For any business investment you must to is to build a business case so you can show a positive ROI. Otherwise, money can spend on something else that has a better output.
The same applies if you want to get a better SAP PI/PO testing up and running. And all of my customers of Integration Regression Tool(IRT) must go thru this process. Therefore I thought about helping them out, so you don’t have to start from scratch.
I have created an Excel document with the business case you can find it there.
There are obviously a lot of assumptions that I have made in it. The assumptions are for a medium SAP PI/PO customer based on my experiences. I have tried to explain them in the video that I have made.
In this case, normal usage of testing would cost around 80.000 EUR a year.
If you go for IRT the first year, it will only cost around 40.000 EUR. The second year would be even better because you have made all the initial investment in the testing.
I was trying to see whether you really should be testing. This part had some nasty consequences like have system or factory down for 2 hours or losing a relationship with a customer. Here the price was 85.000 EUR. It had big fluctuations if you depending on how if your system was down every year or every second year.
In January 2019 I published an updated version of this blog. The new blog is called: How to build a business case.
