I have been obsessed with finding better ways to make integrations better on. I have been looking at different ways to make the integration better on. It has not been easy and I have created multiple models to capture the most important part of it.
There is a lot of project models out there that help in all phases of a project. They do not take integration specific questions into account. For obvious reasons. It is still something that should be addressed by the people making the plans and developing any integrations.
It is an iterative process because you will need to learn what works and what should be changed. It will mostly be the places where your pattern is different than what you have created earlier. It is a good idea in the design phase the identify the pattern that is used for the integration.
In this iteration, i made it a bit more generic. To support the change in processing that allows users to consider other platforms that just SAP PI/PO. This is an important part of the development because you now have many options to deliver the same integration. Or there could be tools that are better suited to that specific integration.
