Why specialisation is a key lever for availability, risk and profitability today<\/h2>\n\n\n\n
<\/div>\n\n\n\n

1. executive summary<\/h2>\n\n\n\n

Management guiding principle:<\/strong><\/p>\n\n\n\n

\n

External technical service is not an operational stopgap, but a strategic management tool for modern maintenance organisations.<\/em><\/p>\n<\/blockquote>\n\n\n\n

The maintenance of rail vehicles is facing a structural reorganisation. Technological complexity, increasing regulatory requirements, heterogeneous fleet structures and a worsening shortage of skilled workers are permanently changing the economic and organisational framework conditions. At the same time, expectations of vehicle availability, predictable life cycle costs and stable operating processes are increasing. In this environment, traditional make-or-buy discussions are becoming increasingly meaningless.<\/p>\n\n\n\n

External technical services in rail vehicle maintenance are increasingly developing from an operational support service into a strategic management tool for availability, risk and profitability.<\/p>\n\n\n\n

The central management question today is no longer whether maintenance services should be provided internally or externally, but rather how risks can be systematically controlled, availability stabilised, compliance ensured and capital used efficiently. External technical services are not an operational stopgap, but a strategic instrument for stabilising operations, organisation and key performance indicators.<\/p>\n\n\n\n

A deliberately designed hybrid maintenance model, in which standard services are provided internally and specialised services are provided externally, enables a transformation of fixed cost structures into variable, needs-based expenses. At the same time, downtimes can be reduced, organisational resilience increased and responsibilities structured more clearly.<\/p>\n\n\n\n

For decision-makers in workshops, at operators, leasing companies, OEMs and system and component manufacturers, this means that it is not maximum internal capacity that increases stability today, but a consciously managed combination of internal basic capability and external specialisation. The question is not \u201eexternal or internal\u201c, but \u201ewhich expertise belongs where strategically\u201c.<\/p>\n\n\n\n

<\/div>\n\n\n\n

2. from the personnel issue to the system issue: the new context of rail vehicle maintenance<\/h2>\n\n\n\n

2.1 Technical, regulatory and organisational shifts<\/h3>\n\n\n\n

Management guiding principle:<\/strong><\/p>\n\n\n\n

\n

Maintenance is no longer an isolated workshop function, but an integrated management task.<\/em><\/p>\n<\/blockquote>\n\n\n\n

Rail vehicle maintenance has changed fundamentally in recent years. Vehicles today are highly integrated systems in which mechanics, electrics, electronics and software are closely interlinked. Subsystems such as doors, air conditioning systems, brakes or clutches have their own control logic, diagnostic systems and interfaces to higher-level vehicle computers. The result is increasing technical complexity combined with a growing number of variants.<\/p>\n\n\n\n

At the same time, regulatory requirements have become more stringent. Documentation, traceability, proof of qualification and auditability have become integral components of maintenance services. Errors in execution or documentation not only have technical implications, but also liability and authorisation implications.<\/p>\n\n\n\n

In organisational terms, workshops and operators are under additional pressure. Fluctuating capacity utilisation, tight time frames, increasing expectations of availability and scarce personnel resources require significantly greater flexibility than in the past. Maintenance has therefore become a systemic management task.<\/p>\n\n\n\n

<\/div>\n\n\n\n

2.2 Why \u201eDo we have enough people?\u201c is the wrong key question<\/h3>\n\n\n\n

Management guiding principle:<\/strong><\/p>\n\n\n\n

\n

It is not personnel capacity that determines stability, but the confident handling of critical dependencies.<\/em><\/p>\n<\/blockquote>\n\n\n\n

In many organisations, the current situation is still primarily discussed as a personnel problem. However, this perspective falls short. The decisive factor is not the number of employees, but the ability to make critical situations manageable. Rather, the focus is on the following questions:<\/p>\n\n\n\n

    \n
  • How high is the risk of unplanned downtime in the absence of specialised expertise?<\/li>\n\n\n\n
  • How stable is technical availability as a key performance indicator?<\/li>\n\n\n\n
  • How much capital is tied up in personnel, training, tools and test equipment?<\/li>\n\n\n\n
  • How resilient is the organisation to the loss of individual key personnel?<\/li>\n<\/ul>\n\n\n\n

    The key finding is that specialised rail vehicle maintenance is not a personnel issue, but a risk, availability, compliance and capital issue. External technical services are a structural lever for managing these dimensions in a targeted manner.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    3. market environment: why \u201edoing everything yourself\u201c is coming up against structural limits<\/h2>\n\n\n\n

    3.1 Fleet heterogeneity, variant diversity and rare special cases<\/h3>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Complexity does not arise in day-to-day business, but in mastering the exceptions.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    Many operators and workshops today manage fleets with different vehicle types, years of manufacture and manufacturers. Added to this are retrofit measures, software versions and customised adaptations. Even within one model series, there are often several variants. For maintenance, this means a considerable increase in complexity.<\/p>\n\n\n\n

    Certain error patterns or specialised work occur only rarely, but have a high impact on availability and operation in the event of an incident. The learning curve of internal teams is flat in such cases as there is a lack of repetition. Knowledge remains fragmented and is often tied to individual people.<\/p>\n\n\n\n

    Permanent internal provision of these skills is economically inefficient and organisationally risky.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    3.2 Regulation, verification and audit pressure<\/h3>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Regulatory security is created through clear structure, not operational improvisation.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    In addition to the technical complexity, regulatory pressure is also increasing. Maintenance work must not only be carried out correctly, but must also be fully documented and auditable. Responsibilities must be clearly assigned, qualifications must be verified and processes must be traceable. These requirements apply regardless of whether services are provided internally or externally.<\/p>\n\n\n\n

    External technical services can offer added value here, provided they have established processes, clear interfaces and auditable documentation standards. The decisive factor is not the outsourcing of responsibility, but its clear demarcation.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    4 Labour market and demographics as a structural bottleneck<\/h2>\n\n\n\n

    4.1 Key person risk and knowledge concentration<\/h3>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Knowledge that only exists in people's heads is an existential risk but not an asset.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    The shortage of skilled labour in rail vehicle maintenance is structural. Many highly qualified specialists are about to retire, while the availability of young talent is limited. In many organisations, critical knowledge is concentrated in just a few people. This dependency poses a considerable risk.<\/p>\n\n\n\n

    Absences due to illness, redundancies or retirement lead directly to gaps in expertise. In critical situations, this can lead to extended downtimes, quality problems or postponed deadlines.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    4.2 Why external services create systemic resilience<\/h3>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Organisational resilience is created through redundancy in expertise, not through individual resilience.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    External technical services enable organisational expertise. Expertise is no longer tied to individual people, but is available via teams, processes, training systems and experience structures. This creates redundancy and scalability at organisational level. For the maintenance organisation, this means greater resilience. Critical competences are available even if internal resources are temporarily unavailable or overloaded.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    5. rethinking make-or-buy: the hybrid maintenance model in rail vehicle maintenance<\/h2>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Blanket outsourcing of maintenance services is just as risky as trying to provide all specialised skills in-house on a permanent basis.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    A sustainable approach lies in a hybrid maintenance model that specifically combines internal core competencies with external specialisation. This model is based on a consciously defined maintenance specialisation portfolio that determines which services are strategically anchored internally and which are supplemented externally depending on the situation or skills.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    5.1 Services with meaningful internal provision<\/h3>\n\n\n\n

    Management guiding principle:<\/strong><\/p>\n\n\n\n

    \n

    Internal core expertise ensures stability,<\/em> Availability and agility in daily regular operation.<\/em><\/p>\n<\/blockquote>\n\n\n\n

    Services with sensible internal provision are characterised by high regularity, predictable capacity utilisation and close integration with operations. You benefit in particular from local fleet and system expertise, short decision-making paths and direct controllability in day-to-day business.<\/p>\n\n\n\n

    These include in particular<\/p>\n\n\n\n

      \n
    • Serial maintenance and regular maintenance work<\/li>\n\n\n\n
    • Activities with stable capacity utilisation and predictable cycles<\/li>\n\n\n\n
    • Fleet management, maintenance planning and operational control<\/li>\n\n\n\n
    • Working with a strong dependence on local infrastructure and company-specific expertise<\/li>\n<\/ul>\n\n\n\n

      These services form the backbone of stable and reliable regular operations and should be permanently anchored internally.<\/p>\n\n\n\n

      <\/div>\n\n\n\n

      5.2 Services with meaningful external supplementation<\/h3>\n\n\n\n

      Management guiding principle:<\/strong><\/p>\n\n\n\n

      \n

      Targeted external specialisation increases the robustness of the organisation in complex exceptional cases.<\/em><\/p>\n<\/blockquote>\n\n\n\n

      External services are useful where high system or product complexity, low repetition frequency or special resource requirements make it difficult to perform economically or organisationally in-house.<\/p>\n\n\n\n

      The following areas in particular can be efficiently covered externally:<\/p>\n\n\n\n

        \n
      • Specialised trades with high system, technology or manufacturer complexity<\/li>\n\n\n\n
      • Rare but critical special cases and structured troubleshooting<\/li>\n\n\n\n
      • Overhauls with long cycles for small or heterogeneous fleets<\/li>\n\n\n\n
      • Covering capacity peaks through campaigns, retrofit projects or cycle overlaps<\/li>\n<\/ul>\n\n\n\n

        External technical service thus becomes a conscious portfolio decision and not a reactive emergency measure.<\/p>\n\n\n\n

        <\/div>\n\n\n\n

        5.3 Decision framework: Which expertise belongs where?<\/h3>\n\n\n\n
        \n

        Management guiding principle:<\/strong>
        Strategic stability is created through the deliberate allocation of competences in rail vehicle maintenance, not through blanket in-house services or complete outsourcing.<\/em><\/p>\n<\/blockquote>\n\n\n\n

        A compact evaluation system with 20 decision criteria, each rated with 1 to 5 points, is suitable for making make-or-buy decisions in rail vehicle maintenance in a structured and comparable manner.
        Here, 1 point stands for clear internal service provision and 5 points for the targeted use of external technical services.<\/p>\n\n\n\n

        The criteria are assigned to five dimensions:<\/p>\n\n\n\n

          \n
        • Expertise & know-how<\/li>\n\n\n\n
        • Volume & learning curve<\/li>\n\n\n\n
        • Economy & Resources<\/li>\n\n\n\n
        • Operation & Organisation<\/li>\n\n\n\n
        • Risk, quality & responsibility<\/li>\n<\/ul>\n\n\n\n

          Internal expertise, system and variant complexity, frequency and stability of service requirements, capital and resource commitment, predictability, speed, legal certainty and impact on vehicle availability are among the factors assessed.<\/p>\n\n\n\n

          The maximum score is 100 points:<\/p>\n\n\n\n

            \n
          • \u2264 40 points: <\/strong>Internal performance makes sense<\/li>\n\n\n\n
          • 41-60 points: <\/strong>Hybrid maintenance model<\/li>\n\n\n\n
          • > 60 points: <\/strong>External prioritisation<\/li>\n<\/ul>\n\n\n\n

            The system creates transparency and supports well-founded, cross-role decisions.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            6. profitability: fixed costs, opportunity costs and capital commitment<\/h2>\n\n\n\n

            6.1 Why hourly rates are the wrong benchmark<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            Cost comparisons without taking into account capital commitment and availability lead to strategically wrong decisions.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            Internal services often appear more favourable, as no external hourly rates are incurred. However, this view falls short of the mark. Internal special competences cause high fixed costs, regardless of their actual utilisation. These include personnel costs, training, recertification and investment in tools and test equipment.<\/p>\n\n\n\n

            In addition, there is a loss of strategic benefits: capital, management attention and specialised resources are tied up without any continuous or scalable added value being generated. These tied-up resources are therefore not available for higher-priority tasks such as increasing availability, process stabilisation or fleet optimisation.<\/p>\n\n\n\n

            A pure comparison of hourly rates therefore fails to recognise the actual economic and operational effects of service allocation and leads to systematically distorted make-or-buy decisions.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            6.2 The business logic: fixed cost trap vs. variable agility<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            Specialisation follows a break-even logic: the internal development of specialised expertise requires sufficient scaling, otherwise it becomes a cost trap.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            The decision in favour of external technical services is primarily a decision about the cost structure. The economic break-even point occurs where the permanent provision costs for rarely required specialised skills exceed the selective costs of an external expert.<\/p>\n\n\n\n

            In modern maintenance, this point is increasingly shifting. Technological complexity is increasing, while the frequency of specific faults per vehicle remains low. As a result, the internal marginal costs per use increase significantly. A hybrid model optimises the total cost of ownership by keeping the internal base load stable and externalising the \u201ecost peaks\u201c of specialisation.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            6.3 Capital allocation, mean time to repair (MTTR) and economic effect<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            Availability is the most economically effective lever for securing the return on maintenance.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            External services convert fixed costs into variable, demand-related costs. More decisive than the cost rate is the effect on the mean time to repair (MTTR) in rail vehicle maintenance. Shorter downtimes have a direct impact on availability, operating costs and contract stability. In many cases, the avoided downtime costs significantly exceed the external service costs.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            7. availability as a key performance indicator in operations and fleet management<\/h2>\n\n\n\n

            7.1 MTTR as a key performance indicator<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            The speed of troubleshooting (MTTR) is strategically more relevant than the nominal cost rate of a labour hour.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            MTTR is the key operational indicator in a consistently availability-orientated maintenance management system. It determines how quickly vehicles can be returned to operation after malfunctions and therefore has a direct impact on cycle stability and performance fulfilment.<\/p>\n\n\n\n

            External specialists often have cross-product, cross-system and cross-manufacturer experience from comparable application scenarios. As a result, recurring error patterns are recognised more quickly, incorrect measures are avoided and repairs are implemented in a more targeted manner. A higher first-time fix rate shortens the recovery time and reduces the MTTR in the long term - regardless of the pure hourly rate.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            7.2 Effects on operations, contracts and asset value<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            Maximum vehicle availability actively protects revenues, avoids penalties and secures long-term asset values.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            High vehicle availability stabilises operations and increases the predictability of rotations and resources. At the same time, it reduces the likelihood of contractual penalties, replacement transport and unplanned additional costs.<\/p>\n\n\n\n

            Availability is a key economic lever, particularly in leasing, operator and availability models. It not only influences short-term revenues and customer satisfaction, but also the long-term asset value of the vehicles through lower consequential damage, predictable utilisation and a sustainable maintenance strategy.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            8. risk, resilience and compliance logic<\/h2>\n\n\n\n

            8.1 External service as a risk management tool<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            External service partnerships act as a structural risk buffer against unforeseeable peak loads.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            External technical services specifically expand the internal organisation with additional capacity and specialised expertise. They make it possible to absorb short-term load peaks, project-driven special events or unexpected disruptions without jeopardising the stability of regular operations.<\/p>\n\n\n\n

            They also reduce operational risks arising from staff shortages, key competences or absences due to illness. As a scalable addition to internal maintenance, external service partnerships help to secure deadlines, reduce dependencies on individuals and maintain the overall availability of the fleet even under exceptional conditions.<\/p>\n\n\n\n

            <\/div>\n\n\n\n

            8.2 Responsibility, liability and auditability<\/h3>\n\n\n\n

            Management guiding principle:<\/strong><\/p>\n\n\n\n

            \n

            Clearly defined interfaces and interface agreements increase compliance and create legal clarity.<\/em><\/p>\n<\/blockquote>\n\n\n\n

            In the ECM system for rail vehicle maintenance, control, approval and responsibility clearly remain with the keeper or operator organisation. External services expand operational efficiency, not the responsibility structure.<\/p>\n\n\n\n

            A clear definition of interfaces is a prerequisite. Diagnostics, approvals, documentation and responsibility must be clearly regulated. Properly integrated, external service increases auditability instead of weakening it.<\/p>\n\n\n\n

            Compliance in maintenance is not a product of chance, but the result of clearly defined transfers of responsibility. In the context of the ECM guidelines and taking into account the VPI guidelines, the interface agreement is the central control instrument for ensuring this demarcation.<\/p>\n\n\n\n

            This explicitly regulates:<\/p>\n\n\n\n

              \n
            • The technical delimitation of the scope of work.<\/li>\n\n\n\n
            • The sovereignty over the release for use (return to service).<\/li>\n\n\n\n
            • Data transfer to the leading maintenance system.<\/li>\n\n\n\n
            • Complete traceability (Traceability) <\/strong>of the components used.<\/li>\n<\/ul>\n\n\n\n

              This allows the external service provider to be seamlessly integrated into the operator's safety management system (SMS) without diluting ECM responsibility.<\/p>\n\n\n\n

              <\/div>\n\n\n\n

              9. role of purchasing in external technical service<\/h2>\n\n\n\n

              Management guiding principle:<\/strong><\/p>\n\n\n\n

              \n

              Value is created by contract design, not by the lowest hourly rate.<\/em><\/p>\n<\/blockquote>\n\n\n\n

              In modern maintenance organisations, purchasing takes on the role of a business partner to the workshop and ECM. External technical services are not controlled via individual prices, but via structured service contracts that secure binding capacity, quality, speed and compliance. The aim is to integrate external services as a strategic addition to the internal organisation.<\/p>\n\n\n\n

              <\/div>\n\n\n\n

              9.1 SLA design and value proposition<\/h3>\n\n\n\n

              Service Level Agreements (SLAs) define the operational reliability of external services in the event of regular and disruptive incidents. Key elements are clearly regulated response times up to qualified diagnosis, binding on-site times and target values for the restoration of operational capability based on the MTTR. These are supplemented by defined capacity windows, regulations for peak loads and clear service windows including operational framework conditions.<\/p>\n\n\n\n

              Control-relevant KPIs<\/p>\n\n\n\n

              Performance promises are made controllable via a consistent set of key figures. These include in particular<\/p>\n\n\n\n

                \n
              • First time fix rate, repeat errors and diagnostic throughput time<\/li>\n\n\n\n
              • Documentation lead time up to the auditable report<\/li>\n\n\n\n
              • On-time delivery, quality indicators and parts availability<\/li>\n\n\n\n
              • MTTR curve per subsystem and costs per hour of downtime avoided<\/li>\n<\/ul>\n\n\n\n

                These key figures link service performance directly with availability and cost-effectiveness.<\/p>\n\n\n\n

                <\/div>\n\n\n\n

                9.2 Capacity, prices and governance<\/h3>\n\n\n\n

                Service contracts secure capacities through reserved hourly quotas, defined scaling options for campaigns and transparent skill matrices.<\/p>\n\n\n\n

                In practice, there are different remuneration approaches that vary depending on the scope of services, risk distribution and organisational maturity. The decisive factor is that the remuneration model is adapted to the specific requirements of the operator and external service provider and supports transparent and controllable service provision.<\/p>\n\n\n\n

                Clear governance regulations ensure ECM conformity, auditability and the secure handling of data, intellectual property and obsolescence. In this way, procurement does not treat external technical services as a cost item, but as a strategic reserve of capacity and expertise with a measurable effect on availability, risk and capital commitment.<\/p>\n\n\n\n

                <\/div>\n\n\n\n

                10. typical practical and application scenarios from maintenance<\/h2>\n\n\n\n

                10.1 Quick error cause instead of days of trial and error<\/h3>\n\n\n\n

                Management guiding principle:<\/strong><\/p>\n\n\n\n

                \n

                Targeted expert diagnosis replaces lengthy search processes and minimises expensive downtime chains.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                A recurring error in a subsystem leads to long search times. The internal team replaces components without finding the cause. An external specialist recognises the pattern within a short time, rectifies the cause in a targeted manner and significantly reduces downtime.<\/p>\n\n\n\n

                Key economic point: Savings on downtime and follow-up costs.<\/p>\n\n\n\n

                <\/div>\n\n\n\n

                10.2 Overhaul capacity with cycle overlap<\/h3>\n\n\n\n

                Management guiding principle:<\/strong><\/p>\n\n\n\n

                \n

                External capacity buffers ensure that deadlines are met when internal resources reach their scalable limits.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                The overhaul cycles of several vehicle fleets overlap. By outsourcing defined components to an external partner, the overall schedule remains stable.<\/p>\n\n\n\n

                Key economic point: External service as a flexible capacity buffer.<\/p>\n\n\n\n

                Strategic modernisation must not fail due to day-to-day operations, but requires a clear focus on special projects.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                An upgrade project is implemented externally while the internal team maintains standard operations. Deadlines and quality remain stable.<\/p>\n\n\n\n

                Key economic point: Reduction of project and availability risks.<\/p>\n\n\n\n

                11 Outlook: Predictive maintenance and the role of external data specialists<\/h2>\n\n\n\n

                Digitalisation does not require new tools, but rather the seamless integration of data expertise into the service process.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                The transformation from \u201efix-on-failure\u201c to condition-based maintenance (CBM) is changing the requirements for external services once again. In an Industry 4.0 environment, external partners are no longer just booked for \u201escrewing\u201c, but as data interpreters and system analysts.<\/p>\n\n\n\n

                Modern maintenance strategies use external expertise to translate sensor data and diagnostic codes into proactive maintenance events. The external service of the future not only provides the repair, but also the algorithm for avoiding breakdowns. A symbiosis that drives fleet availability towards 100%.<\/p>\n\n\n\n

                12 Conclusion: External technical service as a stability instrument<\/h2>\n\n\n\n

                Management guiding principle:<\/strong><\/p>\n\n\n\n

                \n

                Strategic maintenance is the art of making technological complexity manageable through intelligent partnerships.<\/em><\/p>\n<\/blockquote>\n\n\n\n

                External technical service in railway vehicle maintenance is not a sign of a loss of control, but an expression of a professional maintenance strategy. Used correctly, it increases availability, reduces risks, stabilises compliance and improves capital allocation.<\/p>\n\n\n\n

                Organisations that continue to regard external specialisation as an exception are tacitly increasing their availability and liability risk.<\/p>\n\n\n\n

                The decisive question is not \u201eexternal or internal\u201c, but rather: Which expertise makes strategic sense internally and which is specifically supplemented externally?<\/p>","protected":false},"excerpt":{"rendered":"
