CSSM Colleagues,

Here is my response on the Service Agreement AI.   Please see the attached file.  I will not be surprised if you find a fair degree of similarity with what Wes has provided, but I think you will also see a few differences.

Any volunteers for taking the 3 inputs (DLR/NSN/DSN) and smashing them into some sort of consistent comparative format? :-)  At a minimum I think we can take a look during the WG telecon next week and make an assessment with regard to having enough information to move ahead with some common set of parameters for the service agreement.

Best regards,

For the action on Service Agreement contents, here are generic contents used for some recent NSN service agreement documents.

There are actually 3 different templates, and a Mission Commitment Engineer collaborates with the customer on the services needed, using the appropriate template.
