Looking for some guidance. We are a service provider working with an enterprise client. We have a Jira instance and a project that we have invited our customer to so that they have shared visibility to our agile work. Our customer is heavily involved in UAT verification activities on our project.
Our customer has also engaged another service provider and we are discovering that there is overlap between our work and theirs and we need to work together to deploy changes to shared environments and meet our customer's needs. We need some way of managing both our work streams but also giving our shared client visibility to the work that is underway. Currently we are using spreadsheets to manage the "overlapping" work.
I have been exploring federated Jira environments and am not sure if this is the avenue we should pursue or if there is a better option:

Any guidance or past experience would be greatly appreciated!
