The electronics manufacturing industry is riding wave after wave of disruption. A forecast that looked healthy 90 days ago can be obsolete by Friday. A part you’ve used for five years suddenly goes EOL. Logistics lanes flex, compliance rules tighten, macroeconomics and geopolitics shift, and launch windows don’t move.
Many OEMs still fight this with the same old approach of “squeeze unit price, lock the plan, hope the world behaves.” It rarely does.
Cost matters deeply, but in a volatile market, the winners are optimised for response, not just efficiency. They design for options, not for one perfect path. They treat change as a capability, not an exception. This is where a strong EMS partner helps OEMs swap fragility for resilience without inflating total cost to serve.
Volatility is the new normal
From ongoing semiconductor shortages and shipping delays to inflationary pressures and geopolitically driven trade restrictions, volatility has gone from a temporary inconvenience to a persistent state.
For OEMs, this translates into more than just operational headaches. Extended lead times, unpredictable costs, delayed new product introductions, and quality risks are now regular challenges.
What does volatility look like for OEMs?
Volatility manifests across every stage of the OEM value chain as:
- Lead-time variability: Component lead times can swing from 8 to 52 weeks without warning.
- Forecasting mismatches: Demand signals are often outdated by the time procurement reacts.
- Expedites and firefighting: Teams scramble to re-source or ship by air, driving up costs.
- Inventory imbalance: Simultaneous excess and shortages, draining working capital.
- Delayed NPIs: Launches slip due to part unavailability or requalification delays.
- Strained supplier relationships: Increased churn, renegotiations, and mistrust.
What’s causing this?
Several macro and structural forces are converging, generating this volatility.
One major contributor is a persistently fragile global supply chain. An overdependence on single-source suppliers or manufacturing concentrated in distant geographical regions amplifies the risk and impact of disruption, leading to sudden shortages and unpredictable delays.
This is compounded by the inherent instability in logistics, where unstable freight costs, often driven by issues such as port congestion and capacity shortfalls, make planning and cost forecasting particularly challenging.
In addition to supply chain pressures, the industry must contend with the growing pace of technological advancement and subsequent technology churn. Rapid obsolescence is a constant factor that compresses product lifecycles and tightens the critical window from product design to full-scale production.
Simultaneously, OEMs are navigating an increasingly complex landscape of regulatory and ESG pressures. Shifting compliance mandates along with rising expectations for corporate sustainability necessitate substantial changes in sourcing, design, and manufacturing processes, adding layers of complexity to operations.
Further exacerbating these challenges is a structural issue related to manufacturing capacity. Key suppliers often face capacity constraints, a situation that forces them to prioritise their output. In this environment, these critical partners naturally favour high-volume clients or those deemed strategically important.
The business impact beyond operations
The downstream effects of this volatility include:
- Revenue risk: Missed shipments and product delays affect top-line growth.
- Eroding margins: Expediting, reworks, and scrapping inflate costs.
- Time-to-market delays: Slow ramps limit competitive edge and window of opportunity.
- Customer dissatisfaction: Broken SLAs damage trust and lead to churn.
- Increased board-level scrutiny: Leaders face pressure to de-risk supply and improve agility.
Each of these disruptors chips away at profitability, customer relationships, and growth potential. OEMs must build structural resilience into their operations to navigate this uncertainty, not just survive it.
A capable EMS partner can play a decisive role in strengthening operational resilience. But success demands robust strategies, clear execution, and the right partnerships.
OEM strategies for navigating volatility
1. Demand sensing and scenario planning
Traditional forecasting models often fail under volatile market conditions. OEMs must move beyond static predictions and adopt demand sensing techniques that draw on real-time data sources, including point-of-sale and distributor stock movements. This allows them to detect shifts earlier and respond faster.
By combining this with scenario planning—modelling best, worst, and likely case demand patterns—supply chain and operations teams can align inventory and capacity plans with changing realities.
KPIs to watch include forecast accuracy, plan adherence, and order cycle responsiveness.
2. Design for supply: DfX and BoM risk mitigation
Design decisions made early in the product development cycle can either create resilience or embed risk. Design for supply means incorporating supply chain awareness into engineering choices and specifying components with multiple sources, avoiding known bottlenecks, and flagging parts at risk of obsolescence or long lead times. Working with EMS partners during design helps validate alternatives and mitigate risk before it's baked in.
Metrics such as BoM risk index, number of approved alternates, and NPI delay frequency should be tracked to ensure this strategy is delivering.
3. Supplier diversification and dual sourcing
Single-supplier dependencies are a known Achilles' heel in electronics manufacturing. Diversifying suppliers across regions and technologies can reduce exposure to disruption, but must be done with a structured approach. That includes identifying sole-source parts, qualifying alternate suppliers, and ensuring second sources meet quality and scale requirements. Procurement teams must also develop risk-scoring models to prioritise dual-sourcing efforts.
The percentage of dual-sourced parts and average lead time variability are key indicators of maturity here.
4. Regionalisation and multi-site manufacturing
Geopolitical tensions, trade tariffs, and rising freight costs are making regionalisation more attractive. OEMs can improve resilience by deploying multi-site manufacturing models, splitting production between, for example, Malaysia and the Czech Republic, while ensuring both locations adhere to mirrored quality and process controls. This also allows for late-stage postponement, where products are finished closer to the end customer.
Monitoring transit time, landed cost variance, and delivery performance by region helps quantify the benefits of this strategy.
5. Inventory segmentation and strategic buffering
Treating all inventory the same leads to bloated stockpiles in some areas and crippling shortages in others. A more effective strategy segments inventory by risk and impact, applying higher buffer levels or vendor-managed inventory to high-risk parts, while tightening controls elsewhere. This tailored approach helps balance working capital against availability.
KPIs include inventory turns, fill rate, and days on hand for priority components.
6. Lifecycle and obsolescence management
With component lifecycles shortening, proactive lifecycle management is vital. This involves subscribing to product change notifications (PCNs), tracking component status within PLM systems, and triggering redesigns before parts become unavailable. Done well, it prevents last-minute redesigns and end-of-life panic buys.
Track the percentage of EOL parts in current BoMs and the average time from PCN to action to gauge effectiveness.
7. NPI agility and modular platforming
Launching new products quickly is essential, but not at the expense of quality or stability. OEMs can improve NPI velocity through modular designs that reuse validated subsystems and by integrating EMS partners early to support fast prototyping and production readiness. This reduces the effort required for validation and accelerates time to revenue.
Useful KPIs include prototype cycle time, NPI ramp success rate, and engineering change order (ECO) frequency.
8. Factory transfers and strategic outsourcing
Sometimes, in-house operations simply can't scale or flex quickly enough. Strategic outsourcing to an EMS partner can relieve internal pressure, accelerate growth, or support a site closure or product carve-out. However, factory transfer requires a structured approach, including validation, pilot builds, and clear governance.
Partnering with an EMS provider: What good looks like
When volatility is the norm, OEMs must evaluate EMS partners not just for cost or quality, but for capability and alignment.
Capabilities to look for include:
- Early-stage NPI/DFX support
- Component engineering and BoM risk insights
- Global sourcing and logistics coordination
- Rigid quality and compliance processes
- Multi-region footprint with mirrored systems
- Lifecycle services (e.g. obsolescence, after-market)
- Digital tools and dashboards for transparency
Questions to ask when evaluating partners:
- Can they provide audit-ready data and governance cadences?
- Are they proactive with risk mitigation, or reactive?
- Do they have peer-level technical staff and scalable resources?
- What do past factory transfers say about their agility?
