How is the three-checks and four-fixes approach applied in each specific step of the process?

Three Checks: Check for any omissions in the design, examine the quality of the work and any potential hazards, and verify the amount of work that remains unfinished. Four Fixes: Determine the tasks, assign personnel, set deadlines, and establish measures to ensure completion within a specified time frame. For a system, it is necessary to check for any design flaws – for example, whether gas-shut valves should be used instead of gas-open valves from a process safety perspective. It is also important to ensure that construction follows the installation specifications: check the installation direction of control valves, whether the pressure tapping points meet the requirements, whether the electromagnetic flowmeter has sufficient straight pipe sections, whether the metal float is vertical, and whether the protective tubes are properly installed, among other things

No one is paying attention? ? ? ? Go through the whole process from start to finish. . . . Are the valves present? What about the instruments? What is the installation direction? Are there enough bolts? Are the pipeline valves easy to operate? There’s so much to consider; I know too little. Please tell me so I can organize everything properly.
