The Process Architecture is the hierarchal design of the processes. As the business undergoes changes and processes become more complex, a strong process architecture ensures that processes remain in their optimal state. Organizational strategy, structure, process ownership, and program portfolio are some of the key considerations that go into defining the architecture.

In Stages, since each of the processes resides in its own workspace, process architecture is represented by the hierarchy of the workspaces. Before integrating it into the next process in the hierarchy, it is recommended that each process should be baselined (versioned) and only the valid version of the process should be integrated.

Above is an example of process architecture. Global elements like phases & milestones, common roles (e.g. stakeholders) are defined at the corporate level, they have been defined in a workspace called ‘Lifecycle Management’. The other process areas contain discipline specific processes within them which interface with 'Lifecycle Management' process elements.

Furthermore, all the process areas are integrated into a single Standard Process workspace called ‘Software Engineering’ which contains all their process elements (workflows, activities, roles, phases & milestones, work products, and guidance).

In the final layer, specific programs have been instantiated from the ‘Software Engineering’ workspace. This is done by first integrating the ‘Software Engineering’ process into the Program workspaces and later tailoring each of the Programs.

Below we see how the Process Areas defined in the above example would show as workspaces in Stages.

In order to integrate a process into the next level, use the option Add module on the Process start page. In our example, once the Software Engineering workspace is created, all the process areas are added at one go by using the Add module option. The recommended practice is to select the valid version of the processes to be added.

For any existing workspace, more modules can be added by navigating to Management>Process Modules and clicking or tapping on Add Module.

Once a valid version of a process module has been released, the processes where it is integrated needs to be manually updated to consume the valid version.

Navigate to Management > Process Modules of the integrated workspace and select Update. Once the valid version is updated, the circular orange icon changes to green with a ‘V’ in it.

Multiple modules can be updated within one action by using the … menu in the top right and then selecting Update.

A module can also be removed from an integrated process by selecting the Remove operation. This will remove the inherited process elements of the selected module from the integrated process workspace.
