1. <section> <h2>Purpose</h2> <p>This specification defines a simple, action-focused operator dashboard wireframe and a companion alert-rule set designed to give operators the information they need to act quickly while minimizing unnecessary interruptions and alarm fatigue.</p> <h3>Design Principles</h3> <ul> <li>Action-first: show what an operator can do now, not every possible datapoint.</li> <li>Clarity over completeness: surface only essential KPIs and the top-3 active alerts.</li> <li>Minimize noise: suppress, group, and prioritize alerts so operators see only what matters.</li> <li>Accessible & local: high-contrast visuals, touch-friendly controls, and no dependence on color alone for meaning.</li> <li>Traceable: every alert should include required metadata so follow-up and analytics are possible.</li> </ul> <h3>Wireframe — Core Regions</h3> <ol> <li><strong>Header / Job Line</strong> <p>Machine/Cell name, current job/order number, part number, quantity required vs completed, current shift and operator name. Include a clear progress bar (percent complete) and estimated time to completion.</p> </li> <li><strong>Essential KPIs (prominent, at-a-glance)</strong> <ul> <li>OEE (short-term window, e.g., last 60 min)</li> <li>Current cycle time vs target</li> <li>Throughput / parts per hour</li> <li>First-pass yield / scrap rate (recent batch)</li> <li>Machine state (RUN / IDLE / STOPPED / MAINT)</li> </ul> </li> <li><strong>Top-3 Alerts</strong> <p>Only the highest-priority alerts should occupy this area. Each alert card contains: severity badge, concise title, time since triggered, one-line suggested immediate action, and action buttons (Acknowledge, Contain, Escalate).</p> </li> <li><strong>Simple Root-cause Hints</strong> <p>For each active alert show 1–2 actionable hints (e.g., “Check feed sensor alignment” or “Verify tooling clamp torque”). Keep language prescriptive and short.</p> </li> <li><strong>Action Buttons</strong> <p>Contextual buttons: Acknowledge, Contain (apply local fix), Pause Job, Call Maintenance, Log RCA. Buttons should trigger small modals or forms that capture minimal required info (see Alert fields below).</p> </li> <li><strong>Secondary Panel</strong> <p>Historical trend sparkline for key KPI, operator notes, and quick links to SOPs / troubleshooting guides for the current job.</p> </li> </ol> <h3>Layout & Visual Rules</h3> <ul> <li>Use a single-column central panel for KPIs and alerts; secondary info can be collapsed or on a right-side panel.</li> <li>Limit dashboard density: avoid more than 6 prominent elements on the main screen.</li> <li>Color: reserve red for critical, amber for warning, green for normal. Use icons and text labels in addition to color.</li> <li>Font sizes: KPIs large enough to read from 3–6 feet depending on shop layout. Action buttons must have minimum touch targets suitable for gloves.</li> <li>Sound & vibration: audible or haptic signals only for critical alerts; other severities should be visual-only by default.</li> </ul> <h3>Recommended Data Refresh Rates</h3> <ul> <li>Machine state and critical alarms: 2–5 seconds (near real-time).</li> <li>KPI aggregates (OEE, throughput): 15–60 seconds.</li> <li>Trend updates: 30–60 seconds.</li> </ul> <h3>Alert Rules — Overview</h3> <p>Alerts are governed by severity tiers, required metadata, suppression/debounce windows, grouping logic, and recommended operator responses. Design rules to avoid repeated transient notifications and to make escalation meaningful.</p> <h4>Severity Tiers (suggested)</h4> <table> <thead> <tr><th>Severity</th><th>Meaning</th><th>Example</th><th>Operator Expectation</th></tr> </thead> <tbody> <tr><td>Informational</td><td>Non-urgent status or advisory</td><td>Tooling approaching scheduled replacement</td><td>Note; no immediate action required</td></tr> <tr><td>Warning</td><td>Condition may degrade output or cause delay</td><td>Cycle time 20% slower than target</td><td>Operator should investigate and apply local corrective steps</td></tr> <tr><td>Critical</td><td>Immediate stop or safety risk; requires acknowledgement</td><td>Machine stopped with error code; safety interlock open</td><td>Immediate action, acknowledge, and escalate if not resolved within SLA</td></tr> </tbody> </table> <h4>Required Alert Fields (every alert payload must include)</h4> <ul> <li>alertId (unique)</li> <li>timestamp</li> <li>source (machineId / cellId)</li> <li>severity</li> <li>alertCode or name</li> <li>briefDescription</li> <li>suggestedImmediateAction (1–2 lines)</li> <li>context (current job/order, partNumber, batchId)</li> <li>reproducibilityHint (if available)</li> </ul> <h4>Suppression & Debounce Rules</h4> <ul> <li>Debounce short transient signals: require condition to persist for X seconds before first alert. Suggested default: 10–30s for warnings, 2–5s for critical machine stops.</li> <li>Suppress repeat alerts for the same alertId: do not re-alert within the suppression window once acknowledged. Suggested suppression windows: Informational 60s, Warning 5 min, Critical until acknowledged or cleared.</li> <li>Group related alerts into a single composite alert when they originate from the same root cause (e.g., power failure causing multiple machines to stop).</li> </ul> <h4>Escalation & SLA</h4> <ul> <li>Define escalation SLA per severity (e.g., Critical escalate to maintenance within 5 minutes if not acknowledged; Warning escalate to supervisor within 30 min if unresolved).</li> <li>Escalation actions should create an audit trail (who acknowledged, when, what actions were taken).</li> </ul> <h4>Operator Response Templates</h4> <p>When an operator taps an action button, open a minimal modal that captures:</p> <ol> <li>Action taken (select: Acknowledge, Contain, Pause, Escalate)</li> <li>Short note (required for Critical; optional for Warning)</li> <li>Time to resolution (filled later by maintenance or auto-updated)</li> </ol> <h3>Examples</h3> <p>Sample alert card text:</p> <blockquote> <p><strong>Critical:</strong> Machine 12 stopped — Error E23 (Hydraulic pressure low). <em>Suggested immediate action:</em> Verify hydraulic reservoir level and call maintenance. Acknowledge to notify team.</p> </blockquote> <h3>Integration-ready Alert Payload (example)</h3> <pre>{ "alertId": "A-20260811-0001", "timestamp": "2026-08-11T09:23:17Z", "source": "machine-12", "severity": "critical", "alertCode": "E23", "briefDescription": "Hydraulic pressure below threshold", "suggestedImmediateAction": "Stop feed, check reservoir level, call maintenance", "context": {"jobId": "JOB-4521", "part": "PN-1234", "batchId": "B-998"}, "reproducibilityHint": "Occurs after warm-up" }</pre> <h3>How this reduces alarm fatigue</h3> <ul> <li>Show only top-3 alerts and aggregate related notifications to avoid list overload.</li> <li>Debounce transient signals before presenting them.</li> <li>Require contextual suggested actions so operators can act quickly without opening manuals.</li> <li>Use suppression windows and acknowledgment requirements to prevent repeated alerts from the same root cause.</li> </ul> <h3>Accessibility & Safety Notes</h3> <ul> <li>Do not rely on color alone—use icons and text labels for severity.</li> <li>Ensure minimum button sizes for gloved use and clear spacing to prevent accidental taps.</li> <li>For safety-critical alerts, require a brief operator acknowledgement and an automatic pager/escalation if not acknowledged in the SLA window.</li> </ul> <h3>Operational Guidance for Deployment</h3> <ol> <li>Begin with a single line or cell pilot. Tune debounce and suppression windows there before roll-out.</li> <li>Collect operator feedback weekly during the first month to adjust message language, hint usefulness, and thresholds.</li> <li>Instrument analytics that capture alert frequency, acknowledgment times, and false-positive rates so rules can be tightened over time.</li> </ol> <h3>Appendix — Quick Checklist for Implementers</h3> <ul> <li>Define machine and job context mappings so alerts carry job-specific context.</li> <li>Configure severity-to-action mappings and SLA rules.</li> <li>Provide links to SOPs and troubleshooting guides for each common alert code.</li> <li>Expose minimal operator response form fields and persist responses for audit and learning.</li> </ul> </section>
