  • • Elite: Deploy multiple times/day, less than 1hr lead time, less than 1hr recovery
  • • High: Deploy weekly-daily, less than 1 day lead time, less than 1 day recovery
  • • Medium: Deploy monthly-weekly, 1 week-1 month lead time
  • • Low: Deploy less than monthly, greater than 6 months lead time

Technical Debt Calculator

Estimates the hidden costs of technical debt based on industry research showing teams typically spend 20-40% of their time dealing with technical debt.

Incident Cost Calculator

Calculates the true cost of system outages including direct revenue loss, team response costs, and customer impact multipliers.

Note: These tools provide estimates based on industry benchmarks and research. Use them as starting points for discussions and improvement initiatives within your organization.
