Ok, I'll split the question into 3 and make it clear that you didn't answer it.
What is the utility that IOTA provides?
There's nothing in your link that talks about the utility that IOTA provides. There's machine to machine payments, but that's not really utility because currently machines don't pay each other, users do. There's no actual demand for machines to pay each other. This isn't unsurprising because it's a new technology and sometimes technology has to develop the demand.
What are Bosch are deploying at production?
The link you supplied has nothing being deployed at production. There's talk of the XDK, but that's a developer kit, not a final product. If you go to the XDK site and search for IOTA, iota or tangle you get no results. This is not contingent with the importance that IOTA supporters place on the Bosch relationship.
Where is this used?
According to the link you've posted, there are a number of Proof of Concepts, but no actual deployments at production scale. It's not being used outside of PoC at this stage.
The thing is, you could've just tried answering the question but posting an AMA that doesn't answer it is frankly, shitty. If you believe it does answer the above 3 questions, at least do the decent thread and link to the comments with the answers.
What is the utility that IOTA provides, that Bosch are deploying at production, and where is this used?
You won't get a decent answer because as far as I can tell there isn't one.
