In my experience, manufacturing companies that rush a new product introduction process usually pay for it later. They see production delays, quality issues, supplier problems, and cost overruns that should have been caught earlier.
That is why the NPI process matters.
New product introduction (NPI) is not a single meeting or a checklist in Excel. It is a structured process that takes a product from an initial idea through design, validation, launch, and into mass production.
A strong NPI program reduces risk, improves product quality, and helps teams accelerate time to market without losing control of production costs.
In this guide, I will break down the seven phases of modern NPI, explain what each phase should deliver, and show how engineering, manufacturing, quality, and supply chain teams work together to move a product from concept to production.
NPI relies heavily on Product Lifecycle Management (PLM) tools to manage documentation, bills of materials (BOMs), and design changes.

What is NPI in Manufacturing?
NPI stands for new product introduction. In manufacturing, the NPI process is the structured path that takes a product from concept to volume production.
Traditionally, NPI was described in 5 to 7 phases. Today, most hardware and manufacturing companies use a more practical structure that includes EVT, DVT, and PVT as core validation stages.
If you want a simple definition:
NPI is the process of making sure a product can be built, tested, launched, and scaled with consistent quality.
NPI Phase Overview
Modern NPI is best understood as a 7-phase process:
- Define
- Feasibility Check
- EVT (Engineering Validation Test)
- DVT (Design Validation Test)
- PVT (Production Validation Test)
- Launch
- Post-Launch Improvement
This structure reflects how real products move from concept to production. Instead of treating development and validation as broad steps, EVT, DVT, and PVT break them into clear, testable stages.
How EVT, DVT, and PVT Fit Into NPI
NPI is the overall program. EVT, DVT, and PVT are the core execution phases inside it.
The typical flow looks like this:
Concept → Feasibility → EVT → DVT → PVT → Mass Production
Each stage answers a different question:
- EVT: Does the design work?
- DVT: Does the design meet all requirements?
- PVT: Can we build it at scale?
This staged approach reduces risk early, when changes are still manageable, instead of discovering problems during production.
Why the NPI Process Matters
A weak NPI process creates predictable problems.
Teams miss cost targets. Products fail quality checks. Design specifications do not match manufacturing processes. Suppliers do not have enough lead time. The final product reaches the market late, or worse, with defects.
A structured NPI process prevents that.
It gives teams a repeatable method to validate a business case, test manufacturability, manage production processes, and prepare for product launch. It is the difference between improvising and running a controlled system.
Step 1: Define
The define phase starts with the product idea, but it should never rely on intuition alone.
This NPI phase should begin with market research, market data, and customer feedback. Before engineering starts building anything, the team needs to understand customer needs, target users, product concept, and competitive landscape.
In this phase, I recommend building a business case that includes:
- Target market and market launch assumptions
- Expected production costs and margin goals
- Dates, project budget, and rough ROI
- Preliminary design specifications
- A first high-level bill of materials
Early collaboration among cross-functional teams, including engineering teams and product developers, can streamline the NPI process and accelerate time to market.
The concept stage is also where leadership should sponsor the project and identify a project manager. Someone needs to own the timeline, coordinate the project team, and keep upper management informed.
Key deliverables in the define phase:
- Product requirements document
- Preliminary BOM
- Business case
- Initial project timeline
- Acceptance criteria for success
This phase defines whether the product introduction is worth pursuing at all.
Step 2: Feasibility Check
The feasibility phase answers a direct question: can we actually build this product profitably and at scale?
At this point, the team must assess technical feasibility, manufacturing capability, supply chain readiness, and risk. This is where many projects get a reality check.
A proper feasibility check should cover:
- Can the design be manufactured with available equipment?
- Do we need a contract manufacturer?
- Can suppliers meet lead time and volume expectations?
- Can we hit cost targets after tooling, labor, and raw materials are included?
- What are the major failure modes and risk assessments?
This is also the right point for early supplier involvement. In my experience, bringing suppliers into the NPI process early reduces lead times and improves component availability. Engaging suppliers during feasibility supports better sourcing decisions and more accurate cost estimates.
For procurement and sourcing, this is where the RFQ and purchasing process becomes important. Material forecasting is critical at this stage to ensure resource availability, supplier readiness, and manufacturing alignment.
Key deliverables in the feasibility phase:
- Feasibility report
- Risk assessment matrix
- Supplier shortlist
- Initial cost model
- Go or no-go gate review
Step 3: EVT (Engineering Validation Test)
The EVT phase is where the product becomes real for the first time.
This is not about polished prototypes. It is about proving that the engineering design actually works.
Teams build the first integrated units using early BOM versions. These builds often include temporary components and incomplete documentation.
Typical EVT activities:
- First full system prototype builds
- Functional validation
- Early firmware/software integration
- Initial performance testing
- Early BOM structuring
BOM management becomes critical here. Teams deal with incomplete BOMs, frequent revisions, and early supplier sourcing decisions. Without proper revision control and supplier visibility, EVT becomes disorganized very quickly.
Real-world example: A PCB assembly works electrically but overheats under load. Engineers revise components, update the BOM, and rebuild. This iteration cycle is exactly what EVT is designed for.
Key deliverables:
- Working prototypes
- Initial BOM
- Test results and issue logs
- Engineering changes
- Early supplier input
Step 4: DVT (Design Validation Test)
DVT is where the product stops being flexible and starts being fixed.
The goal is to confirm that the design meets all requirements.
Typical DVT activities:
- Full product testing
- Environmental testing (temperature, vibration, humidity)
- Reliability testing
- Safety and regulatory certification
- Validation against specifications
The BOM should now be stable and controlled. Components are approved, suppliers are validated, and changes are tightly managed.
Poor BOM control during DVT leads to failed certifications and expensive redesigns.
Real-world example: A product fails high-temperature testing due to material deformation. The team updates materials, revises the BOM, and repeats testing. Catching this in DVT prevents field failures.
Key deliverables:
- Verified product design
- Near-final BOM
- Compliance results
- Reliability data
- Design freeze decision
Step 5: PVT (Production Validation Test)
PVT shifts the focus from design to manufacturing.
The question becomes: Can we build this product consistently at scale?
PVT uses real production conditions: production tooling, manufacturing lines, trained operators, and the final supply chain.
Typical PVT activities:
- Pilot production runs
- Process validation
- Yield analysis
- Supply chain readiness checks
At this stage, the BOM must be fully accurate and production-ready. Any mismatch between BOM, suppliers, and actual production will immediately surface.
Real-world example: A pilot run reveals a high defect rate due to unclear assembly instructions. Fixing this before mass production prevents large-scale losses.
Key deliverables:
- Pilot build results
- Qualified production line
- Manufacturing validation
- Yield metrics
- Final production BOM
EVT vs DVT vs PVT Comparison
| Phase | Primary Goal | Focus Area | Design Stability | BOM Status | Key Question |
|---|---|---|---|---|---|
| EVT | Validate engineering design | Functionality | Low | Evolving | Does it work? |
| DVT | Validate requirements | Performance & reliability | Medium to high | Controlled | Does it meet specs? |
| PVT | Validate production | Manufacturing & scale | High | Final | Can we build it at scale? |
Step 6: Launch
By the time a product reaches launch, EVT, DVT, and PVT should have already validated the design, requirements, and manufacturing process.
Launch is not where problems should be discovered. It is where a validated system is scaled.
This phase includes:
- Production ramp-up
- Operator training
- Final documentation
- Supply chain alignment
- Go-to-market execution
Mass production requires stable processes, predictable output, and controlled costs.
Step 7: Post-Launch Improvement
Once the product is launched, the work is not finished.
Teams should monitor:
- Product quality
- Customer feedback
- Production efficiency
- Cost performance
Then feed that information back into future NPI cycles.
Key deliverables:
- Lessons learned
- Cost reduction plans
- Improvement backlog
- Lifecycle updates
Cross-Functional Teams in NPI
A successful NPI process is always cross-functional.
Cross functional teams should include engineering, manufacturing engineers, quality, procurement, supply chain, operations, and marketing and sales teams. In some companies, support and service teams are included early too.
Effective NPI requires full support from upper management across all divisions and departments. The management team is responsible for overseeing project development, reviewing key phases such as project deliverables, managing budgets, and providing timely feedback to resolve blockers.
Here is what cross functional collaboration should look like:
- Manufacturing engineers join early to give DFM feedback
- Quality engineers define inspection criteria during development
- Supply chain teams get early visibility into timelines and materials
- Procurement qualifies suppliers and negotiates commercial terms
- Marketing teams provide market requirements and launch inputs
- Upper management sponsors the NPI program and removes blockers
NPI requires intense, cross-functional collaboration between engineering, procurement, marketing, and contract manufacturers.
In my experience, one of the biggest NPI failures is poor cross functional communication. Design teams make decisions without manufacturing input. Supply chain finds out too late. Quality gets involved at the end when it should be engaged from the start.
A dedicated NPI project manager should coordinate milestones, project progress, budget, gate reviews, and communication across the full project team. Regular alignment meetings support cohesion among distributed teams.
Cross-Functional Team Responsibility Overview
| Team / Role | NPI Phase Involvement | Key Contribution |
|---|---|---|
| Product Manager / Project Manager | All phases | Owns timeline, gate reviews, priorities, project budget |
| Design Engineering | Define through Validation | Product concept, design specifications, prototype changes |
| Manufacturing Engineers | Feasibility through Launch | DFM, process development, line readiness, operator support |
| Quality Team | Development through Post-Launch | Quality assurance, inspection criteria, validation, metrics |
| Supply Chain / Procurement | Feasibility through Launch | Supplier qualification, lead times, sourcing, availability |
| Marketing and Sales Teams | Define and Launch | Market needs, customer messaging, go to market strategy |
Digital Manufacturing Tools for NPI
Digital manufacturing is now a core part of effective NPI execution.
Cloud systems, digital platforms, simulation tools, CAD/CAM, and shared BOM management reduce manual handoffs and make cross functional collaboration easier. They also replace paper-based process documentation with connected, real-time data.
Digital manufacturing tools help teams:
- Share one current BOM across distributed teams
- Connect design and manufacturing systems
- Reduce manual data transfer errors
- Support rapid prototyping and revision control
- Monitor pilot builds with real-time production feedback
At OpenBOM, we use cloud-native data management to help teams connect engineering, procurement, and production. That reduces the friction that usually slows the NPI process.

NPI Best Practices
If I had to summarize the best way to improve an NPI manufacturing process, I would focus on a few fundamentals. Define acceptance criteria early, before EVT begins, and build a real business case instead of a wish list. Treat feasibility as a hard gate. Do not skip it or treat it as a formality.
BOM management and supplier alignment should evolve alongside these phases. During EVT, flexibility is expected, but by DVT, revisions must be controlled and suppliers validated. By the time a team reaches PVT, the BOM should be production-ready and fully aligned with qualified vendors.
In practice, most NPI failures come from rushing the wrong phase. If EVT is rushed, design problems carry into later stages where they are expensive to fix. If DVT is weak, products fail validation or certification. If PVT is skipped, mass production starts with untested processes.
Frequently Asked Questions
What does NPI stand for in manufacturing?
NPI stands for new product introduction. In manufacturing, it is the structured process that takes a product from initial concept through development, validation, and into mass production.
What are the phases of the NPI process?
The NPI process usually includes six phases: Define, Feasibility, Development, Validation, Launch, and Post-Launch. Some companies use 5 to 7 phases depending on industry and product complexity.
How long does the NPI process take?
It depends on complexity. Simple products may take 3 to 6 months. Complex hardware products often take 12 to 24 months, especially when tooling, qualification, and supplier readiness are involved.
What is the difference between NPI and NPD?
NPD is the broader product development process. NPI focuses more specifically on the steps required to prepare a product for manufacturing and launch.
Who is responsible for the NPI process?
An NPI project manager usually leads it, but the work is cross-functional. Engineering, manufacturing, quality, supply chain, procurement, and marketing all play a role.
What is a gate review in NPI?
A gate review is a formal checkpoint between NPI phases. Stakeholders review deliverables, risks, cost, timing, and readiness before deciding whether the project should move forward.
Quick NPI Checklist Before Launch
Before moving into full production, I recommend validating the following:
- EVT has confirmed the design works and major engineering issues are resolved
- DVT has validated performance, reliability, and compliance, and the design is frozen
- PVT has proven the manufacturing process, yield, and production readiness
- BOM is complete, accurate, and aligned with approved suppliers
- Suppliers are qualified and ready for volume production
- Manufacturing processes and work instructions are documented and tested
- Quality control criteria are defined and validated during builds
- Pilot build (PVT) results meet yield and performance expectations
- Production line, tooling, and operators are fully ready
- Cost targets are validated against real production data
This checklist helps ensure a controlled transition from validated builds to mass production.
Conclusion
New product introduction is the bridge between a product idea and a repeatable manufacturing operation. A well-structured NPI manufacturing process ensures that teams can move from concept to production with confidence, quality, and speed.
When teams follow the NPI process with discipline, they reduce risk, improve quality, and reach mass production faster. When they improvise, they create delays, rework, and unnecessary cost.
At OpenBOM, we believe engineering, supply chain, and manufacturing teams should work from the same data, not disconnected spreadsheets.
