For a deeper look from the systems engineering side, check out http://mit.edu/psas, specifically the book-length treatment in “Engineering a Safer World”.
For applications of similar ideas to cloud software and devops-style environments, https://www.kitchensoap.com/2012/02/10/each-necessary-but-on... is also helpful!
