What is APQP ? APQP Phases | APQP Checklist

APQP – Advanced Product Quality Planning is a structured approach that is used to design and develop the product and process to meet customer needs and expectations.

Advanced Product Quality Planning tool is extensively used by automotive industries to assure quality and performance through effective planning.

APQP is one of the important tools among the five core tools of the IATF 16949:2016 standard.

Apart from Advanced Product Quality Planning, the other automotive quality core tools are:

Explore-> Production Part Approval Process-PPAP
Explore-> Failure Mode and Effect Analysis-FMEA
Explore-> Measurement System Analysis-MSA
Explore-> Statistical Process Control-SPC

APQP-Advanced Product Quality Planning Objectives

Advanced Product Quality Planning objective is to :

Facilitate effective communication with everyone involved in the APQP process.
Timely Completion of all required steps.
No or minimal quality complaints.
Assure product and process quality and performance.
Meeting customer’s requirements, needs, and expectations.

APQP Phases | APQP Phases Input and Output

There are five phases in the APQP process :

Phase – 1: Plan & Define Program
Phase – 2: Product Design & Development
Phase – 3: Process Design & Development
Phase – 4: Product & Process Validation
Phase – 5: Feedback & Corrective Action

APQP-ADVANCED PRODUCT QUALITY PLANNING | APQP Phases

Phase – 1 : Plan & define program

The purpose of this phase is to ensure that customer’s needs and expectations are clearly understood.

In planning and defining a quality program it is essential to do all work with the end customer in mind.

Inputs

Understand the Voice of the customer
- Market research
- Historical warranty & quality information
- Team experience
Business plan/marketing strategy
Product/process Benchmark data
Product and process assumptions
Product reliability studies
Customer inputs-such as product identification & traceability, special quality characteristics, and packaging requirements, etc.

Outputs

Design goals
Reliability & quality goals
Preliminary bill of material-BOM
Preliminary process flow chart-PFC
A preliminary listing of special product & process quality characteristics
Product Quality Assurance plan
Management support

Phase – 2: Product design & development

The purpose of this phase is to develop design features into nearly the final form of the product.

The NPD team or product quality planning team considers all design factors in the planning process to ensure that the final product must meet the customer’s expectations.

The design factors must be taken into consideration even if the responsibility for design is owned by the customer.

Inputs

Inputs are derived from the outputs of phase – 1 (See Phase-1 outputs)

Outputs

DFMEA – Design Failure Mode & Effects Analysis
DFMA or DMA – Design for Manufacturability & Assembly
Design Verification Plan and Report
- Design Verification through Prototype Model
- Design verification through Product Testing
Prototype control plan
Engineering drawings review
Engineering specifications review
Material specifications review
Drawing & specification changes
Target setting for Productivity and Process capability
Gauge /testing equipment requirements
New tooling/equipment and facilities requirement review
Team feasibility commitment sign off

Phase – 3: Process Design and Development

The purpose of this phase is to develop an effective management system to assure that customer’s needs and expectations are met.

In this phase, the manufacturing system/processes, PFMEA, and control plans are developed to achieve the right quality products.

Inputs

Derived from the output of phase -2 (See Phase-2 outputs)

Outputs

PFD – Process Flow Diagram
PFMEA – Process failure mode and effects analysis
Pre-Launch Control Plan
Floor plan layout
Packaging standards
Measurement System Analysis Plan
Data for Quality, Reliability, Measurability, and Maintainability
Method of rapid detection and feedback
Result of Error-proofing activities

Phase – 4: Product and Process Validation

The purpose of this phase is to validate the manufacturing process through a production trial run and to finalize the Production control plan.

During the production trial run process, the product quality planning team verify that the control plan and process flow chart are being followed strictly and assures that the manufactured products meet the customer’s requirements.

Inputs

Derived from the output of phase -3 (See Phase-3 outputs)

Outputs

Production trial run
Production control plan
Measurement systems evaluation
Preliminary Process capability – Cp and Cpk study
Production part approval – PPAP
Production validation testing
Packaging evaluation
Quality planning sign-off and management support

Phase – 5: Feedback, Assessment & Corrective Action

The aim of this phase is to make continual improvements in the product and process to enhance customer satisfaction level.

The outcomes of the production trial run are evaluated in this phase to ensure that the products satisfy the customer requirements.

Inputs

Derived from the output of phase – 4 (See Phase-4 outputs)

Outputs

Reduced Variations (Common and Special cause of Variations)
Improved Customer Satisfaction
Improved Delivery and Services
Effective Use of Lessons Learn/ Best Practices

Activities includes in this phase to enhance customer satisfaction are:

Evaluation of Effectiveness of APQP efforts based on customer feedback.
Making the necessary changes to correct non-conformance/deficiencies.
Continuation of Customer and Supplier partnership.
Organization participation in problem solving and continual improvement activities.
