Full title and description

STB VDI 2221 Blatt 1 — 2019-11: Guideline for a systematic approach to the development and design of technical systems and products (Part 1). This document presents the fundamentals and recommended methodical steps for product development, from task definition through conceptual design to embodiment and detail design. The original text is in German and follows the VDI (Verein Deutscher Ingenieure) practice for engineering design methodology.

Abstract

VDI 2221 Blatt 1 (2019-11) defines a structured, repeatable workflow for engineering design. It describes the stages of problem analysis, requirement formulation, function-structure development, principle-finding and concept generation (e.g., morphological analysis), evaluation and selection of solution concepts, and documentation of results. The guideline emphasizes clarity in task formulation, iterative refinement, traceability of design choices and use of proven methods to increase efficiency and quality in product development.

Scope

This guideline sets out the scope and sequence of activities for systematic product development applicable to mechanical and mechatronic products. It covers methods for defining and structuring requirements, deriving functions, generating and documenting solution principles and concepts, evaluating alternatives and preparing design documentation. The scope is methodological rather than prescriptive for specific technologies; it is intended to be applied across industries and product types to improve repeatability and transparency of the design process.

Key topics and requirements

• Definition and clarification of the design task and customer/market requirements.
• Function decomposition and function-structure modelling.
• Principle-finding and generation of solution concepts (including morphological charts and creativity techniques).
• Systematic evaluation and selection of concepts (criteria setting, weighting, and decision matrices).
• Iterative refinement from conceptual to embodiment and detail design, with traceability of decisions.
• Documentation requirements for design rationale, specifications and change control.
• Recommendations for integration of interdisciplinary teams and consideration of manufacturability, cost and safety constraints.

Typical use and users

Engineers and product developers in mechanical, mechatronic and industrial product design use VDI 2221 Blatt 1 as a reference for structuring design projects. Typical users include R&D teams, design departments, product managers, engineering consultants, and academic instructors teaching systematic design methods. It is used to establish company design workflows, to train staff in methodical design, and to improve the consistency and documentation of development projects.

Related standards

Closely related documents and standards include other parts of the VDI 2221 series (subsequent Blätter/parts that provide detailed extensions or industry-specific guidance), standards on product safety and risk (e.g., ISO 12100), quality management standards (e.g., ISO 9001) and standards addressing design verification, validation and lifecycle aspects. Organizations commonly use VDI 2221 in combination with neighbouring VDI/DIN/ISO guidance for manufacturing, ergonomics and regulatory compliance.
