Google Pay has given the Project Managers the following details for expansion:

1. Google wants to expand their support for public transport and wants to allow users to save the tickets to concerts, shows, and events in Google Pay.

2. They want to work closely with their partner banks across the globe to bring innovation to this industry. They will allow newly created credit cards to be added to Google Pay instantly without waiting for the physical cards to arrive via post.

3. Google Pay wants to offer a number of new features that are designed to streamline and personalize many financial management activities for its users. Users who will connect their bank accounts or credit cards to Google Pay will receive regular spending summaries and see their own spending trends and insights over a period of time. Google Pay will understand this spending pattern and automatically organize the users' expenditure. This will allow the users to search across their transactions using Google's functionality with simple terms like "food" or "last month" or "Chinese restaurants" to find the relevant transactions done by the user.

4. Google pay wants its user interface to be built around human conversations. For example, if a google user needs to split dinner, their rent, or any other expenses with more than one person, they can create a group on the app. The app will split the bill, and also keep a track of who's paid and adjust the balances in a single place.

5. Google pay wants to introduce security measures like alerts whenever a user might be paying money to a stranger. It will have customizable privacy settings and will never sell the users' data and transaction history with third parties and or with other Google products for targeted ads.

6. Google Pay wants its users to use the app to open something known as a Plex bank account. This would be launched in the U.S. market first, and if it is a success, they plan to roll it out to other countries as well.

Plex is a new mobile-first bank account integrated into Google Pay. Plex accounts will be offered by various banks and credit unions. They will have checking and savings accounts and there will not be any monthly fees, overdraft charges, or any minimum balance requirements. This would be launched in the next 6-8 months. Google Pay wants to tie up with various U.S. banks and credit unions like Standard Federal Credit Union (SFCU), Citi, Stanford, and Green Dot to start offering Plex accounts in Google Pay.

Can we set up a PMO for the above project? Kindly clarify the roles and responsibilities of the PMO and documents needed by the PMO from all scrum teams.
