How I Learned to Stop Worrying & Love Misery • Gil Tene • YOW! 2019
Measure system success by focusing on misery, not success, to gain a more accurate picture of performance and uncover hidden problems.
- Percentiles are often used as a way to measure the success rate of a system, but they can be misleading.
- The speaker suggests focusing on measuring misery instead of success, as it can provide a more accurate picture of how a system is performing.
- Traditional ways of measuring success can lead to a false sense of accomplishment, as small improvements may not actually make a significant difference.
- The speaker argues that it’s more important to measure and understand the negative experiences of a system, as this will help to improve its overall performance.
- The speaker also suggests that the term “nines” (e.g. 99.9% uptime) is often used as a way to make a system sound better than it actually is.
- A “rainbow at the end of a tunnel” refers to the idea that even the most complex and difficult systems can be improved over time, through the use of data and metrics.
- A “trash compactor” is a humorous metaphor for the way that complex systems can sometimes be simplified and improved.
- A “Witch Doctor” is a humorous term used to refer to someone who is trying to fix a complex system without truly understanding it.
- The speaker suggests that it’s important to recognize when a system is being “beaten up” and needs to be improved.
- The concept of “coordinate admission” refers to the idea that different parts of a system may experience different times of high load, which can affect the overall performance of the system.
- The speaker argues that it’s important to focus on the misery of a system, rather than just its success.
- A “SPOT” (Symptoms, Possible Causes, Observations, Theory) is a framework used to analyze and improve a system.
- The speaker suggests that it’s important to take a step back and look at the system as a whole, rather than just focusing on individual components.
- “Duct Tape and Garage” is a humorous term used to refer to the idea that complex systems can sometimes be simplified and improved by using creative solutions.
