# Product Design Process: From Concept to Production Solve engineering pain points with technical solutions that optimize the product design process from start to finish. ## (3DEXPERIENCE EXPRESS SEO LP1 RT)Definition of Product Design Process The **product design process** is an engineering workflow that turns product requirements into a validated, production-ready definition. It moves from ideation and 3D modeling through validation, **design iteration** and the **prototyping process** toward manufacturing handoff. As complexity grows, decisions made throughout these processes become more interdependent. Mechanical, electrical, systems teams must evaluate alternatives, manage system-level changes and resolve production constraints without losing design intent. ## (3DEXPERIENCE EXPRESS SEO LP1 PoB)Four Stages of Product Design ## (3DEXPERIENCE EXPRESS SEO LP PoB AT1)Requirements and concept design Starting from defined requirements, **concept design** explores and compares engineering alternatives. Integrated 3D ideation and surface modeling help teams assess options in context and carry selected geometry into engineering. ## (3DEXPERIENCE EXPRESS SEO LP PoB AT2)Detailed design Once a direction is selected, the focus shifts to interfaces, tolerances, assemblies and multidisciplinary dependencies. Associative models and system definitions maintain changes across components and disciplines throughout **detailed design.** ## (3DEXPERIENCE EXPRESS SEO LP PoB AT3)Design iteration As the product matures, performance and integration issues need to surface before becoming physical rework. Embedded design checks and virtual validation help identify integration and performance issues earlier in the cycle, enabling faster **design iteration**. ## (3DEXPERIENCE EXPRESS SEO LP PoB AT4)Prototyping and manufacturing handoff The **prototyping process** helps verify performance and exposes any remaining issues before manufacturing. Aligning validated data with drawings, BOMs and manufacturing deliverables supports a controlled handoff to **manufacturing**. ## (3DEXPERIENCE EXPRESS SEO LP1 RT2)Why an Effective Product Design Process Matters A geometry change can affect interfaces, BOMs and manufacturing outputs. Maintaining continuity makes these dependencies visible and keeps engineering decisions traceable across **product development stages**. For smaller engineering teams, the design process is particularly important as there is less capacity to absorb duplicated work, fragmented design files and costly errors. ## (3DEXPERIENCE EXPRESS SEO LP1 HL)How 3DEXPERIENCE® PLM Express Supports the Product Design Process Streamline your workflows with AI-driven design engineering, which unites 3D modeling, static simulation and multidisciplinary collaboration in a single cloud environment.

The product design process is an iterative engineering workflow that converts requirements into a validated, manufacturing-ready product definition. It connects **concept design,** 3D modeling, **detailed design,** multidisciplinary system integration, **design iteration** and the **prototyping process.** Maintaining these activities within a consistent product context helps teams preserve design intent, evaluate changes across disciplines and keep engineering data aligned with downstream drawings, BOMs and manufacturing deliverables. ## What are the four stages of product design? 1. **Requirements and concept design:** Establish performance, user, system and manufacturing constraints, then compare potential design directions. Develop and assess 3D ideas, surfaces and configurations before carrying selected geometry into engineering. 2. **Detailed design:** Define parts, assemblies, interfaces, tolerances and multidisciplinary system requirements. 3. **Design iteration** **and validation:** Use simulation, digital mock-ups and engineering reviews to evaluate performance and refine the design. 4. **Prototyping and manufacturing handoff:** Incorporate test results into the controlled product definition and release validated drawings, BOMs and production deliverables. Validation findings, interface conflicts and prototype results may require teams to revisit earlier design process decisions while keeping the broader product definition consistent. CATIA’s design and engineering approach similarly connects these stages for rapid 3D ideation, detailed product definition, virtual validation and downstream manufacturing preparation. ## What are the seven steps in the design process? The seven steps can be structured around engineering maturity in the design process: 1. Capture product requirements and technical constraints. 2. Generate and compare potential concepts. 3. Select and mature the preferred design direction. 4. Create the detailed 3D product definition. 5. Coordinate assemblies, interfaces and multidisciplinary systems. 6. Simulate, validate and refine the design. 7. Release approved product data for prototyping and manufacturing. The **3D**EXPERIENCE PLM Express Design Engineering offer reflects a connected workflow through unified product structures, integrated CAD and BOM management, multidisciplinary definition management and associative drawing generation. ## What is the difference between product design and product development? **Product design** focuses on the engineering definition of the product: How it looks, functions, performs, fits together and satisfies its requirements. **Product development** encompasses the complete path of a product from ideation to market, including requirements, project planning, design, engineering, sourcing, manufacturing, launch and lifecycle processes. In a connected PLM environment, design definitions can stay associated with product structures, planning activities, workflows and downstream enterprise processes throughout development. ## Looking to bring the design process, validation and product data into one engineering environment?
