Every inventor dreams of the moment their idea, born from a spark of inspiration, becomes a tangible, marketable product. Yet, the journey from a prototype to mass manufacturing is a complex process that can seem daunting.
This article will guide you through the process and shed light on key milestones, providing a roadmap to navigate this crucial phase of product development.
Understanding The Scaling Process
What is Scaling in Manufacturing?
Scaling in manufacturing refers to the process of transitioning from a limited production run (prototype) to mass production. It involves setting up large-scale manufacturing operations that can produce high volumes of your product efficiently and cost-effectively.
Why is Scaling Important?
Scaling is a crucial phase in product development because it’s the stage where your product goes from being a concept to a reality. It’s where you start to generate significant revenue and where you begin to realize your invention’s full market potential.
Understanding the challenges and process of scaling is equally important for inventors looking at licensing their inventions. This knowledge allows inventors to present a more realistic and compelling proposition to potential licensees, as they can demonstrate a thorough understanding of what it takes to bring a product to market at scale. It also allows inventors to design their products with manufacturing in mind from the start, potentially reducing future hurdles during the scaling process.
Understanding the scaling process can also help inventors anticipate and navigate the many risks and barriers associated with scaling. These may include issues related to production costs, quality control, regulatory compliance, and supply chain management. By considering these factors in the early stages of product design and development, inventors can strategically design and plan their products to mitigate these risks.
Navigating the Scaling Journey: From Prototype to Production
LLWL: Looks-Like, Works-Like Prototype
The first milestone in scaling your product is creating a Looks-Like, Works-Like (LLWL) prototype. This is a prototype that closely resembles the final product in both design and functionality. The LLWL prototype allows you to test and refine the product design and functionality before moving on to the manufacturing stages. By ensuring the prototype both looks and works like the final product, you are better prepared to identify and address potential issues early in the process, reducing costly changes during the manufacturing stages.

EVT: Engineering Verification Test
The Engineering Verification Test (EVT) is the next milestone in the scaling process. During EVT, a larger batch of your product is produced using low-volume manufacturing techniques, and rigorous testing is conducted to verify that the product meets all the defined engineering specifications.
Injection molding, for example, may be performed using soft tooling – a more cost-effective solution suitable for low-volume production. Electronics may be assembled on smaller production lines or even partially by hand. This approach allows for flexibility and adjustments in the product design and manufacturing process without the substantial investment required for full-scale production.
The testing at this stage is comprehensive and meant to ensure that the product will perform as expected when mass-produced. The types of tests performed during EVT typically depend on the nature of the product, but they often include:
- Functional Testing: This verifies that the product functions as intended. All the features and functionalities of the product are tested to ensure they work correctly.
- Durability Testing: This assesses the product’s longevity and reliability under normal usage conditions. It can include stress tests, fatigue tests, and other types of wear-and-tear testing.
- Environmental Testing: This evaluates how the product performs under different environmental conditions, such as varying temperatures, humidity levels, and atmospheric pressures.
- Safety Pre-compliance Testing: This ensures the product meets all safety regulations and standards. It can include tests for electrical safety, fire safety, mechanical safety, and more, depending on the nature of the product.
- Regulatory Pre-compliance Testing: This verifies that the product complies with all relevant regulatory standards. It can include tests related to emissions, energy efficiency, material restrictions, and more.
These tests may be preliminary verifications if the manufacturing process or materials change as the volume increases. Preliminary testing prevents wasting money on expensive tooling and an inventory of bad products.
By the end of the EVT phase, you should have a high degree of confidence in the design and functionality of your product. Any issues or improvements identified during this stage should be addressed before moving on to the Design Verification Test (DVT) stage.
Quantity: 20-50 units
DVT: Design Verification Test
Once the EVT stage has been successfully completed, you move on to the Design Verification Test (DVT). While EVT focuses primarily on the engineering and functionality aspects of your product, DVT is where the focus shifts to the product’s design and manufacturability at scale.
During DVT, your product undergoes further testing to verify the product design and ensure it can be manufactured at scale. This includes verifying that all components fit together correctly, that the product meets all safety and regulatory requirements, and that the product can be produced efficiently at high volumes.
The types of tests performed during DVT may include:
- Manufacturability Testing: These tests assess whether the product can be produced efficiently and consistently on a larger scale. This might involve testing assembly processes, evaluating the ease of access for repairs, and ensuring that the product can be manufactured within acceptable time and cost parameters.
- Compliance Testing: At this stage, it’s crucial to verify that your product meets all relevant regulatory and industry standards. This can include standards related to materials, safety, emissions, and more. Passing these tests is often a prerequisite for selling your product in many markets.
- Usability Testing: This is where you assess the product’s design from the user’s perspective. It might involve ergonomic assessments, user interface evaluations, and user experience studies.
- Aesthetics and Finish Testing: This involves evaluating the product’s physical appearance and tactile qualities. This could involve testing the durability of the product’s finish, color consistency, and other aesthetic features.
It’s also important to note that units produced during the DVT phase are often used for gathering stakeholder feedback. This can include feedback from potential customers, partners, or investors. This feedback can provide valuable insights into how your product is likely to be received in the market and can help identify any additional improvements that might be needed before proceeding to full-scale production.
By the end of the DVT phase, you should have a product that not only functions as intended but is also ready to be produced at scale, meets all regulatory requirements, and is designed in a way that meets the needs and expectations of your target customers.
Quantity: 100-250 units
PVT: Production Verification Test
The final phase before full-scale production is the Production Verification Test (PVT). This stage differs from DVT in that while DVT is concerned with the product’s design and regulatory compliance, PVT focuses on the readiness of the production line, packaging, logistics, and quality control processes.
In the PVT stage, all manufacturing documentation should be finalized and verified. This includes Quality Control (QC) and Quality Assurance (QA) guidelines, which ensure consistent quality in every unit produced. Detailed checks are made to ensure that the manufacturing line is fully prepared for mass production and that all workers are adequately trained.
Packaging also comes under scrutiny during the PVT stage. This involves verifying everything from the retail box design to the master carton, palletization instructions, and more. Each packaging element is tested for durability, usability, and compliance with regulatory standards. The goal is to ensure that the product and its packaging can withstand the rigors of shipping, warehousing, and retail display, while also providing an appealing and informative presentation to the end customer.
Logistics and warehousing information should also be verified during the PVT phase. This includes confirming shipping schedules, warehousing arrangements, and inventory management processes. It’s crucial to ensure all logistical elements are in place and ready to handle the product at scale.
At this point, the first PVT batch of products could be shipped to a third-party logistics provider (3PL), or the entrepreneur may choose to fulfill a portion of the first PVT batch. This allows for real-world testing of the entire supply chain and fulfillment process, providing a final opportunity to identify and address any potential issues before full-scale production begins.
By the end of the PVT phase, you should be confident that your product, packaging, manufacturing line, and logistics are ready for full-scale production and that you are prepared to deliver a high-quality product consistently to your customers.

Overcoming Common Scaling Challenges
Scaling a product for mass manufacturing presents several challenges. Here’s how to overcome some common ones:
Managing Production Costs
Managing production costs is on of the most common challenges when scaling a product. As you scale, you should aim to reduce the cost per unit by negotiating better prices with suppliers, improving production efficiency, and optimizing logistics and distribution.
Tip 1: Design for Manufacturability (DFM)
Design for Manufacturability (DFM) is a concept that involves designing your product in a way that makes it easy and cost-effective to manufacture. This can involve selecting affordable and readily available materials, simplifying the design to minimize the number of parts or complex assemblies, and considering how the design will impact the ease and speed of the manufacturing process. By thinking about manufacturability from the early stages of design, you can often reduce production costs significantly.
Tip 2: Leverage Economies of Scale
Economies of scale refer to the cost advantage that comes with increased production levels. The more units of a product you produce, the lower the cost per unit typically becomes. This is because many costs associated with manufacturing (like machinery setup or tooling costs) are spread out over a larger number of units. Therefore, if feasible, planning for larger production runs can often help reduce your per-unit costs.
Tip 3: Regularly Review and Negotiate with Suppliers
The costs of materials and components can fluctuate over time due to market demand, changes in commodity prices, and supplier pricing strategies. Therefore, it’s important to regularly review your supply chain costs and negotiate with suppliers to ensure you’re getting the best possible pricing. Building good relationships with suppliers and exploring long-term contracts can often lead to cost savings.
Ensuring Quality Control
Ensuring quality control is a vital aspect of product development and manufacturing, especially when working with a contract manufacturing partner. Here are three tips:
Tip 1: Rigorous Selection Process for Manufacturing Partners
Before you even start manufacturing, selecting a reliable and high-quality manufacturing partner is critical. Look for partners with a proven track record in your industry and ask for references or case studies. Conduct an on-site visit, if possible, or request a virtual tour. Pay attention to their quality control processes, certifications, and their facilities’ overall cleanliness and organization.
Tip 2: Establish Clear Quality Standards and Expectations
Once you’ve selected a manufacturing partner, it’s important to establish clear quality standards and expectations. This includes detailed specifications for each product component, assembly instructions, and acceptable quality levels (AQLs). Make sure these standards are clearly communicated and agreed upon with your manufacturing partner.
Tip 3: Consider Third-Party Quality Control Services
Especially for first-time inventors or small businesses, managing quality control with a remote manufacturing partner can be challenging. In such cases, consider hiring a third-party quality control service. These companies specialize in product inspection and quality assurance and can serve as your eyes and ears on the ground. They can conduct pre-production inspections, in-process quality checks, and final product inspections, ensuring that the product meets your quality standards before it leaves the factory.
Remember, quality control is not a one-time process but a continuous effort. Regular reviews and audits of the quality control process are necessary to ensure consistent product quality.
Navigating Regulatory Compliance
Regulatory compliance is a crucial aspect of bringing a product to market. You cannot license a product if the idea cannot meet compliance. Some product ideas are more expensive to get certified than others. Here are three tips to help navigate this complex area:
Tip 1: Involve UL Early in the Process
Underwriters Laboratories (UL) is a global safety certification company that tests products for compliance with specific safety standards. Getting UL certification can be a lengthy process, so it’s important to involve them early in your product development process. By doing so, you can identify potential compliance issues early and design your product with these standards in mind rather than making costly modifications later on.
Tip 2: Partner with an Expert
Navigating the landscape of regulatory compliance can be complex, especially for new inventors or small businesses. Therefore, it can be beneficial to partner with an expert who has experience with bringing products to market at scale. This could be a consultant, a compliance officer, or a mentor who has gone through the process before. They can provide invaluable advice, help you avoid common pitfalls, and guide you through the process more efficiently.
Tip 3: Understand Your Target Markets
Different countries and regions have different regulatory standards and requirements. Therefore, it’s important to understand the specific requirements of your target markets. This could involve researching local regulations, consulting with legal experts, or contacting relevant regulatory bodies. By understanding these requirements upfront, you can ensure your product is designed and manufactured to meet all necessary compliance standards.
Remember, non-compliance can lead to product recalls, legal issues, and damage to your brand reputation, so it’s crucial to take the time to understand and meet all relevant regulatory requirements.
Conclusion
Scaling a product from prototype to mass manufacturing is a complex journey. Yet, with the right understanding and preparation, it’s a journey that can lead to remarkable rewards. As Stanford’s Doerr School of Sustainability highlights, thinking about scale from the beginning and understanding the risks and barriers associated with scaling can help develop strategies to overcome these barriers and accelerate the scale-up of solutions.
Challenges such as identifying cost-reduction pathways, managing supply chain risks, and navigating policy barriers require careful consideration and strategic planning (link). This process might be time-consuming and costly, but the rewards of a successfully scaled product are worth the effort.
