  assessment.setValue("risk_rating", rating)

  // Notes
  assessment.setValue("notes", assessmentData.notes)

  return assessment.insert()

Vendor Performance Scorecard

// Calculate vendor performance score (ES5 ONLY!)
function getVendorScorecard(vendorSysId) {
  var scorecard = {
    vendor_sys_id: vendorSysId,
    sla_performance: 0,
    ticket_metrics: {},
    risk_rating: "",
    overall_score: 0,
  }

  // SLA performance
  var slaMeasurements = new GlideAggregate("u_sla_measurement")
  slaMeasurements.addQuery("sla.contract.vendor", vendorSysId)
  slaMeasurements.addQuery("measured_date", ">=", gs.monthsAgo(12))
  slaMeasurements.addAggregate("AVG", "met")
  slaMeasurements.query()

  if (slaMeasurements.next()) {
    scorecard.sla_performance = Math.round(slaMeasurements.getAggregate("AVG", "met") * 100)
  }

  // Incident metrics
  var incidents = new GlideAggregate("incident")
  incidents.addQuery("vendor", vendorSysId)
  incidents.addQuery("opened_at", ">=", gs.monthsAgo(12))
  incidents.addAggregate("COUNT")
  incidents.addAggregate("AVG", "calendar_duration")
  incidents.query()

  if (incidents.next()) {
    scorecard.ticket_metrics.count = parseInt(incidents.getAggregate("COUNT"), 10)
    scorecard.ticket_metrics.avg_resolution = incidents.getAggregate("AVG", "calendar_duration")
  }

  // Latest risk assessment
  var assessment = new GlideRecord("vendor_risk_assessment")
  assessment.addQuery("vendor", vendorSysId)
  assessment.orderByDesc("assessment_date")
  assessment.setLimit(1)
  assessment.query()

  if (assessment.next()) {
    scorecard.risk_rating = assessment.getValue("risk_rating")
  }

  // Calculate overall score
  scorecard.overall_score = calculateOverallScore(scorecard)

  return scorecard

Example Workflow

// 1. Query active vendors
await snow_query_table({
  table: "core_company",
  query: "vendor=true^vendor_active=true",
  fields: "name,vendor_type,u_vendor_tier,contact",
})

// 2. Find expiring contracts
await snow_execute_script_with_output({
  script: `
        var expiring = getExpiringContracts(60);
        gs.info(JSON.stringify(expiring));
    `,
})

// 3. Get vendor scorecard
await snow_execute_script_with_output({
  script: `
        var scorecard = getVendorScorecard('vendor_sys_id');
        gs.info(JSON.stringify(scorecard));
    `,
})

Best Practices

1. Vendor Classification - Tier by importance
2. Contract Tracking - Monitor expirations
3. SLA Monitoring - Track performance
4. Risk Assessment - Regular evaluations
5. Performance Reviews - Quarterly scorecards
6. Documentation - Complete records
7. Compliance - Verify certifications
8. ES5 Only - No modern JavaScript syntax
