No, not talking about Iran. Talking about this article in Managing Automation where ERP vendors basically take the position of “Not sure about SAP, but we sure deliver value from maintenance”.
The only way to say if you are delivering value is to let your customers vote. As I wrote here - “Let it float”. Your customers may go to third party options, or may ask you for a low-touch maintenance plan at 5% a year or may tell you you need KPIs or tell you they are happy cutting you annual checks at current prices.
Let your customers speak. And let unbiased observers certify the results of the poll.
Otherwise expect rioting in the streets, even as you repeat on official TV that you won and are delivering value.
