The FPY (First Pass Yield), or First Pass Yield, is a fundamental indicator of the efficiency and quality of a test or production process. It measures the percentage of units that pass the test on the first attempt, without the need for rework, repetition, or correction. Why is FPY important?
In production lines, rejecting a product that is technically good represents one of the most dangerous and underestimated wastes: the false positive. This type of error does not directly compromise the quality perceived by the customer, but seriously affects the efficiency, productivity, cost, and confidence in the tests. The incorrect
Electromagnetic Interference (EMI) occurs when unwanted electrical signals affect the operation of circuits and electronic systems. It can cause communication failures, instabilities, data loss, and even permanent damage. In the context of industrial production and testing, understanding and controlling EMI is essential to ensure reliability, safety, and compliance with regulatory
The CompactDAQ (cDAQ), from NI of the Emerson group, is a modular and flexible system for data acquisition (DAQ) in industrial environments, laboratories, and production lines. It combines high precision, connectivity, and modularity, making it ideal for applications where robustness, speed, and scalability are essential. With CompactDAQ, you connect sensors
PPK (Process Performance Index) is a statistical indicator that measures how well a process is performing in relation to its specifications, considering real and current data, regardless of whether the process is under statistical control or not. Unlike CPK, which assesses the theoretical capacity of the process, PPK measures the
Cycle time is the time required to complete a full operation or process — from start to finish — repeatedly. In industrial environments, it represents the production or testing pace, being one of the most critical indicators of efficiency and delivery capability. The shorter the cycle time (without losing quality),
Kaizen is a philosophy of Japanese origin that literally means "change for the better". In the industrial context, it is a systematic approach to continuous improvement, involving all employees — from the operator to the engineer — to eliminate waste, improve processes, and enhance quality. In the industrial testing environment,
Instrumentation is the set of devices, systems, and techniques used to measure, acquire, control, and record physical or electrical variables of a system. In the context of AJOLLY Testing, instrumentation is the central pillar to ensure precise, reliable, and traceable tests in industrial, laboratory, and research & development (R&D) environments.
Test software is an essential tool to automate, standardize, and record verification and validation processes in various sectors: industrial, scientific, laboratory, automotive, medical, aerospace, and technical services. Definition A test software is a program developed to control measurement instruments, execute automated test sequences, capture data, and generate reports reliably. It
