Maintenance, repair and overhaul
Late parts, engineering queries and findings during inspection can disrupt a detailed maintenance plan. Duggan connects readiness, execution and support-shop flow so the operation can see constraints earlier and respond with a defined plan.
Where we start
Discuss the asset or maintenance family, turnaround performance and recurring interruptions. The starting scope connects the main maintenance work with support shops, engineering, material readiness and the decisions that affect release back to the customer.
What we do together
Design the flow from preparation through completion, including work discovered after inspection. Make task readiness and daily progress visible, define responses to disruption and connect supporting functions. Education and practical implementation support help technicians and leaders use the operating system.
What this can enable
Reduce avoidable waiting and stop-start work, improve schedule visibility and make better use of available maintenance capacity. Outcomes are assessed against comparable work families and a clear baseline, separating elapsed turnaround from technician effort and changes in work scope.
Scope, deliverables and success measures are agreed around your operation.
The main maintenance flow and its supporting functions form one Customer Delivery System. Task sequence, readiness and response requirements connect to the asset’s delivery commitment.
Recurring findings can inform planned work. New findings need assessment, authorization and a route for material, skills and decisions. The design makes the effect on the remaining sequence visible.
Component repair, inspection and engineering queues affect work at the asset. Defined turnaround requirements and visible connections help support functions respond to the maintenance need.
Technicians and leaders learn the expected flow, how to recognize disruption and which response they own. Technical decisions and release authority remain with the maintenance organization.
Aircraft checks
Reported C-check lead time in an anonymized aircraft maintenance engagement: approximately 30% lower after connecting readiness, hangar execution and support shops.
Marine service
Reported year-over-year inspection throughput in an anonymized marine service engagement, supported by connected planning, visual execution and clearer task readiness.
Rail overhaul
Reported power-car overhaul lead time: 40% lower. Technician effort also fell from 6,000 to 4,000 hours per overhaul; hours and elapsed days are separate measures.
Reported in Duggan’s anonymized engagement accounts. These are different maintenance scopes and are not a universal improvement guarantee.
Parts and consumables ready for the work.
Current instructions, scope and authorized decisions.
The right tools, available where needed.
Suitable equipment and available capability.
The required skills and authorized capability.
Each input has its own preparation path. Connecting their readiness to the task helps expose constraints before they interrupt maintenance.
Agree the maintenance family, current performance and support dependencies. Establish comparable baseline measures.
Define readiness, execution and support flows, including assessment and response routes for work arising.
Educate the workforce, establish visible controls and agree implementation ownership and support.
Assess repeated comparable events, exceptions and operating responses before planning wider deployment.
The proposal defines the deliverables, responsibilities and support cadence. A defined pilot can provide a starting point for wider deployment.
Engagement example
The published case links maintenance readiness, visual execution and support-shop turnaround to aircraft checks.
The case reports a 30% reduction in C-check turnaround on the pilot line. It is an engagement-specific result.

“Their focus on high participation built strong buy-in and a common language across the shop floor.”

Planning and maintenance systems can support readiness, work status and decision timing. Duggan defines the operating requirements so digital changes reinforce the flow. New software development, integrations and ongoing IT support are separately defined with the responsible technology specialists.
Readiness is an early-warning process. Where induction must proceed with unresolved inputs, the design makes exceptions, ownership and recovery needs explicit. It does not override mandatory maintenance or technical requirements.
Distinguish recurring findings from genuinely uncertain scope. Connect technical assessment and authorization to material, skills and the remaining sequence. Significant changes may require revised delivery expectations.
GTT is a defined turnaround commitment within the operating design. Work families, capability and operating assumptions must support it, with a response to exceptions. It is not a promise of the same percentage improvement for every engagement.
No. Maintenance tasks vary in work content, dependencies and skills. The execution sequence and review cadence reflect that variation.
The approach applies to maintenance and overhaul settings including rail and marine work. The scope reflects the asset, support functions and requirements of the specific maintenance organization.
Timing depends on the maintenance family, support dependencies, available information and implementation scope. Design, pilot deployment and wider rollout are agreed as separate phases where appropriate.
The equipment or maintenance family, turnaround performance, recurring interruptions, support-shop constraints and any target dates are useful starting points. You do not need a complete data pack to make an initial enquiry.
