Performance verification ensures your system is operating properly.

Performance verification is the process of inspecting the system either prior to startup or anytime after it has been commissioned to verify its operating characteristics and correlate them with expected results.

  • To secure final funding
  • As a basis of warranty claims
  • To provide a baseline, useful for future comparisons and troubleshooting
  • To determine degradation over time
