How good does a painter apply colors on a canvas? Can a poet make rhymes twice faster? Does software engineer produces efficient code?

These questions are all about similar problem - how to evaluate a performance of an artistic person? Unfortunately there is no single answer nor universal solution yet. At Booking.com we set up our own processes which apply to 1500+ IT employees. We evaluate performance based on not only what people did, but also how did they do it, using all available data from peers around.

From this talk you will learn what to take into account while evaluating developers performance, how to keep the process efficient and how to make sure you are fair and not offending anyone.
