.

The second employee may represent greater workforce risk.

This is why organisations should analyse performance and role criticality together.

Role Criticality × Capability Scarcity × Performance × Replacement Difficulty

This creates a more useful view of workforce risk than relying on one employee metric.

For example, a critical role with no ready successor and only one qualified internal employee should receive different attention from a non critical role with multiple qualified successors.

The objective is not to label employees.

It is to understand where the organisation has concentrated capability risk.

Potential interventions include:

• Targeted succession planning
• Accelerated development
• Internal mobility
• Skills development
• Knowledge transfer
• Targeted recruitment
• Retention strategies
• Workforce redesign
• Automation where appropriate

For example, if a critical capability depends heavily on two experienced employees, the organisation could create a knowledge transfer and succession programme before the capability becomes a business continuity risk.

A critical role approach introduces greater prioritisation.

The organisation can ask:

Which capabilities are most important to our strategy?

Where are those capabilities located?

How concentrated are they?

What happens if we lose them?

Can we build or acquire replacements?

This allows talent management investment to become more closely connected to business requirements.

Engagement remains an important part of understanding workforce experience.

The issue is not choosing between engagement and critical role analysis.

Instead, organisations should connect multiple perspectives:

Employee Experience + Performance + Critical Roles + Capability Risk + Business Priorities

For example, low engagement within a critical role population may represent an important retention risk.

Similarly, high engagement combined with weak succession coverage may indicate that the organisation has engaged employees but insufficient resilience around critical capabilities.

The value comes from connecting the signals.

This can help leaders identify:

• Where critical skills exist
• Which roles depend on scarce capabilities
• Where succession gaps exist
• Which employees have transferable skills
• Where development investment could address capability gaps
• Where workforce risks are concentrated

AI can further support skills inference, talent matching, workforce scenario analysis, and identification of emerging capability gaps.

Technology should support the strategy rather than replace leadership judgement.

But workforce strategy needs to go further.

The more strategic question is:

Are the people and capabilities that matter most to the business positioned to deliver the outcomes the organisation needs?

That requires organisations to understand critical roles, identify scarce capabilities, recognise high performance, assess succession risk, and connect talent decisions with business priorities.

The result is a more targeted talent management strategy that focuses not only on how employees feel, but also on where capability creates value and where capability risk could affect the business.

• Critical roles are defined by business dependency, not simply seniority.
• Engagement and employee performance measure different aspects of workforce health.
• Star performers in critical roles can represent concentrated capability value and risk.
• Critical role strategy should consider business impact, scarcity, performance, and replacement difficulty.
• Talent investment can be prioritised around roles and capabilities that matter most to business strategy.
• HCM technology can connect skills, performance, succession, mobility, and workforce planning data.
• Engagement should remain part of the workforce picture, but it should not be the only lens through which talent risk is assessed.
