Etsy sellers are encouraged to explain about their mistakes and it can be conveyed through email. This process is called PSA where people send a list of mistakes they made and explains how they committed the mistakes, through public emails.
Engineers who mess up their work are given an opportunity to give detailed information about what they did, explain about their mistakes, understand their mistakes, their expectations and assumptions, the effects they had.
While giving this explanation they need not have to fear about punishments. This PSA emails was started in the year 2010 and later in the year 2011, as engineers from Etsy are suffering with complications with the mistakes they made. They shared it all over expectation that this scheme will reduce the barriers of engineers.
Employees are encouraged by other employees to send these self initiated confessions. This technique of understanding about the mistakes is a social contract that benefits author of PSA and the readers.
The mistakes may occur while doing some developments and it will be like error in a code. It is not just a major mistake that cause the site interruption but documenting ‘near misses’ will serve like a vaccine for Etsy. It helps the company to get protected from serious of errors in the future, without anything in the process.
