Here is a scenario we have seen before: you do something great for your PI System users, and when you try to do the same thing at another site that has PI, getting it to work is a nightmare. It may be that they use a different tag naming convention. Or their units of measure are all different. Maybe they did their totalizations different. Or it could be something that takes you forever to figure out, like for example that in their calculations they treat missing data differently than how you treat missing data. For one reason or another, you spend the majority of your time getting their data to look and act the same as your data.
Here's a video that explains why going to an asset centric PI System can solve this problem without having to make changes to the individual sites.
