Full title and description

Application of statistical and related methods to new technology and product development process — Part 1: General principles and perspectives of quality function deployment (QFD). This part provides an overview of QFD concepts, purposes, users and tools used to translate customer and stakeholder needs into design and development activities; it describes methods and perspectives rather than management-system requirements.

Abstract

This part of ISO 16355 describes the Quality Function Deployment (QFD) process, its purpose, typical users and the principal tools and information flows used to convert voice(s) of customer and business into measurable technical requirements. It explains QFD concepts, information structuring, prioritization and translation/transfer of priorities through development dimensions (quality, cost, reliability, safety, lifestyle/emotional quality, security, etc.), and how QFD integrates with product development activities such as concept engineering, parameter/tolerance design, optimization, prototyping, testing and start-up. It does not prescribe organizational policy or management-system requirements.

Scope

Defines the purpose, scope and perspective for applying QFD within new technology and product development. It covers the roles and activities needed to capture voices of customer, business and other stakeholders, structure and prioritise needs, and translate those needs into technical responses and measurable targets. The standard focuses on methods, information flows and integration into development processes; it does not set requirements for an organisation’s management system or prescribe company policy.

Key topics and requirements

• Foundations and core concepts of QFD: definitions of customer need, function, voices (voice of customer, business, project, engineer, operations, commercialization, after-sales, environment).
• Information structuring and prioritization methods, including guidance on quantitative translation (e.g., AHP-like approaches) to support valid mathematical operations.
• Types of QFD projects and recommended methods and tools for different scales and constraints (full deployment, Blitz/rapid QFD, Matrix of Matrices, 4‑phase models).
• Cross-functional team roles and responsibilities, and guidance for effective multi-disciplinary collaboration throughout development.
• Translation and transfer of priorities and metrics between information sets (customer needs → functions → parts → manufacturing/process).
• Deployment across dimensions: quality, cost, reliability, safety, emotional/lifestyle attributes and security considerations.
• Integration with engineering activities: concept engineering, parameter/tolerance design, optimization, prototyping, testing/validation and build/start-up.
• Downstream considerations for packaging, logistics, commercialization and after-sales support.
• Emphasis on practical tools and perspectives rather than prescriptive organizational requirements.

Typical use and users

Used by cross-functional teams involved in new product, service or system development: product managers, systems and design engineers, R&D, quality and reliability engineers, marketing and sales, procurement and supply-chain professionals, manufacturing and operations, regulatory and compliance, testing and validation, and service/support teams. Typical applications include converting voice of customer into prioritized technical specifications, informing design optimization and prototyping, and structuring deployment of quality, cost, reliability and safety into part- and process-level designs.

Related standards

Other parts of the ISO 16355 series (parts 2–9) provide complementary and more detailed guidance on specific activities such as acquiring qualitative and quantitative voice of customer, VoC analysis, transformation into design, optimization, digitalized products/security and commercialization. ISO 16355-7 addresses security/deployment aspects. The series is produced under ISO/TC 69 and related technical subcommittees.

FAQ

Q: What is this standard?

A: ISO 16355-1:2021 is Part 1 of the ISO 16355 series and provides general principles and perspectives for Quality Function Deployment (QFD) as applied to new technology and product development.

Q: What does it cover?

A: It covers QFD concepts, voices (customer, business, project, engineer, operations, etc.), information structuring and prioritization, methods to translate customer needs into technical requirements, integration with development activities (concept, design, prototyping, testing) and deployment across dimensions such as quality, cost, reliability and safety. It describes methods and perspectives but does not set organisational management-system requirements.

Q: Who typically uses it?

A: Cross-functional development teams: product and program managers, R&D and design engineers, quality and reliability engineers, marketing, manufacturing, procurement, testing, regulatory and after-sales/support personnel in hardware, software, services and systems organisations.

Q: Is it current or superseded?

A: ISO 16355-1:2021 is the current second edition published in May 2021; it replaced the earlier 2015 edition of ISO 16355-1.

Q: Is it part of a series?

A: Yes. ISO 16355-1 is Part 1 of the multi-part ISO 16355 series that covers the broader QFD and VoC lifecycle. Other parts (e.g., parts 2–8 and planned parts) provide more detailed guidance on specific activities such as acquiring VOC, analysis, transformation into design, optimization, digitalization/security and commercialization.

Q: What are the key keywords?

A: QFD, voice of customer (VOC), requirement translation, prioritization, AHP, product development, design optimization, prototyping, cross-functional teams, deployment, reliability, safety.
