Verifying product performance through testing is critical, but can become costly and time-consuming if not designed for upfront. DFT focuses on enabling effective testing of products throughout development and manufacturing.
DFX, or Design for X, refers to a systematic approach to designing products and processes to achieve specific objectives or characteristics. The "X" represents various targets like manufacturability, reliability, usability, etc. DFX helps companies optimize their products across the entire product lifecycle.
DFX represents a holistic approach to product development that optimizes the design against multiple objectives. At Boston Engineering, DFX is a core part of our product development process. We focus on several key DFX areas that align with our expertise:
- Design for Manufacturability (DFM)
- Design for Assembly (DFA)
- Design for Cost (DFC)
- Design for Testability (DFT)
- Design for Reliability (DFR)
- Design for Serviceability/Maintainability (DFS)
- Design for Usability (DFU)
- Design for Modularity (DFMo)

Here is an introduction to Design for Testability (DFT):
Design for Testability involves anticipatory development to design products with testing in mind. By designing for testability, companies can optimize test coverage while minimizing cost and time to market.
Key DFT principles include:
• Incorporating test points and interfaces on electronic modules
• Designing mechanical assemblies for easy access and fixturing
• Defining critical test parameters and tolerances early
• Utilizing modeling and simulation for virtual testing
• Specifying standardized tests leveraging industry best practices
• Designing products for automated testing and data collection
Example Projects:
• Developing a diagnostic self-test routine for a medical device, reducing external test time by 70%
• Implementing common test fixtures and methods for an electronic product family, cutting fixture costs by millions
Where Problems Arise
Insufficient DFT leads to issues like:
• Unable to fully validate product performance due to limited visibility
• Excessive manual testing time and cost
• Custom test fixtures needed for low-volume products
• Scrap and rework due to manufacturing defects
• Extended test development time delaying new product launch
Expert DFT analysis early in design could prevent these pitfalls.
DFT experts like Boston Engineering provide:
• Proven DFT methods tailored to your specific product line
• Knowledge of the latest testing technologies and tools
• Skills to quantify tradeoffs on test approaches and diagnostic capabilities
• Abilities to define effective test requirements and strategies
• Insight on virtual modeling and simulation to reduce physical testing
While it's tempting to rely solely on internal resources and capabilities, working with an experienced Design for X firm can offer a multitude of benefits that accelerate the design, development, and performance of your new or existing product. These benefits include a streamlined process, cost controls, accelerated timelines, and mitigation of failure risks - before the product has even launched!

Understanding the Importance of a DFX approach
Applying Design for X (DFX) methodologies upfront in product development optimizes the entire lifecycle by improving manufacturability, testability, reliability, usability, and other critical characteristics. This avoids costly redesigns later on, facilitates high-quality products that satisfy customers, reduces manufacturing and service costs, and supports flexibility through modularity and platforms. The holistic perspective of DFX drives efficient, cost-effective delivery of successful products that provide competitive advantage. Investing in DFX early pays dividends across the entire product lifespan.
