R&R is the acronym for Repeatability and Reproducibility, two fundamental components of the study of measurement system capability. This type of study, also known as Gage R&R, evaluates whether a measurement system (manual or automated) is accurate, reliable, and consistent, regardless of who performs it or when the measurement is
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
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.
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
A Pilot Run, also known as a pilot batch, is a strategic and intermediate phase in the industrialization of a new product. It serves as a "dress rehearsal" before the official start of mass production. During this stage, small quantities of the product are manufactured using the same equipment, processes,
