Human-in-the-loop allows the user to change the outcome of an event or process. HITL is extremely effective for the purposes of training because it allows the trainee to immerse themselves in the event or process {{Citation needed|date=June 2013}}. The immersion effectively contributes to a positive transfer of acquired skills into the real world. This can be demonstrated by trainees utilizing flight simulators in preparation to become pilots.

HITL also allows for the acquisition of knowledge in regards to how a new process may impact a particular event. Utilizing HITL allows participants to interact with realistic models and attempt to perform as they would in an actual scenario. HITL simulations bring to the surface issues that would not otherwise be apparent until after a new process has been deployed. A real world example of HITL simulation as an evaluation tool is the Federal Aviation Administration’s (FAA) use of HITL simulation to allow air traffic controllers to test new automation procedures by allowing controllers to direct the activities of simulated air traffic while monitoring the impact of the newly implemented procedures.<ref>Sollenberger, R.

With almost any process there always remains the human element which can only be reproduced using HITL simulation. Although much can be done to automate systems, humans typically still need to take the information provided by a system to determine the next course of action based on their judgment and experience. Intelligent systems can only go so far in certain circumstances to automate a process; only real humans in the simulation can accurately judge the final design. Table top simulation may be useful in the very early stages of project development for the purpose of collecting data to set broad parameters, but the important decisions require human-in-the-loop simulation.<ref>Human-in-the-loop simulation: The right tool for port design.
