designslutförande

Designslutförande (design finalization) is a term used in Swedish contexts to denote the phase in product development or project management when the technical design is considered finalized and approved for production. The phase typically follows concept design and detailed design and precedes production release. Its purpose is to ensure that the design meets the specified requirements, is manufacturable, verifiable, and ready for procurement and assembly.

Key activities during designslutförande include design freeze (formally stopping design changes), finalization of technical specifications, production drawings, and the master bill of materials, validation and verification planning, and the preparation of manufacturing instructions and quality plans. A formal design review process is usually conducted, and changes are controlled through a formal change-management system. Risk assessment, such as FMEA, and considerations for design for manufacturability and design for assembly are typically applied to ensure reliability and cost targets are met. The design history file and traceability to requirements are established at this stage.

Outputs from designslutförande commonly include a released design package, bill of materials, process instructions, inspection and test plans, and readiness documentation for suppliers and production lines. The phase is closely tied to standards and regulatory requirements depending on the sector (for example ISO 9001 quality management, industry-specific standards). It also marks a baseline for configuration management and future maintenance.

Context: The term's exact definitions and processes can vary between organizations and industries, but the core idea remains a formal milestone that freezes the design and enables production without significant late changes.
