The correct hierarchy is:
- Governance and contractual discipline
- Engineering integrity and system condition
- Performance measurement, including Key Performance Indicators (KPIs)
KPIs remain valid tools when properly designed and aligned. However, when misapplied, they can distort behaviour, obscure risk, and misrepresent actual performance.
The governing principle is clear:
Performance can only be measured against work that is formally defined, technically justified, contractually approved, and properly resourced.
Within this framework:
- Properly engineered planned maintenance establishes the baseline for safe, stable, and compliant operation
- Governance, ethics, and accountability define how performance is delivered
- Performance beyond the baseline represents additional engineered value
Maintenance KPIs are widely used across healthcare, industrial, and commercial environments to assess operational performance. These typically focus on uptime, maintenance completion, response times, and cost efficiency.
However, engineering systems operate under dynamic conditions and degrade progressively due to load, environment, and lifecycle factors. Conventional KPI frameworks often fail to capture this complexity, as they measure activity rather than system condition and rely heavily on lagging indicators.
This creates a structural gap between reported performance and actual engineering reality.

Core Principle of Performance Measurement
Performance must be anchored to a single governing principle: Performance can only be measured against work that is formally defined, technically justified, contractually approved, and properly resourced.
Any deviation introduces:
- Technical risk
- Commercial misalignment
- Governance breakdown
- Distorted reporting
This principle protects all stakeholders and ensures performance measurement reflects reality.
Performance Governance Hierarchy
Effective performance management must follow a strict order of control:
-
Governance and contractual discipline
Defines scope, approvals, accountability, and auditability
-
Engineering integrity and system condition
Ensures technical correctness, asset protection, and risk control
-
Performance measurement (KPIs)
Provides visibility and trend indication
KPIs must operate within governance and engineering frameworks, not override them.
Limitations of Traditional KPI Frameworks
Traditional KPI systems:
- Measure task completion rather than system performance
- Depend on lagging indicators
- Simplify complex engineering behaviour
- Provide limited visibility into degradation and risk
Systems can meet KPI targets while operating inefficiently or outside design intent.
Work Behavioural and Operational Distortion
Rigid KPI environments can drive unintended behaviours:
- Optimisation for metrics rather than outcomes
- Checklist-driven maintenance without validation
- Reclassification of work to protect KPI results
- Underreporting of emerging issues
These behaviours reduce transparency and compromise engineering integrity.
“Near Death” KPI Scenarios
Poorly designed KPI frameworks can create high-risk operating conditions:
- Under-maintenance driven by cost targets
- Artificial uptime masking system stress
- Reduced manpower to meet productivity metrics
- Deferred lifecycle interventions
- Compliance reported without technical validation
These scenarios result in systems that appear compliant but are operationally unstable.
KPI Misuse in Supplier Management
KPI frameworks become problematic when:
- Accountability exceeds supplier control
- Performance expectations are not commercially aligned
- Enforcement is inconsistent or informal
- Penalties outweigh improvement mechanisms
This leads to defensive behaviour, reduced transparency, and increased risk.
Scope Control and Contractual Discipline
A fundamental rule must be maintained: Performance can only be measured against a formally approved scope. Meeting minutes and informal communications do not constitute contractual approval
No additional scope shall be executed, reported, or measured unless formally approved, commercially aligned, and documented through contract variation. Failure to enforce this creates KPI distortion and governance breakdown.
Planned Maintenance as the Performance Baseline
Properly defined planned maintenance establishes the operational baseline. A valid maintenance plan must be:
-
Engineering-based
Aligned with OEM requirements and system design
-
Risk-based
Prioritised according to asset criticality
-
Lifecycle-aligned
Supporting long-term asset condition
-
Compliance-assured
Meeting statutory and safety obligations
Execution ensures: system stability, controlled degradation, regulatory compliance. This defines sufficient baseline performance.
Benefits of Reducing Dependence on Strict KPIs
Reducing reliance on rigid KPI frameworks enables:
- Improved engineering decision-making
- Accurate visibility of system condition
- Enhanced lifecycle asset protection
- More stable and predictable operating costs
- Greater transparency and auditability
- Increased operational resilience
- Elimination of KPI-driven behavioural distortion
Governance, Ethics, and Values as Core Performance Dimensions
Performance must include governance and ethical accountability: Compliance integrity, Transparency of reporting, Ethical conduct, Auditability, Scope discipline.
Values must be operationalised:
- Doing what is documented
- Documenting what is done
- Escalating issues early
- Acting in long-term interest
Performance without these elements is incomplete.
10 Core Functions of Responsibility and Accountability
A complete performance framework includes:
- Engineering integrity
- Risk ownership
- Lifecycle asset stewardship
- Quality of execution
- Decision traceability
- Data integrity
- Continuous improvement
- Resource responsibility
- Stakeholder alignment
- Operational resilience
These define true accountability.
1. Engineering Outcome Indicators
Performance should be assessed through outcome-based indicators:
- System condition trends
- Reduction in failure patterns
- Lifecycle extension indicators
- Energy performance stability
- Risk exposure reduction
These reflect real performance, not activity.
Engineering-Led Performance Framework
An effective model integrates:
- System condition visibility
- Risk-based maintenance
- Predictive monitoring and analytics
- Governance-driven reporting
KPIs function as supporting tools within this framework.
Strategic Implications
Clients
Gain transparency, reduce lifecycle risk, and improve system reliability
Operators
Operate with clarity, fairness, and engineering alignment
Investors
Benefit from asset protection, predictable cost behaviour, and reduced exposure
Rigid KPI-driven models create the illusion of control but often fail to reflect engineering reality.
Performance must be redefined through: Governance and contractual discipline, Engineering integrity, Transparent and auditable reporting, Outcome-based measurement.
Planned maintenance establishes the baseline.
Governance and ethics define accountability.
Engineering excellence delivers value beyond that baseline.
KPIs remain tools, not the system.
True performance is achieved when systems operate reliably, risks are visible, and value is created through disciplined, engineering-led execution.
