Quality Planning

Inspection requirements linked to the product and order

Define checkpoints, measurement methods, acceptance criteria and evidence before sample approval and production release.

Workflow Views

Six stages that require defined checkpoints

These views illustrate the workflow stages. A valid project record must identify the applicable model, order, method, acceptance criteria and result.

Published Evidence Register

What a buyer can review now

This register separates published ChiZe catalog evidence from order-specific records. It prevents a catalog image from being treated as compatibility, inspection or test evidence.

ProgramPublished nowOrder control
Seats & saddles12 platform pages organize 150 variants with product images, model codes, catalog dimensions and reference weightsMaterials, mounting, finish, packaging and approval sample
Drivetrain322 ChiZe model records with listed configuration fields and clearly identified series-level visualsExact model appearance, interfaces, compatibility, finish and test requirement

Control Plan

Quality control matrix

The exact checkpoints depend on the product and buyer requirement. This matrix establishes the minimum structure for project discussion.

Validation Planning

Testing must match the final claim.

Do not infer performance or compliance from a catalog image. Confirm the applicable standard, method, sample, conditions and acceptance criteria before testing.

Order-Level Evidence

Four records to agree before release

Evidence is useful only when it is traceable to the product revision and order requirement.

01

Controlled specification

Materials, dimensions, interfaces, appearance, identification and revision.

02

Approved reference

Sample, drawing, color standard, artwork and packaging reference.

03

Inspection requirement

Checkpoint, method, frequency, sample size and acceptance criteria.

04

Validation evidence

Method, conditions, equipment, result, report identity and approval owner.

Material & Market Inputs

Compliance starts with a defined market.

For seating projects, define the cover, foam, base or shell, rail or bracket, fasteners, color and branding requirements. For drivetrain and brake projects, define the component materials, finish, mating interfaces and operating conditions relevant to the application.

Any REACH, PAHs, Prop 65 or other market-specific requirement must identify its scope, applicable substance list, report expectations and target market during the RFQ review.

Define Quality Evidence With the RFQ

Share the product, application, target market, required checks and any applicable test or compliance criteria.
