DFT – Design for Testability is an engineering approach that consists of designing a product from the start to facilitate its testing during the validation, production, and maintenance stages. The goal of DFT is to reduce test time, increase coverage, facilitate fault diagnosis, and decrease the total cost of quality.
Product Engineering is the discipline responsible for planning, developing, validating, and technically monitoring a product from its conception to its mass production. It operates at the interface between R&D, industrialization, testing, purchasing, quality, and the final customer, ensuring that the product is functional, manufacturable, testable, reliable, and competitive.

In addition, AJOLLY Testing provides advanced test data analysis to identify failure root causes related to the process, machine, or operator, using essential indicators such as: FPY (First Pass Yield) – tracks yield loss at first test cycle. Top Failures – statistics of most frequent failure modes. CPK (Process Capability
The terms DUT (Device Under Test) and UUT (Unit Under Test) refer to the unit, module, product, or system being subjected to tests, measurements or validations during a testing process. This unit can be electronic, mechanical, electromechanical, optical, RF, pneumatic, or hybrid, depending on the application sector. The DUT/UUT is
