This experience taught me the importance of conducting thorough initial research and risk assessment, especially when dealing with older technologies. Afterward, I started implementing a more rigorous preliminary exploration phase for all projects, where we identify potential integration challenges and allocate additional time in the schedule for unexpected issues. This not only improved our project timelines but also enhanced team communication and preparedness for future projects.”
