"In my experience, the first step to centralizing the flow of information in a project is by holding regular project meetings. Creating an objective-driven agenda and facilitating the exchange of information during these meetings ensure that everyone is on the same page in tracking our progress. Additionally, keeping everyone accountable by sending action items, or assigning tasks through the project management tool helps with follow-through. If I hear any inaccurate information passed around about the project, I will be sure to address and correct it as soon as I can. That way, wrong information doesn't fester and ultimately cause misaligned expectations. If possible, I would also post regular updates through a knowledge base. If not, regular updates through email or group messaging also help."
