Without Banshee (per campaign)
campaignDurationWeeks = affected / 50

scripting_hours = 16 + (affected × 0.05)
  // 16 hr baseline + 3 min/repo for edge cases
  // Spotify's "simple" Maven updater → 20,000+ LOC (Spotify Engineering blog, 2024)

pr_lifecycle_hours = affected × (minutes_per_pr / 60)
  // User-provided: your avg time chasing each PR to merge

status_tracking_hours = campaignDurationWeeks × 2
  // 2 hrs/week on spreadsheets and leadership updates (internal estimate)
With Banshee (per campaign)
scripting_hours = 4 + (affected × 0.01)
  // YAML spec vs custom scripting → ~75% reduction

pr_lifecycle_hours = affected × (minutes_per_pr / 60) × 0.15
  // 85% reduction via automated reminders, auto-merge, escalation
  // Grounded in Spotify's 70% lifecycle figure + automated follow-up
  // 37% bot PR merge rate → ACM research

status_tracking_hours = campaignDurationWeeks × 0.2
  // 90% reduction — dashboard replaces spreadsheets (internal estimate)
Annual savings
hours_saved_per_year   = (total_before - total_after) × campaigns_per_year
dollars_saved_per_year = hours_saved_per_year × hourly_rate
Migration time
weeks_before = affected / 50   // ~50 PRs merged/week manually
weeks_after  = affected / 400  // parallel gradual rollout + auto-merge
Payback period (internal estimate)
// Pricing tiers (matching bansheeapp.com/pricing):
//   ≤5 repos   → $0/yr (free)
//   ≤50 repos  → $4,800/yr + $20/repo/mo above 25
//   ≤500 repos → $18,000/yr + $12/repo/mo above 100
//   >500 repos → $40,000/yr (floor)

payback_campaigns = ceil(annual_cost / (dollars_saved / campaigns_per_year))
// min 1 campaign. If savings < cost → "not cost-justified at this scale"
