In the world of product development, understanding and effectively implementing the product design process is crucial. An integral component of this process is assessing the Technology Readiness Level (TRL) of a product or system. This article will explore the different stages of the product design process and the role TRL plays in bringing a product from conception to market.
The product design process
The product design process can be broken down into the following stages:
- Idea Generation and Concept Development: The first stage involves brainstorming, research, and identifying potential product ideas to address consumer needs or solve existing problems. A product concept is then created, outlining the general idea and key features of the proposed product.
- Feasibility Analysis: Once a concept is developed, a feasibility analysis is conducted to determine the practicality, technical viability, and financial viability of the idea. This involves considering factors such as market demand, production costs, and potential risks associated with the development and launch of the product.
- Concept Refinement: Based on the feasibility analysis, the product concept is refined, and design iterations are created to address any concerns or limitations identified in the analysis.
- Prototype Development: With a refined concept, a physical or digital prototype is developed to test and validate the product’s functionality, design, and performance.
- Testing and Evaluation: The prototype is rigorously tested for functionality, durability, and user experience. This stage may involve further iterations of the design to address any issues that arise during testing.
- Final Design and Production: Once the prototype is deemed satisfactory, the final design is created, and the product is moved into production. This stage may also involve securing necessary certifications, patents, and approvals.
Technology rediness levels (TRLs)
TRL is a systematic measure used to assess the maturity of a technology or system. Developed by NASA and later adopted by other organizations, TRLs range from 1 (lowest) to 9 (highest) and serve as an effective tool for managing and mitigating risk throughout the product development process.
The nine TRLs can be defined as follows:
- TRL 1: Basic principles observed and reported
- TRL 2: Technology concept and/or application formulated
- TRL 3: Analytical and experimental critical function and/or proof-of-concept
- TRL 4: Component and/or breadboard validation in a laboratory environment
- TRL 5: Component and/or breadboard validation in a relevant environment
- TRL 6: System/subsystem model or prototype demonstration in a relevant environment
- TRL 7: System prototype demonstration in an operational environment
- TRL 8: Actual system completed and qualified through test and demonstration
- TRL 9: Actual system proven through successful mission operations
Conclusion
Understanding and implementing the product design process while considering the TRL of a product or system is crucial for successful product development. By considering these stages and TRLs, businesses can better manage risk, allocate resources, and improve the overall success rate of their products.
