DHINESHKUMAR NAGARAJAN Setting up a PMO is a great move! I’d suggest starting with a few key documents like project charters, schedules, and risk logs. Keep your processes simple initially and focus on aligning them with organizational goals. Develop a step-by-step process for project initiation, planning, execution, and closure. Use tools like project management software for visibility.
Since you're the only PMP-certified person, your role is key to educating your team on the importance of these processes. As you get buy-in, gradually expand the scope of the PMO.
