There are many resources available on QSR, design controls and standards, etc; but there is a gap in understanding how these protocols should be designed to follow these regulations.

Let’s say I am designing a PCB and have to write a protocol to test it. I would include measuring voltages and current at different stages.

But there is much more to consider, even before I plug in the device (like shorts and loose solder connections). Many companies have a team to take care of this, but in a start-up that may not be practical.

My question: What's a good approach when just starting out in protocol design?

Polyolefins have been shown to be safe alternatives to PVC's widely reported risks.

However Polyolefin films make up only a small percentage of liquid tight medical bags in the US with shapes and fitments.

Is it because of the sizable investments already made, or not knowing how to make with Polyolefins in scale?
