It's pretty easy, just hire one subject matter expert (SME) on submarines and listen to them.

So many problems with this scheme, though. No rigorous test (depth, survival, atmosphere), lack of SMEs, carbon fiber hull, failed to learn lessons from aviation (don't lock people in a room that can burn), lack of ventilation, failure to provide emergency breathing, no voice comms, and finally the comms loss during testing that was normalized as operating procedure.

All you'd have to do is not make one of those mistakes, and you'd be doing a better job. These are all issues that are solved on US Navy subs, where we train hundreds of people every year to work on and retire just as many. You don't need to know all these systems, though, just find a retired sub chief and have them walk you through the safety systems.

One thing I've picked up working in software, is that you can enter new domains with relative ease if you just align yourself with experts, and at least listen to their advice. This isn't something that happened on the sub, and I'd be surprised if it ultimately didn't contribute to the total vehicle loss.

That "retired sub chef" mais not be inspirational enough.
