"I design a cell to not fail and then assume it will and then ask the next 'what-if' questions," Sinnett said. "And then I design the batteries that if there is a failure of one cell it won't propagate to another. And then I assume that I am wrong and that it will propagate to another and then I design the enclosure and the redundancy of the equipment to assume that all the cells are involved and the airplane needs to be able to play through that."

—Mike Sinnett, Boeing's 787 chief project engineer

Isn't the point of the article that Boeing may not have actually done at least the first two steps (design cell not to fail, prevent failure of a cell from causing battery problems)?

I am confused.

It's the point of the problem, anyway.

SInnett is probably a very good designer, but the battery design was outsourced.
