Currently no but with the idea that most of the services are following the managed service approach, the templates of SLA need to be more flexible and practical due to the different understandings we have on SLAs and the nature of the business requirements from one department to another.
I feel like the service providers deliberately obfuscate the inner agreements to make it incredibly difficult to discern just what the terms of the agreements are. It is almost like the old cell phone bills of the late 90s, where it was so complicated, you didn't read on to understand the contract and agreement.
unfortunately it is not as clear as it should be one of the reason got to be the lack of confidence both parties have in their ability to delivery as per the committed terms. Current service capability measures are not as accurate which make the basis of such agreements very vague and difficult to agree on.
