Deploying and refining phase
When you're deploying an automation, it's important to consider how you'll replace the current business process with the new automation, to avoid disrupting the business.
Deploying your automation to production
Add redundant owners
If you have a flow that's used by your entire team, you don't want people calling you up while you're on vacation if it breaks. Make sure you add a couple of co-owners so that they can update the flow in your absence. Who you add depends on how the flow is used. Probably you'll at least want to add your direct manager, who can act as your proxy, and maybe your manager's manager if all their reports are relying on your automation. If your group is large enough, or if you have a lot of team flows, you might consider creating a security group of two or three people who are willing to set aside a small amount of time to keep an eye on all the team flows. Don't add your entire organization as a co-owner, though; that just invites more people to mess up the flow. If your company has a Center of Excellence for Microsoft Power Platform, they might have guidelines for flow ownership.
Keep in mind that the access applies not just to the flows themselves but to the connections they use. For example, if your flow sends mail from a shared mailbox, make sure that the co-owners have access to that mailbox in case they need to re-create the connection.
Use solutions
Solutions are a great way to organize flows to manage versions and migrate from one environment to another. You'll need to start by adding (or asking your admin to add) a Microsoft Dataverse database to your environment. After that's done, you can go to the Solutions tab to create a new solution for your team, or you can create multiple solutions if you have a lot of flows that you'd like to further organize. There are a number of other benefits too, such as native storage for your data, child flows to reuse functionality, and solution export as a backup. Solutions do have some known limitations, though, so this might not apply to all your flows.
Mark it as production
Solutions are the recommended way to organize flows, but sometimes your flow can't go in a solution, or sometimes your solution will get crowded with other drafts and proofs of concept. Either way, we recommend prefixing the names of your production flows with "[PROD]" so that co-owners know to leave it be unless it has issues.
Deploy the automation in stages
To make sure your deployment is successful, you should consider taking the following approach:
Use the automation with a small number of people.
Check that there are no issues for those people.
Have the remaining people start using the automation.
