The performance-measurement and management-control division of the AGL Asset Lifecycle Guide. Division 21 establishes the digital infrastructure and data environment; Division 22 converts that data into measurable asset-performance indicators, trends, benchmarks, management reviews and improvement actions. The fundamental lifecycle relationship it manages is Asset Data → KPI → Trend → Review → Decision → Improvement → Re-measurement.
The question this division answers — How well are our AGL assets actually performing, what do the trends say against target, and what management decisions and improvement actions should that performance data drive?
Division 22 becomes the measurement layer for the entire Asset Lifecycle Guide — sitting downstream of Division 21's digital data foundation and feeding directly back into Operations, Maintenance Strategy, Reliability, Lifecycle Cost, Spare Parts, Warranty, Inspection, and Replacement Planning.
Measures the extent to which an asset is available to perform its intended function when required.
Identify assets or asset groups with unacceptable availability and determine the underlying causes.
Measures the ability of an asset to perform its required function without failure for a specified period under stated conditions.
MTBF is a key reliability KPI for repairable equipment.
MTBF should always be interpreted alongside asset population, operating conditions, failure definition, observation period, and maintenance regime — rather than being used as an isolated number.
Measures the average time required to restore an asset after a failure, according to the organization's defined measurement boundary.
Indicates how frequently failures occur within the defined asset population and observation period.
Compare failure trends for runway fixtures, taxiway fixtures, CCRs, isolation transformers, PAPI, and signs.
Measures the period during which an asset or system is unavailable for its intended function.
Reduce unnecessary downtime while maintaining safe and compliant maintenance practices.
Maintenance cost should be monitored at both asset and asset-group levels.
Maintenance-cost trends can identify assets becoming uneconomical to maintain.
Energy performance should be monitored where meaningful and measurable.
The comparison should account for operating profile and required performance.
Lifecycle cost combines the costs incurred throughout an asset's lifecycle.
Determine whether an asset is delivering acceptable lifecycle value.
The Asset Health Index provides a consolidated view of asset condition.
| Class | General Interpretation |
|---|---|
| H1 | Healthy |
| H2 | Good |
| H3 | Deteriorating |
| H4 | Poor |
| H5 | Critical |
The exact scoring methodology should be defined and controlled by the asset-management framework.
RUL estimates how long an asset can reasonably continue to provide its required function under defined conditions.
RUL is an estimate, not a guaranteed failure date.
Measure whether planned preventive-maintenance activities are completed within the organization's defined requirements.
A high PM-compliance percentage does not automatically mean good asset performance. It should be assessed alongside failure rate, availability, MTBF, condition, and maintenance effectiveness.
Track the proportion or volume of maintenance resulting from identified failures or defects requiring corrective action.
Understand whether the maintenance strategy is generating excessive reactive work.
Repeat failures are a particularly important reliability KPI.
Repeat failures should feed directly into RCA and reliability improvement programmes.
Monitor spare-parts consumption against the asset population and maintenance activity.
Replacement rate measures the rate at which assets or components are being replaced.
A rising replacement rate may indicate systemic asset deterioration.
Warranty KPIs should measure how effectively suppliers and manufacturers support the asset lifecycle.
Warranty performance can contribute to future vendor evaluation, product selection, procurement decisions, and supplier qualification.
Asset utilization measures how extensively an asset is actually used relative to its available capability or defined operating profile.
Helps determine loading, capacity, energy use, maintenance requirements, and future asset requirements.
Benchmarking compares asset performance across asset groups, locations, airports, manufacturers, models, technologies, and time periods.
Benchmarking should use consistent definitions.
The KPI dashboard should provide a consolidated view of AGL asset performance.
Monthly review should convert KPI data into management actions.
The annual review should evaluate the overall health and performance of the AGL asset portfolio.
The 22 topics, mapped against the core question each one is designed to answer.
| No. | Topic | Core Question |
|---|---|---|
| 01 | Asset Availability | Is the asset available when required? |
| 02 | Asset Reliability | Does it perform without failure over time? |
| 03 | MTBF | How often does it fail? |
| 04 | MTTR | How fast is it restored after failure? |
| 05 | Failure Rate | Where and why are failures concentrated? |
| 06 | Downtime | How much unavailable time is there, and why? |
| 07 | Maintenance Cost | What does it cost to keep this asset running? |
| 08 | Energy Consumption | How efficiently is it operating? |
| 09 | Lifecycle Cost | Is it delivering acceptable lifecycle value? |
| 10 | Asset Health Index | What condition is it in overall? |
| 11 | Remaining Useful Life | How much life does it realistically have left? |
| 12 | PM Compliance | Is planned maintenance being completed on time? |
| 13 | Corrective-Maintenance Rate | How reactive is the maintenance strategy? |
| 14 | Repeat-Failure Rate | Are the same failures recurring? |
| 15 | Spare Consumption | What is being consumed, and how fast? |
| 16 | Replacement Rate | How fast are assets being replaced, and why? |
| 17 | Warranty Performance | Are suppliers meeting their obligations? |
| 18 | Asset Utilization | How intensively is the asset actually used? |
| 19 | Performance Benchmarking | How does this compare to other assets or periods? |
| 20 | KPI Dashboard | What does the consolidated picture look like? |
| 21 | Monthly KPI Review | What management action does this month's data require? |
| 22 | Annual Asset-Performance Review | How is the whole portfolio trending year over year? |
The mandatory outputs of Division 22.
"What is not measured cannot be effectively managed, and what is measured but not reviewed cannot be effectively improved."
Division 22 should remain the performance-control and continuous-improvement layer of the AGL Asset Lifecycle Guide. Division 21 provides the digital data foundation; Divisions 19–20 provide the replacement and retirement mechanisms; Division 22 is what turns all of that recorded data into decisions.
Individual KPIs should stay visible rather than being hidden inside a single composite score. A composite Asset Performance Score is useful for portfolio-level prioritization, but it should never replace the underlying engineering evidence — availability, reliability, condition, maintainability, cost, and lifecycle status all need to remain independently inspectable.
Quick answers about Asset Performance & KPI Management in the AGL Asset Lifecycle Guide.
Division 22 is the performance-measurement and management-control division. It covers 22 topics on availability, reliability, MTBF/MTTR, failure rate, downtime, cost, energy, health index, RUL, PM compliance, spare consumption, benchmarking, KPI dashboards, and monthly/annual performance review.
It is the performance-measurement and management-control division of the guide. Division 21 provides the digital data environment, and Division 22 converts that data into measurable asset-performance indicators used for management review.
It covers asset availability (equipment, system and operational), asset reliability, MTBF, MTTR, failure rate and downtime. Downtime is broken down into planned, unplanned, corrective-maintenance, emergency and waiting-for-spares periods.
MTBF is a key reliability KPI for repairable equipment, useful for comparing assets, spotting deterioration and comparing manufacturers. MTTR measures the average time to restore an asset after a failure, according to the organization's defined measurement boundary, including detection, response, diagnosis and repair time.
Maintenance cost, preventive-maintenance compliance, corrective-maintenance rate, repeat-failure rate, spare consumption and replacement rate. Repeat failures are called out as a particularly important reliability KPI.
Lifecycle cost, energy consumption, the Asset Health Index and Remaining Useful Life (RUL), plus warranty performance and asset utilization.
Benchmarking compares asset performance across asset groups, locations, airports, manufacturers, models, technologies and time periods, for example CCR A vs CCR B or legacy fixtures vs LED.
A KPI dashboard gives a consolidated view of AGL asset performance across reliability, availability and other groups. A monthly KPI review converts KPI data into management actions by comparing current values with the previous month, target, trend and variance, and an annual asset-performance review evaluates the overall health and performance of the asset portfolio.
