In 2010, the My Little Pony franchise was rebooted with the animated show My Little Pony: Friendship is Magic . The combination of accessibility to children with the sophisticated themes the show tackled garnered a following that cut across ages. I was swept up in the wave and discovered there is a lot to learn about DevOps from the show.
Discovering technical debt
The show begins with Twilight Sparkle reading obscure documentation, only to realize that Equestria, where the show is set, is due to suffer a calamity. Though someone named Nightmare Moon has been imprisoned for a thousand years, there is a prophecy she will return.
Lesson 1: Technical debt matters.
Nightmare Moon is a perfect stand-in for technical debt. Document it. Pay attention to the signs of risk no matter how infrequently they occur. Have a plan to resolve it.
Twilight Sparkle goes to her manager with the news, only to be told that it is not a current priority. She is sent to Ponyville to prepare for the coming celebration, instead.
Lesson 2: Communication with management is key.
Twilight Sparkle communicated her priority (the risk of technical debt) but did not convince her management that it was more important than the celebration (of the next release or a new customer).
We all need to make clear what the business case is for resolving critical issues. It is also not straightforward to explain technical debt in business terms. If management does not agree on the severity, find new ways to communicate the risk, and team up with others who speak that language.
When technical debt becomes an outage
More DevOps resources
Lesson 3: Few are the issues that can be resolved by one person.
When facing an outage, reach out to other people with complementary skills who can help you. It is best if they are different than you: different backgrounds leads to differing perspectives, and that can lead to better problem-solving.
Lesson 4: When resolving an outage, honest communication is key.
Throughout the struggle against the eternal night, the Mane Six have to speak openly and honestly about what's not working. Their blameless communication is part of problem-solving.
Lesson 5: When resolving an outage, kindness to yourself and to others is crucial.
Though tempers flare hot in the land of Equestria, we all benefit from coming back to working together.
Lesson 6: Laughter is important.
Even when everything comes crashing down, remember to take a break, drink a glass of water, and take a deep breath. Stressing out does not help anything.
Lesson 7: Be generous.
Even if you are not on-call right now, if your help is needed to resolve a problem, help out as you hope your colleagues will do for you.
Lesson 8: Be loyal.
An outage is not a time to settle rivalries between teams. Focus on how to collaborate and resolve the outage as a team.
Lesson 9: Though people skills are important, you have to understand the technology on a deep level.
Keep your skills sharp. Expertise is not only the ability to learn; it is knowing when that information is needed. Part of being an expert is practice.
Growing into a culture of continual improvement
After the issue is resolved, Princess Celestia realizes that the Mane Six are crucial to the long-term survival of Equestria, and tells Twilight Sparkle to stay in Ponyville and keep researching the magic of friendship.
Lesson 10: After an outage is resolved, conduct a review, take concrete lessons, and act on them.
I could go on, episode by episode, detailing lessons relevant for DevOps, but I will wrap up with one of my favorite ones. In the "Winter Wrap-Up" episode, all the ponies in Ponyville help in preparing for the spring. As per tradition, they do not use magic, leaving Twilight Sparkle to wonder how she can contribute. Eventually, she realizes that she can help by making a checklist to make sure everything is done in the right order.
Lesson 11: When automation is impossible or inadvisable, write a solid checklist, and follow it. Do not depend on your memory.
Twilight Sparkle and the Mane Six overcome great obstacles as a team, and now have a system to improve as a team.
A story of DevOps
This story reflects how many organizations slowly adopt DevOps. The transition from recognizing a fear of technical debt toward addressing it is not simple. With courageous leadership, teamwork, and a willingness to improve, all organizations can come out on the other side with a similar story to Twilight Sparkle and her friends.
