]]> Some importers think of quality control as something that happens near the end of production. The goods are made, an inspector checks them, and the buyer hopes that any serious problems are found before shipment.

However, that approach is risky.

A final inspection can detect defects, but it usually cannot explain all the upstream decisions that created them. By that point, the product requirements may be vague, suppliers may already be selected, components may already be approved, tooling may already be made, and the production process may already be running.

That is why QC needs to be built into the NPI process.

Before mass production starts, buyers and manufacturers should define clear product requirements, qualify suppliers and components, plan incoming and in-process controls, prepare inspection and testing methods, review process risks, and use pilot runs to prove that the QC system actually works.

In this episode, Adrian and Renaud discuss the quality control processes that should be implemented during NPI and why preventing defects early is usually far cheaper than finding them later.

]]> In the previous episode, we looked at what changes between prototype and production. In this second part, Adrian and Paul focus on three common failure patterns that often appear after prototype approval:

  1. A component is swapped for a cheaper or more available alternative.
  2. Firmware is cleaned up before production release.
  3. Production is transferred from a prototype shop to a mass production factory.

Each change may look reasonable on its own. The new component may appear equivalent on the datasheet. The firmware update may seem like routine tidying. The new factory may appear capable of making the same product. But each one can change the configuration that was originally validated.

That is why a working prototype is not the same thing as a production-ready product.

In this episode, you’ll learn why component changes, firmware changes, factory transfers, tolerance shifts, and process differences need to be controlled before production starts. We also cover practical safeguards, including configuration control, phase gates, production-representative builds, factory audits, pilot runs, and validation tracking.

]]> A prototype that works is encouraging. It proves that the concept is technically possible, gives the team something tangible to test, and often unlocks the next stage of investment or customer approval. But it does not prove that the product is ready for production.

This is where many hardware projects run into trouble. The prototype is approved, the team moves ahead, tooling starts, suppliers are lined up, and everyone assumes the production units will behave in the same way. Then the first batch arrives, and unexpected failures appear.

The reason is often simple: the prototype and the production unit are not really the same thing.

In this episode of China Manufacturing Decoded, Adrian and Paul Adams, head of new product development, discuss part one of this problem: what actually changes between prototype and production, and why those changes can lead to production failures if they are not controlled. Next week, we’ll continue the discussion by looking at common real-world failure patterns, including component swaps, firmware tidy-ups, factory transfers, and how a structured NPI process helps close the gap.

]]> It’s easy to focus on the unit price quoted by a supplier. After all, if the product cannot be made at the right cost, the project may not be commercially viable. However, there is another cost category that is often underestimated, especially when developing a new or customized product: non-recurring engineering (NRE) costs.

NRE costs are one-time costs needed before production can really begin. They may include product design, engineering, prototyping, tooling, supplier sourcing, testing, certification, fixtures, and production setup.

In this episode of China Manufacturing Decoded, we discuss what NRE costs are, where they usually appear, why they often grow, and what importers should do to avoid unpleasant surprises before launching production.

]]> Many hardware product development projects do not fail because the idea is bad, the team is lazy, or the manufacturer is incapable. They fail because the project starts with too much missing information.

At first, this may not seem serious. The team has a concept. There may be sketches, a rough design, some target features, and a budget. Everyone wants to move quickly into design, prototyping, tooling, and production.

But when key details are missing, people start filling the gaps with assumptions.

One person assumes the product will use a certain material. Someone else assumes a component is available. Another assumes that the target market requires only one set of certifications. The engineer assumes a certain tolerance is acceptable. The buyer assumes the production cost will fit the business model.

Before long, the project is not built on confirmed information. It is built on a stack of assumptions.

And that is where many hardware projects stall.

In this episode, we look at why product development projects often fail to get moving, why a Product Requirements Document is so important, what information should be clarified before development starts, and how companies can avoid wasting weeks or months on work that later needs to be undone.

]]> We’ve seen some people treat a product launch as the end of the development process. In reality, it’s just the beginning.

Once a product reaches real users, a new phase begins: unexpected issues arise, assumptions are challenged, and the way customers actually use the product often differs from what was planned.

This is especially true for innovative or complex products. No matter how much testing is done during development, some risks only become visible after launch, when the product is used in real-world conditions, at scale.

In this article, we’ll look at why trying to perfect a product before launch can backfire, and how a more iterative approach, launching a solid Version 1.0, then improving based on real feedback, can reduce risk and lead to better long-term results.

Not necessarily ignored, but rushed, incomplete, or misunderstood. Needless to say, this is the source of many risks and problems in a manufacturing project!

But if it’s so important, just WHAT is the NPI process? In this episode of Sofeast’s podcast, we revisit our most popular episode on the NPI process to show how crucial it is for your project.

They focus on the bill of materials (BOM), get a supplier quote, and assume they have a clear picture. But once the project moves forward, additional costs start piling up: tooling, engineering work, logistics, certification, and more.

In some cases, these overlooked costs can significantly reduce margins or even make the product impossible to manufacture!

Read and listen as we explain how product costing really works in practice. Based on insights from Paul Adams, Sofeast’s head of NPD, we’ll walk through the main cost components, highlight common mistakes, and show how a design-to-cost approach can help you stay in control from the early stages of development.

By then, the design is finished, suppliers are selected, and production may already be underway. If something fails, fixing it can mean redesigning the product, changing components, or delaying shipments; sometimes all three!

Product compliance is not just about getting a certificate or adding a CE or FCC mark. It involves making sure the product meets safety, chemical, electrical, and regulatory requirements in the markets where it will be sold.

In this episode, we go over what product compliance really involves, why so many companies get it wrong, and what should be done earlier in the process to avoid costly surprises.

]]> Some companies realize their developed product is too expensive and ask,
“How can we reduce the cost?”
But in most cases, that’s the wrong question, and it comes too late.
By the time you reach that stage, the product’s cost structure has already been largely defined by earlier design decisions: the components selected, the product architecture, and how it needs to be manufactured and assembled.
Trying to reduce cost at that point often leads to compromises, redesigns, or pressure on suppliers, none of which are reliable ways to build a sustainable product.
A more effective approach is to address cost from the beginning, by defining a realistic target and designing the product to meet it.
Join us as we explore why products become too expensive to manufacture, the most common mistakes teams make, and how to control cost early through better design and development decisions.
