Metrics & manageability are considered in D-AC0018 [1].
Hao He championed it, and we are refining it in Reliability Task Force
Can we  refine D-AC0018 to include this proposal?

Subject: New top goal proposal: Management and SLA

I was reading our requirements document and realized that there is not a
proper attention being paid to a very important aspect of a service:
agreements between a user and the owner. This is not any less important
element than security for that sake. How can business components comprise a
"digital economy" without agreements?

Now, agreements have to be established, maintained, accounted for, and may
be enforced. Management metrics/instrumentation is merely "how" details of a
bigger goal, and the Reliability is an intermediate effect/characteristic.

Reliability goal has other aspects in messaging, etc. and while I do not
want to contend with it in any way, I'd like to pull Manageability and SLAs
higher on the stack. Here is my proposal for the new top goal.

Goal: Manageability and Service Agreements 
Web Services Architecture must provide a manageable environment for
establishing, maintaining and enforcing Service Level Agreements.

Critical success factors for this goal are: 
To develop standard reference architecture for Web Services that: 

1. Identifies how to express SLAs and associate them with Web services 
1.1 Service usage policies 
1.2 Web service licensing standards 
1.3 Identify technical/legal boundary 

2. Identifies automatic/manual SLA negotiation process 

3. Identifies how agreements are established and preserved 
3.1 License persistence and verification procedures 
3.2 Privacy of SLAs 
3.3 Integrity and non-repudiation of SLAs 

4. Identifies management/instrumentation/metrics standards/technologies
necessary to meter and account for service usage

4.1 - subsume/reference D-AC018 

5. Identifies procedures/standards necessary to maintain the agreement 
5.1. Identify technology/commerce boundary 

6. Identifies SLA enforcement procedures 
6.1 Usage/metrics reconciliation procedures 
6.2 Attempt/provide for automatic conflict resolution 
6.3 Identify technology/legal boundary
