| Term | Description |
|---|---|
| Availability (A) | One of the three OEE components. Measures the proportion of planned production time during which a machine is actually running. |
| Cause and remedy | The system's explanation of why an event occurred and how it can be corrected. This may be shown in AI-generated help popups or instruction views (if available). |
| KPI (Key Performance Indicator) | A measurable value that represents how effectively a machine or process is performing. Common KPIs include OEE, Performance (P), Availability (A), and Quality (Q). |
| NOK (Not OK) parts | Defective or rejected parts in production. Shown in scrap views and used in quality calculations. |
| OE | Overall equipment effectiveness. In some contexts, OE is used interchangeably with OEE. |
| OEE (Overall Equipment Effectiveness) | A composite metric measuring overall manufacturing productivity. Calculated from Performance x Availability x Quality. |
| OK parts | Units produced that meet quality standards. Used in quality calculations (OK / (OK + NOK)). |
| Pareto principle (80/20 rule) | Used in Pareto charts to highlight the top contributors (often the "top 80%") to downtime, warnings, errors, or scrap. |
| PPM (Parts per minute) | A measure of production speed. |
| Performance (P) | An OEE component measuring how fast the machine runs compared to its ideal speed. |
| Quality (Q) | An OEE component representing the ratio of good parts (OK) to total produced parts (OK + NOK). |
| SOP (Standard Operating Procedure) | Formal process documentation defining how to perform specific tasks or handle certain faults. SOPs may be linked from instructions (if available). |
| Widget | A reusable UI element on a dashboard (for example KPI Cards, a Pareto chart, or a machine status timeline). Each widget provides a specific visualization or interaction type. |
