NPI (New Project Implement) Project全过程各阶段定义,特性,要点:

BCA (Business Case Approval) 阶段: 项目立项可行性评审阶段

项目商务事项认可过程,项目可行性评估,确定是否同意进行立项,确认立项后,项目启动,召开Kick Off Meeting,组建项目小组.

重点: 确认项目是否立项 (规划层经营层)

PD (Product Definition) 阶段: 产品详细定义评审阶段

产品系统框架确立完成并被评审,项目Development Schedule确立。

重点: 项目产品定义是否合理,Development Schedule确立。

PS: 一般情况下,满多公司不会对BCA和PD阶段做太明确的阶段区分,一般整合到一个阶段,即项目立项可行性评审阶段。

EVT (Engineering Verification Test) 阶段: 工程样品验证测试评审阶段

Identify design problems and solving them as early in the design cycle, verify the design meets pre-determined specifications and design goals. Consists of Basic Functional Tests, Parametric Measurements, Specification Verification.

重点: Ensures basic unit performance to design goals and specifications。

PS: 此阶段一般要完成如下资料/事项:

Product /Engineering Specification

Design Verification Test Plan (Basic Test, Compatibility Test, EMI)

Test Equipment and Tooling

Test Process, Test Guideline and Test Program

Software

Circuit Schematic

PCB Layout

3D & 2D & Exploded Drawing

Surface & Artwork & Packaging

Pre—BoM

Cost Review

Failure Analysis and Corrective Actions

EVT评审会议

DVT (Design Verification Test) 阶段: 设计样品验证测试评审阶段

Design refinement。 Revise and improve the design to meet performance and design requirements and specifications。 Deliver objective, comprehensive testing verify all product specifications, interface standards and diagnostic commands. Consists of Functional Testing (including Usability), Performance Testing, Climatic Testing, Reliability Testing, Compliance Testing。

重点: 确认是否合符产品定义要求,可否批量生产.

PS: 此阶段一般要完成如下资料/事项:

Design Verification Test Complete (Basic Test, Compatibility Test, EMI)

Basic Test包括: a: Function Test

b: Safety Test (主要包括: Hit-Pot, 绝缘电阻测试, Current Leakage, 接地测试) c: Environment Test

d: Mechanical Test (主要包括: Vibration Test, Drop Test) Compatibility Test包括: a: 硬件与软件之兼容性 b: 硬件与硬件之兼容性 EMI Test: 抗静电,电磁干扰

Safety Certification

Design Change (according to the design change information,files/drawing/software/program。。。)

Modify BoM

制程文件试用的制作

modify all related design

AVL (Approved Vendor List)

Failure Analysis and Corrective Actions

DVT评审会议

PVT (Production/Process/Pilot Run Verification Test) 阶段: 小批量过程/生产验证测试评审阶段

Verify design has been correctly implemented into production, consists of Compatibility Verification Testing and Reliability Testing。

重点: 能否量产

PS: 此阶段一般要完成如下资料/事项:

Failure Analysis and Corrective Actions

各种制程文件修改并正式发行

Engineering Change

针对变更(小变更)做相应测试

Tooling Verification

Approval Sheet / File

Compatibility Verification Test

Reliability Test

制程能力报告

PP Approval Meeting

Golden Sample

产品资料release

MVT (Mass Production Verification Test) 阶段: 量产验证测试阶段

验证量产时产品的大批量一致性.

MP (Mass Production)阶段: 量产阶段

PS: 一般情况下,满多公司不会对MVT和MP阶段做太明确的阶段区分,一般整合到一个阶段,即MP阶段,此阶段侧重制程能力,产品品质持续改善及成本cost down。
