A live SPC dashboard shows quality data on a screen as it is measured: readings against specification limits, control charts against control limits, and capability indices such as Cp, Cpk and Ppk. It runs unattended on a TV beside the line, or in a browser at a desk, and refreshes without anyone pressing a button.
Zometric Live Dashboards read the plant's quality data: variable readings (individuals and subgroups), defective and defect counts, and each scheme's stability and capability verdict. A scheme is one characteristic measured on one line, machine and product. Widgets sit on a 24-column grid. A TV dashboard is a fixed canvas that never scrolls, and its slides rotate. A PC dashboard is a scrolling grid. Both are built by dragging and resizing widgets from a catalog of 20 data-backed widget types.
The dashboard does not recalculate SPC. Control limits, run-rule results and Cp, Cpk and Ppk are shown exactly as the source calculated them, so the screen on the wall agrees with the SPC report. The dashboard only judges presentation: whether a reading is in spec, in the warning band or out of spec, and whether a scheme reaches the capability target each widget sets (1.33 by default, on Cpk or Ppk).
Six things quality and production teams say about the screens on their shopfloor, and what changes when the screen reads live SPC data.
From connecting the data source to the TV on the wall, every step happens in the browser.
Setup · Data source
Under Settings, Data sources, enter a URL and token for each of five functions: work units, shifts, schemes, quality records and capability. Each URL is tested against its published contract and is saved only if the test passes.
Setup · Work units
Discover the work units the source serves and sync its shift pattern. Schemes, with their spec and warning limits, are synced for each work unit and refreshed again when they go stale.
Build · Dashboard
Choose a TV screen, where slides rotate on a fixed canvas, or a PC grid that scrolls. You can also copy any dashboard in the tenant and point its widgets at this work unit's schemes.
Build · Widgets
Pick widgets from the catalog, then drag and resize them on the 24-column grid. Set each widget's own scope: schemes, lines, equipment types or a filter, its capability target, and display settings such as text size and colour intensity. The panel previews the change as you make it.
Configure · Window and refresh
Choose how far back the dashboard looks: the last few shifts, a rolling number of days, weeks or months, or a fixed date range. Then choose how often it refreshes. A fixed range that lies fully in the past stops refreshing, because its data cannot change.
Release · Publish
Every edit autosaves to a draft that viewers never see. Publishing releases it. A dashboard can be visible to everyone in the tenant or only to selected groups.
Run · TV wall
Slides rotate at the duration set for each one, with a progress bar showing when the screen will change. The header shows the data window and the last and next refresh times. Anyone at the screen can pause or step through the slides.
Share · Export
Users with the export permission download every slide as a PDF or PowerPoint file, rendered at 1920 × 1080 with one slide per page.
Each capability is tied to a decision your team is already trying to make.
Pick widgets from a catalog of 20 and drag and resize them on a 24-column grid, on rotating TV slides or a scrolling PC page. Edits autosave to a draft that viewers never see until you publish.
Each dashboard pulls fresh data every 30 seconds by default, or at any preset from 5 seconds to 10 minutes. The header shows the last and next refresh times, and a past fixed date range stops refreshing because it cannot change.
Every characteristic, line and product against its spec limits on one board, marked in spec, warning or out of spec. A current-shift reading outside spec is highlighted as an alarm.
Built for TVs left on for weeks: each widget fetches its own data, so one failure shows an error on that widget only while the rest keep updating, and the page reloads itself once a night at 03:00.
Control limits, run-rule counts and Cp, Cpk and Ppk are shown exactly as the SPC system calculated them, never recomputed, so the wall agrees with the SPC report.
The SPC quadrant matrix, capability KPI card and capability- and stability-gap worklists show which of hundreds of schemes need attention first, each against the target the widget sets (Cpk 1.33 by default).
Each card in the quality matrix shows the latest reading of one scheme in the current shift. If the shift has no reading yet, it shows the last recorded one, marked as the last run. The reading is out of spec if it falls below the LSL or above the USL. It is in the warning band if it falls outside the scheme's warning limits. If the scheme has no warning limits, the warning band is the outer 15% of the spec band on each side.
| Scheme | LSL | USL | Warning limits | Reading | Status |
|---|---|---|---|---|---|
| Moisture %, Line 1 | LSL2.00 | USL4.00 | Warning limits2.30 – 3.70 (15% rule) | Reading3.12 | StatusIn spec |

Live Dashboards read quality data. They do not write anything back.
Work units, shifts, SPC schemes with their spec and warning limits, readings, and each scheme's stability and capability verdict are read from the SPC system. Any other system can supply the same data by answering the same published contract.

A tour of Live Dashboards — building drag-and-drop TV and PC dashboards that show live SPC data on self-updating screens for the shopfloor.
| Zometric Live Dashboards vs spreadsheets and static reports on a TV | Spreadsheet, static report or generic chart page | Zometric Live Dashboards |
|---|---|---|
| Freshness | Updated when someone re-exports or reloads it | Refreshes on its own, every 30 seconds by default |
| SPC numbers | Control limits and Cpk retyped or recalculated in a sheet | Limits, run-rule counts and Cp, Cpk and Ppk shown exactly as the source calculated them |
| Before out of spec | Nothing until a value crosses a limit | Warning band from the scheme's warning limits, or the outer 15% of the spec band |
| Large screens | Pages scroll off the bottom or get cut off | Fixed 24-column canvas, rotating slides, and widgets that page instead of cropping |
| One bad feed | The whole screen fails | Only that widget shows an error, and the rest keep updating |
| Running for weeks | A browser tab nobody restarts | Reloads itself once a night at 03:00 local time |
| Who sees what | Anyone with the file or the link | Draft and published versions, with visibility by group |
| Meetings | Screenshots pasted into slides | Every slide exported to PDF or PowerPoint |
Five functions (work units, shifts, schemes, quality records and capability), each called by POST with a JSON body and its own token. Every contract is documented on the help page, and a URL is saved only after its answer passes the contract test.
Schemes and their limits are synced from the source for each work unit, and the shift pattern for the tenant. A scheme that stops appearing in the source is treated as retired and hidden.
Every slide of a dashboard is rendered at 1920 × 1080 and saved as one PDF page or one PowerPoint slide each.
Straight answers to the questions teams ask before a demo.
A live SPC dashboard shows quality data on a screen as it is measured: readings against spec limits, control charts against control limits, and capability indices such as Cp, Cpk and Ppk. Zometric Live Dashboards run unattended on shopfloor TVs as rotating slides, or in a browser on a PC, and refresh without anyone pressing a button.
Quality data: variable readings (individuals and subgroups), defective and defect counts, and each scheme's stability and capability verdict, for the work units and shifts the source defines. The dashboards read five functions from the source: work units, shifts, schemes, quality records and capability.
Every 30 seconds by default. Each dashboard can be set to 5, 10 or 30 seconds, or 1, 2, 5 or 10 minutes. A dashboard fixed to a date range that lies fully in the past stops refreshing, because its data cannot change.
No. Control limits, run-rule counts and Cp, Cpk and Ppk are shown exactly as the source calculated them, so the dashboard agrees with the SPC report. A widget only compares the index with its own capability target, 1.33 on Cpk by default, and prints that rule on screen.
A TV dashboard is a set of slides on a fixed 24-column canvas that never scrolls. Slides rotate, 15 seconds each by default. A widget with more data than fits pages itself, and the slide stays up until every page has been shown. Several charts can also share one page.
Yes. Editors pick widgets from a catalog and drag and resize them on a 24-column grid, on TV slides and on PC grids. Each widget is then configured in a panel that previews the change, and nothing reaches viewers until the dashboard is published.
Yes. A dashboard is visible either to everyone in the tenant or only to selected groups, and viewers only ever see published dashboards. Editing, exporting, deciding who sees which dashboard, and managing data sources are separate permissions.
Yes, with the export permission. Every slide is rendered at 1920 × 1080 and saved as one PDF page or one PowerPoint slide each.
