Which department is most likely involved in the commissioning process?

The commissioning process typically involves the engineering department because commissioning is primarily concerned with ensuring that systems perform as intended. During this phase, engineers are responsible for coordinating the design, installation, and verification of the systems and equipment in a project. Their technical expertise is crucial in validating that all components work correctly and meet the project specifications.

Engineers also oversee the final testing and inspection of systems to confirm that everything operates efficiently and safely before the project is officially completed and handed over. They play a vital role in troubleshooting and resolving any issues that arise during commissioning, making their involvement essential in this context. Other departments, while they may have roles in related areas of project management, do not directly engage with the technical validation required in the commissioning process to the same extent as engineering.
