What should I do when setting up a new PMO or making changes to an existing PMO?

When we establish a new PMO or change the existing PMO practices, we can follow an assessment process described as follows: 

• Workflow optimization typically takes six weeks, starting from understanding each process's business processes and workflows. For each process, we need to know what the business uses, the steps, who are involved in each step, and the relationship between the steps.
• New process setup typically takes 8~12 months to implement if there is limited executive engagement. The process setup requires stakeholders to review and propose the new process for buy-ins short proof of concept project to test the new approach and collect feedback. Then, we followed the implementation of the process with details guidelines and support. 
• Project flow restructuring: After we set up the business process, the project management needs a deep dive that takes 12 months, which is the destructing based on industry best practices, which typically fall into Agile, Waterfall, or something missing both. 
• People change: this is a challenging part that usually takes 12 months. We must understand each team member's and stakeholders' perspective, expectations, and working style. The goal is to make sure their voice gets heard, engage their participation, and accommodate their needs for long-term support. 

1. New sdtarndard adoption. Typically takes 12 months to gain momentum. The process requires early engagement for input, creating standards, and review with the team, starting with initial adoption and collecting feedback. The bar should be introduced in steps to avoid dramatic changes in the process and sudden void increases in the overheads. 

These are the PMO setup and change management that we have experienced. We hope this is helpful to you. ​
