Integrated Systems Testing is sometimes referred to by what alternative commissioning level name?

• A. Integrated Systems Testing (IST)
• B. Level 2 (L2)
• C. Handoff to Commissioning (H2C)
• D. Substantial Completion

Answer: (A)

In commissioning, testing how all systems work together as one coordinated unit is essential to verify that interfaces function and performance meets requirements. This stage is commonly called Integrated Systems Testing, and teams often refer to it simply by its acronym IST. So the alternative commissioning level name you’ll see is Integrated Systems Testing (IST), meaning the same concept expressed as either the full term or its abbreviation. The other options describe different phases or milestones in the commissioning timeline and aren’t alternate names for this testing level.
