ISO 11748-2:2001

Overview

ISO 11748-2:2001, titled Road vehicles - Technical documentation of electrical and electronic systems - Part 2: Documentation agreement, is an international standard developed by ISO. It provides a comprehensive framework for establishing documentation agreements between partners involved in the development of on-board electronic control systems for road vehicles. This standard outlines the guidelines and requirements for structuring and content of documentation exchanges, ensuring clarity, consistency, and mutual understanding throughout the development process.

By following ISO 11748-2, organizations can streamline communication, minimize misinterpretation, and improve project efficiency during the documentation of electrical and electronic systems. The standard is particularly relevant for automotive manufacturers, component suppliers, software developers, and other stakeholders engaged in collaborative vehicle system development.

Key Topics

ISO 11748-2:2001 focuses on the following essential elements for technical documentation agreements:

• Subject Definition: Clearly identifies the specific system or development to which the agreement applies.
• Partnership Identification: Lists all participants responsible for creating, receiving, or managing documents, along with their contact information.
• Document Partitioning: Describes the decomposition of the vehicle's electrical or electronic system into subsystems for detailed documentation.
• Development Process Phases: Outlines the process stages, synchronizing document exchanges with project milestones.
• Document Categories: Specifies types of documents such as requirements, specifications, design, verification, and validation documents.
• Content Requirements: Details mandatory versus optional elements for each document type, referencing related standards where applicable.
• Document Exchanges: Establishes scheduling, unique identification, authorship, recipients, and applicable process phase for each document transfer.
• Documentation Management: Sets out procedures for approval, distribution, modification, filing, and ownership of shared documents.
• Exchange Media: Defines acceptable formats and media (e.g., database files, graphic formats, PDF, HTML) for document exchange.

Applications

Implementing ISO 11748-2:2001 adds practical value across the automotive sector by:

• Clarifying Responsibilities: Clearly assigning documentation tasks, reducing ambiguity when multiple companies or teams collaborate.
• Improving Communication: Establishing a common framework for technical document exchange streamlines communication among partners.
• Facilitating Compliance: Aligning with internationally recognized standards supports regulatory compliance and quality assurance.
• Enhancing Project Management: Enabling better tracking and control of documentation through clear schedules and document management practices.
• Reducing Rework: Well-defined documentation agreements help prevent errors and omissions, reducing costly rework in development.
• Supporting Lifecycle Management: Structured documentation supports maintenance, upgrades, and future development by providing accessible, standardized records.

Typical users of ISO 11748-2 include:

• Automotive OEMs and Tier 1/Tier 2 suppliers
• Engineering service providers
• Software developers for vehicle systems
• Project managers overseeing technical system development

Related Standards

To ensure comprehensive alignment and effective documentation, organizations should consider these related standards:

• ISO 11748-1: Road vehicles - Technical documentation of electrical and electronic systems - Part 1: Content of exchanged documents - details the specific content requirements for documents referenced in the agreement.
• ISO 11748-3: Road vehicles - Technical documentation of electrical and electronic systems - Part 3: Application example - provides illustrative examples of documentation agreements in practice.
• ISO/IEC Directives: Guidelines for the development, structure, and drafting of international standards relevant for harmonizing documentation.

By integrating ISO 11748-2 with these related standards, organizations can establish robust, transparent, and standardized documentation practices throughout the road vehicle system development life cycle. This standard is instrumental in ensuring the quality, traceability, and clarity of technical exchanges in the automotive industry.
