Hackfests, also known as hackathons or fedex days, are internal events designed to foster team cohesion and encourage the exploration of new technologies and processes by allowing team members to work on any project of their choice for a day. FusionAuth has utilized hackfests for years, highlighting their utility in breaking from routine, enhancing cross-team collaboration, and offering the opportunity for skill development and problem-solving. These events are scheduled in advance and occur during normal working hours, ensuring participation across different roles, including non-technical staff, who can engage in projects like developing mockups, reports, or exploring new sales tools. The key rules are that participants must avoid busywork and are required to present their outcomes to peers and management, which promotes accountability and innovation. Hackfests also provide a platform for cross-disciplinary learning, risk-taking, and understanding between team members, while being adaptable for both in-person and remote settings. Participation is encouraged but not mandatory, respecting individual preferences and circumstances.
