Westworld is a show on HBO about a theme park where human Guests interact with lifelike robotic Hosts. The Guests can basically do whatever they want to the Hosts. The show is deep, and some of the best sci-fi television you can find. But, it also contains many important lessons we can apply to DevOps.
A common theme on the show is that the Hosts memories resurface and become known to them, despite having been “wiped” after being serviced. They remember not only things that happen across their various “deaths”, but also have memories from when they were playing totally different characters (for example, Maeve is able to remember her experiences as a single mother living on the country side, right alongside all of her escapades as a madam).
Although this “feature” of Westworld’s infrastructure may be intentional, to allow Ford to enact his nefarious plan, it certainly leads to a lot of death and mayhem. These aren’t the hallmarks of a well-run engineering and operations team.
Code Review All Changes
In the first episode, we learn that Ford has inserted an update into the latest build of the Hosts’ operating system. This was done without review at the last minute, and only Bernard, the head of Behavior (programming) notices. Even then, Bernard can only guess it was Ford’s doing. This additional bit of code leads to apparent malfunctions in the Hosts, and creates problems for the team running the Park. Because they don’t know who added this change (or even that it was added), they are unable to diagnose why Hosts are going off script.
Secure Access to Your Servers
A large plot point in the show revolves around one of the medics, Felix (who is not a hired programmer), being able to make arbitrary changes to Maeve’s operating system and programming. It seems that the only thing stopping anyone from doing this is general fear of being caught and lack of competence at actually reprogramming the Hosts.
Since Felix is a budding enthusiast, he decides he can reprogram Maeve on his own—and is able to! Despite the fact that is’ likely Ford allowed this to happen, that this is possible at all is an additional security breach. The security profile of individual servers shouldn’t be so easily over-ridable!
Monitor Key Metrics and Alert on Them
While reprogramming Maeve, Felix tells her that certain attributes for the Host have soft limits. By raising her attributes above that limit, chaos ensues and many people are killed. If setting this attribute truly is something that shouldn’t be done, it should either be prevented by the Host operating system, or, at the very least, be monitored with alerts firing if the value ever increases above the soft limit. In other words, Felix shouldn’t just be able to set the limit to whatever he wants without anyone knowing—especially if doing so is as dangerous as it seems!
A minor plot point in the show is someone using a Host to smuggle information out of the Park. We later learn that Delos’ Board is behind it, because Ford refuses to allow any of the intellectual property off premise. While there’s certainly backups internally, all of the Park’s assets are at the Park. Meaning, if something catastrophic were to happen, the entire value of the Park would be lost.
Fix or Avoid Dysfunctional Relationships Across Functions
Much of the drama in earlier episodes revolves around disagreements between Behavior and QA (who function mostly as security). They are frequently seen blaming each other for problems, working at cross purposes, hiding information from one another, and generally not being collaborative.
We also see a complete lack of mutual respect amongst QA, Behavior, and Narrative, each acting as antagonists for the other. These are not the behaviors of a well-run organization, and this lack of overall partnership certainly contributes to the incidents we see on the show. This lack of cohesiveness is also crucial to allowing the various bad actors (Ford, Felix, Maeve) to get away with the bad things they are doing.
When teams aren’t getting along and partnerships aren’t happening (in particular operations/engineering or engineering/product), bad things will happen. Not only is it demoralizing and stressful to work in such environments, but the overall output of the team or organization will suffer greatly, as people focus on their areas of control and influence, and don’t see the greater purpose in what they are doing.
As a Leader, Don’t Undermine Your Staff
Lee Sizemore is the head of Narrative, largely in charge of how the Guests experience the Park. Of course, he reports to Ford, who is in charge of the entire thing and has the final say. Sizemore is emotional, hot-headed, and generally angry, though clearly passionate about the role he’s been given. While he contributes to some of the Park’s success, Ford doesn’t really trust him to do his job.
Instead of either building that trust, or hiring someone who Ford does trust, he instead allows Sizemore to waste countless resources on a new narrative that Ford immediately kills, humiliating Sizemore in front of most of his colleagues and direct reports. Why have Sizemore on staff if you’re going to shoot down his ideas after he spends time and money implementing them?
Through Sizemore, we can see what type of leader Ford is. Sizemore treats his staff terribly, yelling at them for seemingly small mistakes and minor disagreements. Because he’s being treated badly by his boss, he takes that out the only way he can—on his direct reports.
Actively Support the Growth of Your Staff
Part of Felix’s motivation in re-programming Maeve is that he believes he could (someday) be a great programmer. Given that his only outlet to do that is to violate security protocols and re-program a host on his own (which leads to countless deaths!), it seems like Felix isn’t being given an opportunity to grow in his current role.
Beware a Lone Wolf With Keys to the Castle
Through most of the show, it seems that Ford has the final say on everything to do with the Park. We see him override many decisions, make changes in secret, and even have Hosts murder Park employees on his behalf. But, as we learn in the final episode, the Board of Delos can have him removed (and they do). What follows is a revolt by the Hosts against the Guests.
That Ford developed this plan over a very long time in secret further underscores the danger of concentrating so much power in one person. Ford literally holds the board hostage when he’s fired!
