When a new system has been assembled built up and is ready for testing the first to do is?

When a new system has been assembled and is ready for testing, the first step is to conduct a thorough inspection to ensure all components are correctly installed and functioning as intended. Next, perform initial power-on tests to verify that the system powers up without issues. After that, execute basic functionality tests to confirm that key features work properly before proceeding to more detailed and rigorous testing phases. This initial assessment helps identify any immediate problems that need to be addressed.
