Use of InfinityQS SPC Test

The InfinityQS SPC test is a targeted assessment designed to evaluate a candidate’s proficiency in managing, configuring, and supporting Statistical Process Control (SPC) systems using the InfinityQS software suite. As organizations increasingly rely on real-time quality monitoring, data-driven process improvement, and manufacturing intelligence, it becomes essential to identify professionals who can effectively leverage SPC platforms to enhance operational performance and ensure compliance. This test is particularly valuable during the hiring process for roles that involve quality engineering, manufacturing analytics, SPC system support, or integration with plant data sources. It enables employers to accurately gauge a candidate’s understanding of SPC concepts, data collection workflows, reporting configurations, and system automation—skills that are critical to reducing variability, improving process stability, and driving continuous improvement in production environments. The assessment covers a broad spectrum of functional areas including system setup, data integration, user support, reporting, automation, and cross-platform connectivity. Each question is designed to reflect practical use cases, allowing employers to identify candidates who are not only technically competent but also capable of applying their knowledge in real-world manufacturing scenarios. By incorporating the InfinityQS SPC test into your hiring process, you can confidently assess candidates’ ability to support scalable, data-centric quality control systems. Whether you’re hiring for a single plant or a global manufacturing network, this test ensures that your team has the expertise needed to maintain high-quality standards and unlock the full value of SPC systems.

Skills measured

Evaluates understanding of how InfinityQS captures, visualizes, and processes data through the Proficient Dataflow engine and SPCMI. Covers basic setup, real-time operator interface, control chart usage, rule violations (e.g., Western Electric), and data collection workflows. Assesses ability to navigate modules, interpret chart statuses, and input measurements for quality tracking.

Assesses knowledge of managing InfinityQS database schema and configuration settings using Database Manager. Includes tasks like creating and managing part/process/characteristic hierarchies, linking sampling plans, maintaining data tables, setting control limits, and managing licensing aspects such as license usage, re-licensing, and server configuration validation.

Measures ability to create, modify, and distribute SPC reports using InfinityQS templates. Includes understanding of KPIs (Cp, Cpk, Pp, Ppk), alarm summaries, box plots, histograms, and real-time dashboards. Also tests automation of reporting jobs, print/export preferences, and tailoring visuals for plant-level vs. executive insights.

Evaluates configuration skills for Data Management System (DMS) and Data Collection System (DCS) to define automated sampling plans, assign machine tags, set data collection intervals, and link with sensors or devices. Also includes managing conditional data inputs, setting tolerance rules, and configuring real-time alerts based on thresholds or sampling errors.

Tests proficiency in integrating InfinityQS with plant automation systems via OPC DA/UA servers and historian databases (e.g., OSI PI, GE Proficy). Includes tag mapping, live data stream validation, error handling, fallback logic, and manual override mechanisms. Also covers security protocols, data throttling, and historian archival strategies.

Assesses the use of Reusable Analysis Method Scripts (RAMS) to standardize SPC analytics across products, shifts, lines, or plants. Covers the creation of RAMS templates, assigning analysis rules (e.g., subgroup size, sigma limits), applying it across hierarchical data, and integrating results into reporting dashboards and alerts.

Measures ability to automate repetitive tasks such as report generation, data archiving, event-triggered data pulls, and process health checks using the Dynamic Scheduler. Includes chaining jobs, error recovery, condition-based execution, retry logic, and calendar/schedule-based triggers for daily or batch operations.

Evaluates ability to write and troubleshoot SQL queries used in InfinityQS data extraction and reporting. Topics include SELECT statements, joins, aggregates, WHERE clauses for filtering by process/part/date, and use of SQL in dashboards and control validation. Also assesses optimization of queries for large data sets and integration with external BI/reporting tools.

Assesses ability to integrate InfinityQS with MES, ERP (e.g., SAP), IoT hubs, and manufacturing data lakes using APIs, connectors, or data staging. Includes awareness of data harmonization, structure mapping, protocol compatibility (OPC UA, MQTT), and ensuring bidirectional sync of production and quality data.

Evaluates expertise in deploying InfinityQS across multi-site manufacturing environments with shared templates, global KPIs, data governance policies, and SPC maturity frameworks. Includes best practices in training, compliance (e.g., FDA CFR Part 11, ISO 9001), version control, and audit-readiness. Assesses leadership in standardizing analytics and aligning with strategic objectives.
