One key lesson I've learned as a CIO is the importance of communication between IT and other departments. In the past, I assumed tech teams understood the business's needs without much explanation. However, after a project fell behind due to unclear expectations, I realized how crucial it is to keep open, clear communication. This lesson shaped my approach to working closely with all teams, ensuring alignment and understanding. By fostering better communication, we've seen project success rates increase by 25% at PinProsPlus.
