Incident.io maintains quality at pace by using "Polish Parties," meetings held towards the end of a project where feedback is gathered from people who were not involved in building it. These sessions involve employees from various departments, including engineering and product managers, designers, and stakeholders. The purpose of Polish Parties is to gain fresh perspectives on the product and identify minor flaws or user experience hiccups that may have been overlooked by those deeply involved in its development. By involving more people, both within and sometimes outside the team, valuable insights into how to improve the product are obtained. The success of these meetings relies heavily on trust and a blameless culture where feedback is constructive rather than harmful or combative.
