New York Times article on Boeing's handling of the design of the 737 Max airplane; it's not a pretty picture.

The New York Times has published an article describing certain aspects of the process that led to the design and manufacture of the Boeing 737 Max airplane, the model recently involved in several crashes, which paints a really bad picture for the company.  If the article is accurate, and the statements can be proven in court, the picture is one of negligence, if not intentional or reckless, management of the design process which could be used against the company in a product liability case.  The article is called "Boeing Built Deadly Assumptions Into 737 Max, Blind to a Late Design Change" and you can read it in full here, but here is the gist of it:
The fatal flaws with Boeing’s 737 Max can be traced to a breakdown late in the plane’s development, when test pilots, engineers and regulators were left in the dark about a fundamental overhaul to an automated system that would ultimately play a role in two crashes.
A year before the plane was finished, Boeing made the system more aggressive and riskier. While the original version relied on data from at least two types of sensors, the final version used just one, leaving the system without a critical safeguard. In both doomed flights, pilots struggled as a single damaged sensor sent the planes into irrecoverable nose-dives within minutes, killing 346 people and prompting regulators around the world to ground the Max.
But many people involved in building, testing and approving the system, known as MCAS, said they hadn’t fully understood the changes. Current and former employees at Boeing and the Federal Aviation Administration who spoke with The New York Times said they had assumed the system relied on more sensors and would rarely, if ever, activate. Based on those misguided assumptions, many made critical decisions, affecting design, certification and training.
“It doesn’t make any sense,” said a former test pilot who worked on the Max. “I wish I had the full story.”
While prosecutors and lawmakers try to piece together what went wrong, the current and former employees point to the single, fateful decision to change the system, which led to a series of design mistakes and regulatory oversights. As Boeing rushed to get the plane done, many of the employees say, they didn’t recognize the importance of the decision. They described a compartmentalized approach, each of them focusing on a small part of the plane. The process left them without a complete view of a critical and ultimately dangerous system. 
The company also played down the scope of the system to regulators. Boeing never disclosed the revamp of MCAS to Federal Aviation Administration officials involved in determining pilot training needs, according to three agency officials. When Boeing asked to remove the description of the system from the pilot’s manual, the F.A.A. agreed. As a result, most Max pilots did not know about the software until after the first crash, in October.
