Quality Engineering is the branch of engineering responsible for ensuring that products, processes, and systems meet technical, regulatory, and customer requirements. It operates transversally across the entire production chain — from development to post-sales — promoting reliability, traceability, and continuous improvement. Quality Engineering ensures that what is designed, produced, and
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
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
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 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. 🏭
In the context of electronic board production (PCBA - Printed Circuit Board Assembly), the test jig is an essential equipment used to validate the electrical and functional operation of products during manufacturing. Definition of Test Jig A test jig (also called "test jig", "test fixture", or "test fixture") is a
