What Is New Product Introduction?

NPI is the controlled path that moves a product from concept and design through prototype learning, engineering validation, design validation, production validation and release. It connects technical decisions with the people, evidence and manufacturing controls needed for a stable launch.

For a precision machining supplier, NPI begins with controlled design inputs and ends when the approved revision, machining process, inspection plan, material and finishing sources, traceability requirements and production records are ready for repeat orders. Product requirements and final functional approval remain with the customer; our role is to make manufacturing risk visible and provide reliable component and process evidence.

Why A Structured NPI Process Matters

A disciplined launch process reduces late design changes, connects validation to manufacturing evidence and gives every release decision a defined owner and record.

Earlier Risk Visibility

Manufacturing, material, inspection and supply risks are reviewed while the drawing and production plan can still be changed efficiently.

Shorter Industrialization Path

Defined inputs, owners, reviews and release criteria reduce avoidable loops between quotation, prototyping, validation and production.

Controlled Cost And Lead Time

Process selection, tolerance strategy, workholding, inspection effort and outside processing are considered before recurring cost is locked in.

Stronger Production Evidence

Prototype learning is converted into controlled programs, work instructions, inspection plans, traceability records and repeatable release criteria.

NPI Process For Precision Machined Parts

The seven-stage framework converts design intent into a verified manufacturing process. The exact build quantities, tests and release criteria are agreed for each program.

  1. 01

    Requirements And Feasibility

    Confirm the released drawing or current development revision, 3D model, intended function, critical characteristics, material, forecast quantity, target dates and required records. Engineering review identifies open questions, manufacturing constraints and the first build’s learning objectives.

  2. 02

    Design And Process Development

    Apply DFM and broader DFX thinking to material choice, tolerances, datum structure, tool access, workholding, inspection access, finishing and total manufacturing cost. The proposed route is documented before prototype release.

  3. 03

    Prototype Build And Learning

    Manufacture development parts with controlled revisions, then inspect the agreed characteristics and record machining, material, assembly or measurement issues. Findings become specific drawing, process or test actions for the next build.

  4. 04

    Engineering Validation Test (EVT)

    Support engineering validation with representative machined components and dimensional evidence. EVT asks whether the evolving design can meet its intended engineering requirements and what must change before design validation.

  5. 05

    Design Validation Test (DVT)

    Produce parts to the more mature design and agreed configuration so the customer can validate product performance, reliability, environmental and compliance requirements. Manufacturing feedback focuses on repeatability, critical features and remaining production risks.

  6. 06

    Production Validation Test (PVT)

    Run a pilot build using the intended machines, tooling, workholding, material sources, inspection methods, finishing route, operators and packaging conditions. The goal is to demonstrate production readiness under representative conditions.

  7. 07

    Production Handover And Ramp

    Transfer the approved drawing revision, programs, setup records, process route, work instructions, inspection plan, traceability requirements and open actions into controlled repeat production. Future changes follow the agreed review and approval path.

EVT, DVT And PVT Validation Stages

Each validation stage answers a different question. Passing one gate does not replace the evidence required by the next.

EVT

Engineering Validation Test

Core Question
Does the engineering design work as intended?
Manufacturing Evidence
Prototype parts, engineering measurements, issue log and updated technical risks.
Typical Exit
Engineering requirements reviewed and actions assigned before the next design revision.
DVT

Design Validation Test

Core Question
Can the mature design meet its defined requirements consistently?
Manufacturing Evidence
Design-intent parts, complete dimensional results, material and finish records, and customer functional-test support.
Typical Exit
Design and validation evidence are sufficiently mature for production validation.
PVT

Production Validation Test

Core Question
Can the intended production process repeatedly make conforming parts?
Manufacturing Evidence
Pilot lot, representative process conditions, first-article results, process checks, packaging and production records.
Typical Exit
Manufacturing controls, capacity, quality evidence and residual actions are accepted for launch.

NPI Decision Gates

Customer gate names vary. In an IPD framework, CDCP, PDCP, EDCP, ADCP and GA provide formal decisions from concept through general availability.

  1. CDCP

    Concept Decision

    Confirm the need, application, initial feasibility and reasons to continue.

  2. PDCP

    Plan Decision

    Approve the technical route, resources, timing, cost framework and validation plan.

  3. EDCP

    Execution Decision

    Review prototype learning, technical progress and readiness for formal verification.

  4. ADCP

    Availability Decision

    Confirm required testing is complete and the product and process are ready for controlled release.

  5. GA

    General Availability

    Release the approved product and manufacturing process for normal production and supply.

Inputs, Manufacturing Outputs And Release Evidence

Each phase starts with controlled customer inputs and closes with evidence that supports the next decision.

DFX Review During NPI

Design For X expands the review beyond basic machinability so assembly, inspection, cost and lifecycle decisions are considered before production release.

DFM

Design For Manufacturing

Select practical materials, tolerances, feature geometry and machining methods that protect function while reducing instability, rework and unnecessary cycle time.

DFA

Design For Assembly

Review interfaces, fits, access, orientation and part count where machined features influence assembly time or error risk.

DFT

Design For Test

Make critical characteristics measurable by providing clear datums, probe access, functional interfaces and acceptance criteria.

DFC

Design For Cost

Balance material yield, machine time, tooling, finishing, inspection and logistics against the product’s actual performance needs.

DFE

Design For Environment

Consider material efficiency, process waste, finish selection, service life and end-of-life requirements when they are relevant to the program.

NPI Risk Management And Change Control

Risks are reviewed throughout the program, prioritized by likelihood and impact, assigned to owners and carried forward until evidence supports closure.

01

Requirements And Revision Risk

Confirm the drawing and model revision, material specification, inspection requirements and engineering change approval responsibilities before each build.

02

Technical Risk

Review difficult materials, thin walls, tool access, feature relationships, inspection access and unproven processes early.

03

Supply Risk

Qualify material and outside-process sources, confirm lead times and identify alternatives for launch-critical items.

04

Quality Risk

Connect critical characteristics to measurement methods, sampling, reaction plans and required records.

05

Schedule And Capacity Risk

Plan prototype, validation and ramp capacity around tooling, inspection, finishing and customer approval timing.

06

Change-Control Risk

Record decisions, revisions, deviations and remaining actions so obsolete instructions cannot reach production.

NPI Support For High-Reliability Industries

The NPI framework stays consistent while industry standards, product risks, customer procedures and required records determine the final validation package.

Aerospace

AS9100D change control, material traceability, risk review and AS9102 first-article planning can be built into the NPI route when required by the contract and drawing.

Semiconductor Equipment

Material condition, vacuum-facing surfaces, cleanliness, sealing geometry and measurement access are reviewed before chamber, motion and wafer-handling parts enter pilot production.

Robotics And Automation

Fits, runout, backlash-related interfaces, bearing seats and repeat-build consistency are linked to functional datums and assembly feedback.

Medical Equipment

Customer-specified medical quality records, traceability, edge conditions, cleanliness and customer validation requirements are defined before design-intent builds are released.

NPI Frequently Asked Questions

Clear answers about responsibilities, design maturity, validation and production release.

What Information Is Needed To Start An NPI Project?

Provide the latest 2D drawing and 3D model, material and finish requirements, prototype and forecast quantities, target dates, critical characteristics, intended application and the inspection or validation evidence you expect.

Does Rocentric Own EVT, DVT And PVT Approval?

The customer owns product requirements and final design or functional approval. Rocentric supports those gates with controlled machined parts, manufacturing feedback, dimensional evidence, material and process records, and representative pilot production.

Can NPI Begin Before The Drawing Is Fully Released?

Yes. Development work can use a clearly identified revision or preliminary model when responsibilities, learning objectives and change controls are agreed. Production release requires an approved design record.

How Are Design Changes Controlled During NPI?

Each build is tied to a defined drawing and model revision. Questions, deviations, decisions and corrective actions are recorded, and updated instructions are released before the next build begins.

When Is A Part Ready For Production Handover?

The design configuration, manufacturing route, tooling, workholding, inspection plan, material and finishing sources, packaging requirements and required records must be released, with remaining actions formally controlled.

Can NPI Continue Into PPAP Or AS9102 FAI?

Yes. When the customer requires formal production approval, the NPI handover can feed a PPAP submission, AS9102 first article inspection or another customer-specific qualification package.
