What is Integrated Systems Testing (IST) primarily intended to do?

Integrated Systems Testing (IST) is fundamentally designed to assess how various systems within a facility, such as HVAC, lighting, and security, work together under different operational conditions and loads. This type of testing allows for the evaluation of system interactions, performance under peak conditions, and overall functionality of integrated systems, ensuring that they operate as intended when put to actual use.

While assessing the physical structure of a building or providing training for staff are important aspects of facility management, they do not directly relate to the primary purpose of IST. Additionally, routine maintenance checks focus on keeping systems operational rather than testing their integrated performance in real-world scenarios. IST plays a crucial role in verifying that all systems can perform optimally when used together, which is essential for mission-critical operations.
