Building a QA system from scratch: what Morpho does before any product ships
TL;DR
- Quality assurance is the system that defines standards and builds checkpoints.
- Quality control is the inspection activity that verifies them at specific points.
- QC without a QA framework catches problems late, when they are expensive to fix.
- Stage 1, DFM review: engineering and supply chain review the design together before tooling, covering tolerances, structural validation, electronics, mold flow, and assembly feasibility.
- Stage 2, BOM qualification via the Component Control Method: every critical component is tested, verified against spec, and sourced from a vetted supplier.
- Stage 3, IPQC gates: inspection points sit inside the production sequence with documented pass/fail criteria.
- Stage 4, pilot run: the first full run on production-intent tooling with production components.
- Stage 5, golden sample approval: one unit passes a comprehensive inspection, gets signed off by the client, receives a unique ID, and is documented and stored as the physical benchmark for the entire run and all reorders.
- Stage 6, pre-shipment inspection: AQL statistical sampling once 80% of the order is produced and packed, plus verification of quantity, packaging, labeling, and destination-market compliance.
You probably already have a product you want to put into the world.
You’ve spent months developing it, and now you’re vetting manufacturers, comparing quotes, and trying to figure out who’s actually going to take it across the finish line.
In the middle of all that, there’s one thing that has to be on your radar before you commit to anyone: quality assurance vs quality control.
Every founder wants to ship fast. Getting the product in hand, launching, and, starting to sell is a real urgency.
But the most strategic decision you’ll make in manufacturing is about building a QA system that maps out problems before the product ever reaches a customer. Because once it’s out in the world, a quality failure costs trust.
Most manufacturing partners describe their quality process in vague terms.
Here’s ours: six stages, applied to every product we build, explained the way we actually run them.
Quality Assurance vs Quality Control
Before we get into the stages, it’s worth saying what a QC and a QA system actually is, because it gets confused with quality control all the time, and the difference matters.
Quality control is an inspection activity. It checks whether a product meets a standard at a specific point.
Quality assurance is the system that defines what those standards are, builds the checkpoints that enforce them, and makes sure problems are caught before they compound. QC is reactive, whereas QA is the architecture that makes QC meaningful.
In simple terms: a QA system is what you build before production begins, defining what your product must be, how it must be made, and what evidence you’ll accept that it was made correctly.
At Morpho, that system runs in six stages:


Each stage has a specific job.
Each one catches something the previous stage can’t. None of them are optional, as you’re going to see below!
Stage by Stage: How Morpho Builds Quality Into Every Product
Stage 1: DFM Review and Quality Standards Definition
We believe a design that looks good must also be buildable.
More than a philosophical position, it’s the most expensive lesson in hardware manufacturing, and founders learn it after the molds are already cut.
Before anything goes to tooling, our engineering and supply chain teams review the design together. Not sequentially, in tandem, because the decisions interact. For instance, a tolerance that works in CAD can create an assembly problem at scale.
A component choice that seems fine on paper can introduce a supply chain risk three months into production. The review catches those things when they’re cheap to fix.
What the DFM review covers at Morpho:
- Tolerance analysis: fit, assembly behavior, material interaction under real conditions
- Structural validation: stress, durability, ergonomic considerations
- Electronics validation: schematics, PCB layouts, firmware integration
- Mold flow analysis for injection-molded parts
- Feasibility of assembly methods and adhesives
- Risk identification: sink marks, warpage, parting lines, surface finish conflicts
Every risk flagged gets resolved before steel is cut. Reports and 3D visualizations go to the client for review, so the founder understand what changed and why before production moves forward.
Stage 2: BOM Qualification via the Component Control Method
The Bill of Material (BOM) is one of the most consequential documents your product will ever have. Who controls it defines the manufacturing relationship you’re actually in.
At Morpho, every critical component is qualified before it reaches the production line. That means tested, verified against spec, and sourced from a vetted supplier.
This is what we call the Component Control Method: breaking every build into its critical parts, finding the right specialist supplier for each one, and bringing them under one managed process.
The deliverables from this stage are two documents that govern the rest of production:
- Pre-MP samples: client-approved physical samples produced before scaling begins. No mass production starts without sign-off.
- QC Standard Document: defines tolerances, inspection methods, and defect categories specific to your product. This isn’t a generic checklist. It’s written for your product, against your specifications.
The BOM itself is transparent, including named suppliers, no generic placeholders, no black boxes that let components get swapped without your knowledge. It’s yours to take if you ever leave.
Stage 3: In-Process Inspection Gates (IPQC)
In-Process Quality Control (IPQC) is where drift gets caught before it becomes a batch problem.
Most defects in manufacturing don’t appear out of nowhere. They develop gradually, like a torque setting that drifts over a shift, a soldering temperature that runs slightly high for two hours, an adhesive application that varies between operators. End-of-line inspection catches drift after hundreds of units are already compromised, IPQC catches it while the line is still moving.
At Morpho, inspection gates are defined at specific points in the production sequence, and each one has documented pass/fail criteria tied directly to the QC Standard Document from Stage 2.
Stage 4: Pilot Run with Defect Rate Tracking
The Pilot Run is a validation gate, that is, the first time the full production process runs on production-intent tooling, with production components and under production conditions.
The distinction matters because a prototype can be hand-built to compensate for process gaps. Mass production can’t. The pilot run is where you find out whether the process works as intended, beyond the design.
At Morpho, every unit from the pilot run is inspected to the full quality specification from the QC Standard Document. Defect rates are tracked, categorized by type, and traced back to their source.
If a defect pattern appears, it gets a root cause, a fix, and a re-run of the affected inspection before production is authorized to scale.
The math here is straightforward: a problem found at the pilot run costs time. The same problem found after 5,000 units have shipped costs time, money, and customer relationships. Finding during this stage is the point.
Stage 5: Pre-Mass Production Golden Sample Approval
Once the pilot run passes, one unit goes through a final, comprehensive inspection against every requirement in the QC Standard Document. That unit becomes the golden sample against which every mass-produced unit will be measured.
The master reference is produced from production tooling, production components, and the production process exactly as it will run at scale. It’s what your product looks, feels, and functions like when the process is running correctly.
We inspect the unit against dimensional tolerances, surface finish specifications, functional requirements, and assembly criteria, while the client reviews and signs off. Both parties are aligned on exactly what “correct” looks like before a single mass-production unit is made.
Once approved, the golden sample is assigned a unique ID, documented with high-resolution photography and dimensional records, and stored.
Stage 6: Pre-Shipment Inspection Against the Golden Standard
When at least 80% of the order is produced and packed, pre-shipment inspection begins. This is the final gate before the product leaves the factory.
Statistical sampling follows Acceptable Quality Level (AQL) methodology, the industry standard for batch inspection, so the sample size reflects the batch size and the agreed defect tolerance.
Beyond the units themselves, we verify quantity, inspect packaging, confirm labeling, and check compliance documentation against the destination market’s requirements.
If the batch fails inspection, it doesn’t ship. Production stops, the root cause gets found, the fix gets made, and the gate runs again. Some partners would call a delay, but is really just the difference between a QA system and a compliance exercise that checks boxes regardless of what’s in them.
What Each Stage Actually Prevents
Here’s exactly what each stage in Morpho’s process is built to catch, and what gets transferred to the founder if that stage is skipped:

Every stage that gets skipped is a gap, and in manufacturing, it always lands on the founder.
Écoute: What Happens When Every Stage Matters
The vacuum tube headphone was considered an engineering impossibility, because it draws too much power and runs too hot.
Every engineer approached about the concept said the same thing: you cannot put a vacuum tube in a headphone.
Early prototypes confirmed the heat and battery risk were serious enough to stop the project.

However, we didn’t the thermal limit as fixed.
Our team re-opened component sourcing and identified the Korg Nutube 6P, a next-generation tube drawing roughly 2% of the power of a conventional vacuum tube, running cool enough to make the concept viable.
From there, the design went through DFM and the Component Control Method, as we sourced critical components separately across vetted supplier and inspected them individually before assembly. The dual-mono architecture, thermal management, power budget, and acoustical integrity were all engineered from scratch.
This is what the manufacturing scope actually looked like:


The outcome: Écoute raised $207,052 on Kickstarter and $284,147 on Indiegogo with the TH1, then $890,704 from 1,203 backers with the TH2, over 2,390 backers across three campaigns.
The TH1 received an Editor’s Choice from Magnetic Magazine and debuted at CES and NAMM.

FAQ
What is the difference between quality assurance vs quality control?
Quality assurance is the system built before and during production, defining standards, validating processes, and structuring checkpoints that prevent defects from occurring in the first place. Quality control is the inspection activity that verifies whether a product meets those standards at specific moments. QA is proactive; QC enforces it. A manufacturing process that runs QC without a QA framework is doing final inspections without any architecture behind them, catching problems late, when they’re expensive.
What is a QA system in manufacturing?
A QA system in manufacturing is the structured set of processes, standards, and checkpoints that define what a product must be, how it must be made, and what evidence confirms it was made correctly. It runs from design review and component qualification through in-process inspection, pilot validation, golden sample approval, and pre-shipment verification. The goal isn’t to inspect quality in at the end, it’s to build quality in from the start, so the final inspection is a confirmation, not a surprise.
How does a manufacturing partner manage quality?
A manufacturing partner who actually manages quality does it across every stage of production, not just at final inspection. That means DFM review before tooling, component qualification before the line starts, in-process gates with defined pass/fail criteria, a pilot run before scaling, a golden sample approved before mass production, and pre-shipment inspection against that standard. And when a gate fails, production stops until the root cause is resolved. That last part is what separates a real QA system from a compliance exercise.
What is a golden sample in manufacturing?
A golden sample is the master reference unit, the first fully approved product produced from production tooling and components, inspected against the complete QC standard, and signed off by both the manufacturer and the client. Once approved, it’s stored as the non-negotiable quality benchmark for the entire production run and all future reorders. It eliminates subjective interpretation of what “correct” looks like, giving inspectors and operators a physical standard to compare against rather than a written description to interpret.
