OEM build rate, defense programs, and the broader value chain. Long-cycle, certification-bound operations where the cost of an idle aircraft is measured in millions per day.
Aerospace and defence runs on long-cycle production, certification-bound trades, and a value chain where every interface is regulated. Build rate at the OEM, takt at the line, program delivery at the defense prime, AOG reduction at the MRO, and tier-one supply discipline against the schedule. Proudfoot has installed at depth in aerospace and defence at OEM lines, on defense programs, across MRO operations, and through the tier-one supply chain. The discipline holds across the hangar, the line, and the program.

Where the value lives, and where it leaks.
Aerospace and defence is one of the most complex operational environments in heavy industry. Every hour an aircraft sits on the ground costs money, and every missed turnaround ripples across fleet schedules, customer commitments, and the operator's revenue. Every improvement has to happen without a single compromise on safety or quality, against a regulatory regime that touches every certified-trade hand on the airframe and every certified part on the bill of materials. The OEM builds to a multi-month or multi-year cycle; the defense prime delivers to a program schedule with public and contractual scrutiny; the MRO turns the aircraft against minutes that translate into AOG dollars; the tier-one supplier holds the line on the schedule that feeds the build rate above. Variability at any one of those interfaces compounds across the value chain.
The cost of error in aerospace and defence is measured in three currencies that compound on every shift. Schedule and program attainment, where build rate at the OEM, takt at the line, and the program schedule at the defense prime all run against fixed delivery commitments and political or commercial scrutiny. Asset hours, where an aircraft on the ground at an MRO, a delivery slip on an OEM build slot, or an unplanned removal at the tier-one supplier all read directly to the operator's revenue or the prime's reputation. Certification and quality, where every frontline decision is bounded by the airworthiness standard and the customer specification, and where rework, escape, or a missed sign-off costs more than the build itself. The three currencies are connected: a missed frontline sequence costs schedule, a poorly executed turnaround costs asset hours, and a rework on a certified component costs certification time and trust.
And it is on the frontline that the work actually gets done: on the assembly station, in the engine shop, in the bay, and on the runways and ramps where the ground crew turns the aircraft. Proudfoot installs at that level, working brown papers reviewed and critiqued on the shop floor by the people who run the operation, because in a certification-bound environment the standard holds when the supervisor and the certified trade own it. The change is theirs after we leave, and that is why it sticks.
Where the discipline lands.
OEM aerospace
Commercial single-aisle and twin-aisle assembly, regional aircraft, and business jet operations. Build rate, takt at the line, mixed-model station discipline, certified-trade productivity, supplier-fed assembly cadence, and the supervisory rhythm that holds the line against the programme.
Defence aerospace
Platforms, mission systems, and the integrated programme delivery that surrounds them. Programme schedule attainment, contractor coordination, certified-trade productivity, integration cadence, and the operating discipline that lifts the on-time programme promise rate against contractual scrutiny.
Space systems
Launch services, satellite and payload integration, and the production cadence that runs underneath. Programme schedule attainment, integration takt, certified-trade productivity at low-volume high-complexity build, and the engineering-to-build interface where production cadence either holds or slips.
MRO operations within aerospace
Heavy base maintenance, engine overhaul, line maintenance, and ground operations. Turnaround time against AOG cost, hangar density, certified-trade productivity, planner-supervisor handover, and the bay-level operating cadence that runs the turnaround.
Aerospace supply chain
Tier-one and tier-two supply, propulsion and structures suppliers, MRO services partnerships, and the cross-tier programme management that keeps build rate sustainable. Schedule attainment, first-pass yield against certified specification, supplier-development discipline, and the cross-organisational cadence between the OEM and the tier-one.
Four capabilities aerospace and defence COOs recognize.
Improve Productivity
Frontline supervision in long-cycle production. Standard work at the assembly station, takt-time discipline at the line, certified-trade productivity at the bay, and the bay-leader cadence that connects the planner, the mechanic, the inspector, and the supervisor. Productivity in aerospace and defence is a behavior question first, a planning question second, and a tooling question third, bounded by certification and held by trained supervisors after handover.
Improve Asset Utilization
MRO turnaround time, fleet uptime, hangar density, AOG reduction, and the planned-versus-unplanned discipline that runs underneath. Each hour an aircraft sits on the ground is measurable cost, and each compressed turnaround is sustainable only when the operating system, the planner, the supervisor, and the certified trade all hold to the same standard. Reliability-centred maintenance, planned shutdown discipline, and bay-level cadence carry the long tail of the value.
Optimize CAPEX
Aerospace and defence program execution at scale. OEM line installation and ramp-up, defense program delivery, brownfield modernisation, and the contractor coordination that surrounds them. The work installs the same operating discipline on a program as on a frontline: short interval control, daily and weekly cadence, frontline supervision, contractor coordination, and a measured base case the program is run against. The on-time program promise rate moves when the operating system holds across the prime, the supplier, and the integrator.
Optimize Workforce
Skilled-labor planning against the build rate, certified-trade scheduling, span of control on the frontline, and the multi-skilling discipline that lets the operation respond to demand without losing the certified specification. Aerospace and defence workforce design is constrained by certification, regulatory training requirements, union agreement, and shift patterns built around long-cycle production. The operating discipline holds inside those constraints; the right certified trade, at the right station, on the right shift, with the right backup.
Production. Asset Management. Construction.
Production
The OEM line, the assembly station, the frontline, the daily operating rhythm against the build rate. Takt, station discipline, first-pass yield against certified specification, schedule attainment, frontline supervision.
Asset Management
MRO turnaround discipline at the heart, plus fleet reliability, planned shutdown design, planning and scheduling, certified-trade rota, and the supervisory cadence that holds the bay intact. The right work, on the right asset, at the right interval, executed to the certified standard.
Construction
OEM line installation and ramp-up, defense program delivery, brownfield modernisation, contractor coordination, and capital project recovery. The same operating discipline on a program as on a frontline.
The method behind the work.
The Proudfoot System runs the engagement, end to end across five phases and 86 steps, sized to the build rate and the program milestones in front of you. Three components carry the aerospace and defence work: short interval control on the build line, the management operating system that holds takt, and the supervisor behaviors that keep first-pass quality on a regulated part.
The Proudfoot MOS (the 6+4 Element Framework) is the operating discipline that makes the capabilities deliverable. The discipline has been installed at depth across the aerospace and defence value chain: at OEM commercial assembly lines in Europe and North America, on defense aerospace programs across the United Kingdom, France, and the United States, at heavy-base and line MRO operations across Europe, Asia-Pacific, and the Americas, on aerospace tier-one supply across France, Spain, and the United States, and at airport and ground-operations sites across Europe and North America. It has held in the assembly bay and on the engine line, in the hangar and at the gate, on the frontline and at the supplier interface.
The 8 Active Management Behaviours (8AMBs) are the supervisory behaviors that make the operating discipline stick. Observable on the assembly station, the frontline, the engine shop, the start-of-shift huddle, the planner-supervisor handover, the certified-inspector sign-off, and the program-manager review. Codified, coachable, repeatable. The 8AMBs are how the supervisor cohort runs the operation after Proudfoot leaves, and how a multi-site MRO network or an OEM line stays coherent across shifts and sites without a central control tower.
Aerial Mapping is the structured executive interview discipline that surfaces the value at the start of the engagement. In aerospace and defence the executive cohort spans the head of program, the head of operations, the head of production, the head of engineering and quality, the head of supply chain, the head of MRO and customer support, the head of HSE and certification, the head of HR for the certified trades, and on multi-site networks the regional or program operations leader. The technique surfaces the variance between the strategic case and the operating reality across all of them.
