This module lays out these standards for safety critical systems: $$The process of building software for safety critical systems takes much longer and is much more expensive than for $[$other$]$ high quality systems $[$because$]$: $(1)$ it requires highly trained and experienced professionals who work closely with safety and systems engineers to ensure that the entire system operates in a safe manner; $(2)$ extreme measures must be taken to identify and remove software defects starting at the earliest stages of software development; and $(3)$ a great deal of effort must be spent identifying what can go wrong, the likelihood and consequences of such occurrences, and identifying how these risks can be a averted, mitigated, or detected so users can be warned. Two key issues software developers face when developing safety$-$critical systems are $(1)$ how to weigh cost and ease of use issues versus safety and product appeal, and $(2)$ how to decide when sufficient software testing has been done.$$

Do you think Boeing observed these standards in the case of the $737$ Max?

What do you think Boeing$$s defense will be in the various lawsuits it faces and in the court of public opinion? What should its defense be$?$

This module points out that striving for ethical decision making is just good business. An old proverb goes like this: $$For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the message was lost. For want of a message the battle was lost. For want of a battle the kingdom was lost$.$

Can Boeing$$s decision making be called unethical? Could it possibly result in the loss of their kingdom?
