Maintenance Engineering in Industry 5.0: The Maintenance Engineer as a Lifecycle Value Enabler

Maintenance Engineering has evolved from a predominantly technical discipline into a strategic capability that supports organisational performance, safety, and sustainable value creation. This evolution becomes more explicit in the context of Industry 5.0, where industrial practice is increasingly evaluated against three expectations: human-centricity, sustainability, and resilience.

For the Maintenance Engineer, this shift is highly practical. It changes the question from “How do we execute maintenance efficiently?” to “How do we assure, improve, and evidence asset performance throughout the lifecycle—while controlling risk and supporting sustainability objectives?”

A coherent normative foundation helps organisations make this change repeatable and auditable. ISO 55000 provides the principles, terminology, and outcomes orientation for asset management, while ISO 55001 specifies requirements for an Asset Management System (AMS). On the maintenance domain side, EN 17007 provides a generic maintenance process model and guidance for defining indicators, EN 17485 bridges maintenance and physical asset management decision-making, EN 17666 frames maintenance engineering across the lifecycle, and EN 15628 addresses competence requirements for maintenance personnel.

This article consolidates these elements into a Maintenance Engineer–oriented view of what “good” looks like in Industry 5.0: structured processes, competence-based execution, and feedback loops that turn operational evidence into lifecycle governance.

1. Why Industry 5.0 reframes the Maintenance Engineer’s mandate

Industry 5.0 requires organisations to demonstrate that technology and engineering decisions generate value that is not only operational, but also sustainable and socially responsible. In maintenance, that rebalancing has three concrete implications.

• Human-centricity increases the importance of transparent decision-making. The Maintenance Engineer must be able to explain why a certain strategy, interval, threshold, or intervention was selected, and how professional judgement and data were combined.
• Sustainability pushes lifecycle thinking into daily work. Maintenance decisions increasingly influence energy consumption, material use, waste generation, and circular options such as refurbishment and reuse, rather than “replace by default.”
• Resilience increases the focus on risk-based prioritisation and adaptability. Engineering work must continuously evaluate changing contexts: operational profiles, ageing behaviour, supply chain constraints, and shifting regulatory expectations.

In short, Industry 5.0 changes the Maintenance Engineer’s role from a primarily reactive optimiser to a disciplined lifecycle decision-maker who maintains a credible line of sight from strategy to execution and back to improvement.

2. Defining Maintenance Engineering for practice

A useful baseline is to separate three related concepts:

Maintenance (as a domain) includes technical, administrative, and managerial actions intended to retain or restore an item so it can perform its required function. Standardised terminology is essential, because without shared language, organisations cannot build consistent processes or performance evidence. EN 13306 provides generic terms and definitions for maintenance and maintenance management. Maintenance Engineering, in contrast, is the engineering discipline that develops and supports maintenance across the lifecycle so required functions are achieved safely, sustainably, and cost-effectively.

EN 17666 explicitly positions maintenance engineering throughout the lifecycle and links it to the assurance of dependability and a sustainable balance between performance, risk, and costs.

For the Maintenance Engineer, this definition is operationally important: it legitimises engineering involvement upstream (design and development) and downstream (disposal/transition), not only in utilisation.

3. Process architecture: why Maintenance Engineers need EN 17007 thinking

Many organisations struggle because maintenance is organised as “a set of tasks” rather than “a controlled system of processes.” This creates fragmentation: strategy documents exist, operational work happens, but the connection between them is weak and learning is slow.

EN 17007 addresses this by providing a generic description of the maintenance process and a model that supports the definition of indicators. The practical consequence for Maintenance Engineers is that work can be structured into an auditable architecture in which responsibilities, interfaces, and performance evidence become explicit.

In many implementations, the process logic is grouped into three families:

1. Management processes connect maintenance to objectives, priorities, planning principles, and performance management. If these are weak, reactive work dominates and engineering decisions become inconsistent.
2. Realisation processes cover maintenance execution and technical interventions, including inspections, corrective work, preventive work, and condition-based actions. Here, engineering quality is expressed through task design, workability, technical standardisation, and barrier integrity.
3. Support processes enable sustainable execution, including competence, tools, spares, documentation, and data quality. Support is frequently underestimated; however, weak support processes are a main driver of backlog growth, repeated failures, and low learning speed.

A process model also clarifies what should be measured. Mature maintenance engineering does not only track “how much work was done,” but also whether process performance supports lifecycle outcomes.

4. The bridge to Asset Management decision-making: EN 17485 and ISO 5500x

Maintenance Engineers often experience a practical disconnect: strategic asset intentions exist, but the prioritisation logic in day-to-day maintenance does not always reflect it.

EN 17485 specifies methods and procedures for applying physical asset management as a framework in which maintenance is taken into account as an influencing factor within strategic and tactical decisions, and in which asset management is applied to maintenance activities.

This aligns well with the ISO 55000/55001 emphasis on alignment, system thinking, and outcomes-based governance within an Asset Management System.

For the Maintenance Engineer, the key message is that maintenance engineering evidence (failure data, condition trends, maintainability constraints, risk exposure) is not merely operational reporting. It is a decision input to asset management, supporting lifecycle investment, modification strategies, and risk governance.

5. Competence as a risk control: EN 15628 in a Maintenance Engineer’s reality

Industry 5.0 increases the complexity of maintenance work: hybrid human–technology workflows, more condition monitoring data, advanced diagnostics, and increasing pressure for transparency and assurance. Under these conditions, competence becomes a critical control mechanism.

EN 15628:2025 describes the knowledge, skills, and competencies required for the qualification of maintenance personnel and indicates its use for training, skills validation, and career planning. From a Maintenance Engineer perspective, this matters because competence directly affects:

• work quality and execution variability,
• diagnostic accuracy and troubleshooting speed,
• barrier integrity and safety assurance,
• the organisation’s capacity to convert data into decisions.

If competence requirements are not explicit, maintenance becomes dependent on individuals rather than systems, which reduces repeatability and increases operational risk.

6. Maintainability as an engineering lever: design decisions that determine future maintenance burden

A mature Maintenance Engineer function seeks leverage. One of the strongest levers is maintainability—because a significant part of lifecycle maintenance effort is shaped before operation begins.

IEC 60706-2 addresses maintainability requirements and studies during design and development, including how maintainability characteristics relate to maintenance planning. This provides a rigorous justification for Maintenance Engineers to be active in early lifecycle stages:

• concept: maintainability targets, access philosophy, modular design assumptions,
• development: task feasibility, maintainability verification logic, monitoring architecture,
• realisation: validation of “as-built” against “as-designed” maintainability assumptions.

This is also where circular thinking becomes practical: design-for-disassembly, reuse options, refurbishment pathways, and materials selection that supports lifecycle value retention.

7. Practical implementation: a Maintenance Engineer’s operating rhythm in Industry 5.0

To translate the above into routine practice, many organisations benefit from formalising a small set of recurring engineering routines. The aim is not bureaucracy, but controlled learning and decision quality.

A pragmatic rhythm can include:

1. Weekly plan quality and failure review Focus: top repeating failures, quality of work orders, and “what changed” in operating context.
2. Monthly strategy and interval review for critical assets Focus: strategy fit, condition trends, failure consequences, and barrier integrity.
3. Quarterly process performance review aligned to EN 17007 logic Focus: management, realisation, and support process weaknesses and improvement actions.
4. Structured competence review (role-based) Focus: gaps against required tasks and risk exposure, aligned to EN 15628 guidance.
5. Lifecycle decision support inputs Focus: how engineering evidence informs asset decisions, consistent with EN 17485 and AMS governance.

This creates the operational form of the Industry 5.0 expectation: decisions are explainable, evidence-based, and continuously improved.

Key takeaways

• Industry 5.0 expands the Maintenance Engineer’s mandate toward lifecycle value, sustainability, and resilience outcomes.
• EN 17007 supports a process architecture that makes maintenance controllable and measurable beyond task completion.
• EN 17485 formalises maintenance as an influencing factor in strategic and tactical asset decisions.
• EN 17666 positions maintenance engineering across the full lifecycle and links it to balancing performance, risk, and cost.
• EN 15628 makes competence explicit and usable as a risk control and capability management instrument.

Closing reflection

For Maintenance Engineers, the transition to Industry 5.0 is not primarily a technology story. It is a governance story supported by technology: a move toward structured processes, explicit competence, and evidence-based feedback loops that connect operational reality to lifecycle decisions.

The organisations that mature fastest typically do not “digitise maintenance” first. They first stabilise the engineering logic—process, competence, decision interfaces—and then scale technology on top of that foundation.
