From idea to series: the strategic stakes of industrialising a product
Industrialising a product is a critical step in transforming a validated prototype into series production. This process aims to guarantee cost control, constant quality and adherence to time-to-market deadlines, while ensuring long-term profitability.
Contrary to popular belief, this phase goes far beyond mere manufacturing. It involves rigorous planning to align technical choices with industrial constraints, customer expectations and regulatory standards. A poorly anticipated industrialisation exposes the company to unforeseen cost overruns, recurring quality defects or delays compromising competitiveness on the market.
To move from prototype to production, the specifics of mass manufacturing must be integrated from the design stage: choosing suitable materials, optimising processes and selecting reliable industrial partners. This anticipation reduces risks and maximises manufacturing efficiency, avoiding costly adjustments at an advanced stage.
A major challenge, industrialisation determines the longevity of the product. Rigorous execution makes it possible to secure the investment, accelerate market launch and guarantee impeccable product consistency. To avoid the common pitfalls of industrialisation, a structured and forward-looking approach is essential.
Anticipation, the key to success: optimising design for manufacturing (DFM)
Did you know that 90% of a product’s cost is determined at the design phase? This key statistic underlines the crucial importance of a proactive approach from the very start of development. Although the innovation of the prototype is often the main focus, neglecting industrialisation at this stage exposes you to unforeseen costs. This is precisely where optimising design for manufacturing (DFM) must come in.
What is Design for Manufacturing (DFM)?
Design for Manufacturing (DFM) is a methodology that integrates manufacturing constraints from the design stage. Its objective: to facilitate production, reduce costs, improve quality and accelerate market launch. This collaborative process involves design teams, manufacturers, suppliers and quality specialists.
It is applied after the prototype has been finalised, before tooling is produced, to avoid costly modifications. By anticipating these principles, you secure your investment and optimise the bill of materials (BOM) for a successful industrialisation. It is a key step in transforming a prototype into a manufacturable product at scale, as demonstrated by the automotive industry (simplification of assemblies) or electronics (multifunctional components).
The optimisation levers of DFM
Design for Manufacturing (DFM) acts on several levers to optimise manufacturing quality and reduce production costs :
- Reducing the number of components : Fewer parts reduce the risks of failure, the number of suppliers to manage and the assembly steps. Example: an electronic housing can integrate mechanical and electrical functions in a single element, eliminating fastenings.
- Standardization : Using standard components simplifies the supply chain and reduces costs and lead times. Common metric screws or universal connectors are preferable to custom-made parts.
- Choice of materials : Selecting materials suited to the manufacturing techniques optimises costs, output rate and robustness. Example: an injectable plastic with additives strengthening its solidity avoids costly secondary treatments.
- Simplifying assembly : Designing for rapid assembly with few tools makes it possible toeliminate waste (Muda). Integrated snap-fits or clips reduce assembly time and errors.
These levers, when applied together, transform a complex design into a manufacturable, profitable and high-quality product. Their early integration ensures that the bill of materials (or BOM) is optimised from the outset for efficient production, with benefits for lead times and margins.
The sequential stages of industrialisation: from pre-series to mass production
Step 1: Sourcing and selecting industrial partners
The sourcing determines the longevity of the project. Criteria include technical expertise, quality certifications (e.g. ISO 9001), financial solidity and CSR standards. A medical manufacturer favours a partner certified to ISO 13485 to comply with strict regulations and avoid costly recalls due to non-conformities.
Contracting incorporates clauses on traceability, late-delivery penalties and quality audits. An Asian subcontractor for electronic components must meet tolerances of 0.01 mm. Negligence exposes the company to shortages or costly recalls, such as a soldering error on 10% of the circuits, resulting in losses of €200,000.
Step 2: Developing tooling and defining processes
Specific tooling (moulds, jigs) dictates the final quality. An injection mould for a plastic housing requires shrinkage tests and temperature adjustments. A car manufacturer invests €80,000 in a steel mould to produce 500,000 parts/year, i.e. a unit cost of less than €0.20 after amortisation over 5 years.
The industrial layout uses digital tools such as CAD/CAE simulation to optimise the arrangement of machines. Soft tooling (3D-printed or silicone) validates the functional form, while hard tooling in stainless steel is used for final production, avoiding deformation at high temperatures. For example, an aluminium mould for an electronic housing allows rapid cooling, reducing the cycle from 15 to 10 seconds.
Step 3: Validation through pre-series (EVT / DVT / PVT)
Pre-series (EVT, DVT, PVT) avoid costly errors in series production. For a wireless audio headset, the EVT tests the electronic components on 30 units, the DVT validates 1,000 impacts for solidity, and the PVT measures the scrap rate (2% max) and the output rate (e.g. 10 units/hour). A defect not detected at PVT can generate a scrap rate of 15%, multiplying costs fivefold.
| Phase | Acronym | Objectif principal | Key questions |
|---|---|---|---|
| Engineering Verification Testing | EVT | Validate the first parts produced from series tooling. | Have we built the product right? |
| Design Verification Testing | DVT | Verify the performance and reliability of the assembled product. | Have we built the right product? |
| Production Verification Testing | PVT | Validate production at the target output rate and cost. | Can we mass-produce the right product? |
The PVT includes accelerated tests, such as 1,000 thermal cycles (-20°C to 80°C) for an industrial sensor. Hard tooling (aluminium moulds) is frozen, as any subsequent modification would incur additional costs of 15 to 30%. According to a McKinsey study, 30% of series defects stem from insufficient validation of tooling, leading to recalls or production stoppages.
The ramp-up after PVT incorporates progressive automation. A drone manufacturer can go from 20 to 100 units/day in 3 months thanks to collaborative robots (cobots), reducing quality variations between batches for a consistency of 99.5%.
Securing your innovation: intellectual property and control of tooling
Tooling ownership: a strategic point of vigilance
Tooling, such as moulds or precision tools, constitutes critical assets, representing up to 40% of the initial investment in sectors such as automotive or aerospace. Their legal ownership, often neglected, can generate costly disputes.
Two models stand in opposition in subcontracting: partner ownership (immediate access but dependence) and client ownership (flexibility but complex logistics management). The absence of a clear clause has already forced companies to buy back their moulds from their subcontractors, causing production delays of several weeks.
The manufacturing contract must therefore specify tool ownership, maintenance costs and the conditions for their return. These provisions prevent litigation and ensure industrial continuity, particularly in the event of a partnership break-up or repatriation of production.
Protecting your intellectual property (IP) in a subcontracting context
In an international context, intellectual property (IP) is threatened by transfers of technical data. A WIPO study indicates that 30% of disputes between clients and suppliers concern emerging creations. Without a framework, a subcontractor can patent an improvement, forcing the client to pay royalties for its own process.
- Non-disclosure agreements (NDA) : Define the information covered (3D drawings, formulas, test data), the duration of confidentiality (e.g. 5 years after termination) and the penalties in the event of a breach.
- Clear manufacturing contracts : Specify the rights to exploit the IP, the territoriality of licences (e.g. exclusive manufacturing in Europe) and non-compete restrictions.
- Patents and designs & models : Register protections in key jurisdictions (e.g. China, United States, EU) to prevent counterfeiting. A technology company thus avoided being copied in Asia by registering its designs a year before launch.
For multinationals, divergent rules on technical improvements can block exports. The contract must therefore provide for the systematic assignment of these rights to the client, with an obligation for the subcontractor to sign the necessary deeds. This avoids unforeseen royalty claims and secures the global value chain.
Guaranteeing excellence: quality, compliance and continuous improvement
Putting in place a quality control plan
Industrialising a product requires rigorous standardisation of quality. The quality control plan defines verification points at each key stage: receipt of components, production, finished product. It sets test frequencies, measurement tools and acceptance/rejection criteria.
This plan makes it possible to anticipate drifts before they generate non-conforming batches. For example, systematically measuring dimensional tolerances from the assembly phase onwards avoids costly industrial scrap. Operational teams are trained to apply these protocols with calibrated equipment.
Ensuring compliance and certifications
Legal compliance is non-negotiable. In Europe, CE marking attests to compliance with standards on safety, the environment and health. Tests must be carried out on series-production samples, often in the DVT (Design Verification Testing) or PVT (Production Validation Testing) phase, to validate reproducibility.
International industrial partners, such as NRTL laboratories in the United States, verify compliance with local standards. These certifications, such as those of AFNOR in France, strengthen customer confidence and open up regulated markets. They include regular audits to maintain the validity of the certifications.
Steering production through continuous improvement
The series production phase is not static. Field feedback, such as manufacturing defects or after-sales returns, must be analysed to optimise processes. The PDCA (Plan-Do-Check-Act) method is a pillar of continuous improvement in industry.
Lean Management, by eliminating waste (Muda), unevenness (Mura) and overburden (Muri), maximises efficiency. For example, a factory using Six Sigma reduces defects to fewer than 3.4 per million units. Automating quality indicators through AI speeds up the detection of anomalies.
- Plan: Identify quality deviations.
- Do: Test adjustments on a pilot batch.
- Check: Measure the impact of the modifications.
- Act: Deploy the improvements or correct.
To go further, the PDCA (Plan-Do-Check-Act) method is a pillar of continuous improvement.
