Trust me! I know what I’m doing

Have you ever had a near miss car accident?

It might be bizarre then to learn that I think I’m a good driver. Aren’t we all? But if I am a good driver, what lead to this remarkably stupid situation in which I only survived by sheer luck? Well, it was a culmination of factors, each of which by themselves did not cause me significant stress:

  • I worked as a fitness trainer. This means 5am starts.
  • I worked a hundred kilometers from where I lived. This I would leave home at ~3:30am.
  • I was at university, and this was coming to exams. Any spare time I would have, I’d elect to study and not sleep.
  • I was working several days in a row, and using caffeine as a stimulant to keep me awake. On that day, it failed.

But all added up together? Well, I ended up having a car accident.

That’s the point of this article. Bad things happen to all of us. Especially when we’re juggling a tonne of different things, up to and including things that we no longer entirely understand. These days, I work as a software developer, specialising in the deployment and management of e-commerce software. Guess what? Bad things still happen.

They’re different, though. Instead of having car accidents, something will break in a client system. Some clients turn over massive amounts of cash, and such a breakage will cost 10’s of thousands of Euros. They’ll lose client trust, customer trust and massively increase developer stress as they attempt to hastily repair the system to the best of their ability. If they’re lucky developers or happen to have an experienced colleague, it’s often not that bad — between 5 and 10 minutes of downtime, and we’re able to restore a system to some normality.

However, in both cases — the car accident and the broken system, the more important thing is to decide what happens next.

It’s extremely tempting to simply mark the issue resolved. I mean, the machine is back up right? And I survived my car accident. Hell, there wasn’t even any damage to the car. But such emergency response is exhausting, and the prospect of facing it again is simply more than I want to deal with. So, we undertake an exercise called a “blameless post mortem”.

The name derives from the macabre process of identifying how someone died by examining their body; also known as an autopsy. In the same process, it’s good to take the time and try and understand the circumstances that arose this situation, so they can be addressed and we can live less stressful lives in future. Our current template is characterised by the following sections:

  • Abstract (short summary)
  • People (the list of people in the article)
  • Timeline (a list of the events that occurred before the incident and that were taken to resolve it)
  • Impact (a list of the problems that the incident caused)
  • Contributing Factors (a list of the things that might have contributed)
  • Authors (The people who helped write the post mortem)
  • Thanks (Acknowledgement of the help of others)

The goal of these is to take emergency incidents and learn from them, so they can be avoided in future. As an example, let’s do a post mortem on my car accident.

Post Mortem of Car Accident, 2010–01–01


This post mortem requires follow up in 30 days ${DATE + 30}



Casual Factors

  • Unreasonable work schedule (Resolved. Found new employment)
  • Long distance between work and home (Resolved. Found employment closer to home)
  • Too many commitments (Resolved. Terminated university)
  • Caffeine abuse (Unresolved)




The process of learning is a continual one. But by carefully inspecting our failures, we can grow and learn and be safer and more secure in future.
