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
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.
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 CPK (Process Capability Index) is a statistical indicator used to measure how well a process is performing in relation to its tolerance specifications. It shows whether the process is centered and stable enough to produce within the acceptable limits defined by the design or standard. Why is CPK important?
KPIs (Key Performance Indicators), or Key Performance Indicators, are metrics used to monitor and evaluate the performance of industrial processes, quality tests, production lines, and even technical teams. They allow for data-driven decisions, identify bottlenecks, optimize processes, and ensure continuous improvement — one of the pillars of success in modern
The validation of a product or system requires different types of tests, depending on its application sector. Each segment has its own criteria for compliance, traceability, and technical requirements. Below, we detail the most common types of tests organized by sector, based on the practical experience of AJOLLY Testing. 🏭
