The last strategy focuses on a model that includes two different groups who need to work together to adapt the infrastructure to the Agile method being used. The first group is the project team who is using Agile to deliver working software for the end-user (the ultimate customer who perceives the business value). The second group is the infrastructure team who improves the infrastructure. Interestingly, the project team becomes the customer for the infrastructure team, just as the end-users are the customers for the project team. Just like the standard practice where the customer should be part of the project team for continuous feedback, the same holds true that a member of the project team should be on the infrastructure team. This is important to understand because the project team is the group that must assess the value of the changes so that the infrastructure team knows which changes are perceived to be of most value and which to work on. The customer stream in Diagram #1 illustrates these relationships.
