MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair) are two fundamental indicators for measuring the reliability and maintainability of industrial systems, test equipment, and automated production lines. They help to quantify the performance and robustness of a technical solution, revealing not only the frequency of failures but
The MES (Manufacturing Execution System) is a real-time production control and management system responsible for connecting the shop floor with planning (ERP), quality, and engineering systems. It allows monitoring, tracking, documenting, and optimizing production execution, ensuring full visibility of what is happening on the line. Function of MES in the
PDCA is a continuous improvement methodology used to plan, execute, check, and act on processes, aiming to eliminate failures, standardize best practices, and increase efficiency. It is widely used in quality management, industrial processes, testing laboratories, and production engineering. What does PDCA mean? StageMeaningObjectiveP – PlanPlanIdentify problems and define goals
The Pareto chart is a statistical tool used to identify and prioritize the main causes of failures in a process. It is based on the Pareto Principle (80/20), which states that about 80% of problems come from 20% of the causes. When applied to test engineering and production, the Pareto
Measurement is the technical process of quantifying a physical, chemical, or logical quantity by comparing it with a known standard. It is the basis for validating products, processes, and systems — ensuring quality, safety, traceability, and regulatory compliance in industrial, laboratory, and clinical environments. In practice, there is no reliable
Six Sigma is a quality management methodology focused on reducing defects, variability, and waste in industrial and organizational processes. Its goal is to achieve an extremely high level of performance, where processes generate a maximum of 3.4 defects per million opportunities (DPMO). Origin and Fundamentals Created at Motorola in the
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.
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
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
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
