This is a very tentative proposed process, based on an attempt to sum up discussion at the [[AW Groupies| AWgroupies]] informal meeting on [[AWGroupies_oct16|October 16]]. Please note that this is deeply a open, collaborative, collegial process, see [[IEEE 1471]] for some perspective on the overall approach we are trying to pursue.

'''Please comment on this, a shared, consensual view on this is really important!'''

The overall flow of the effort is roughly:
in parallel:
* Enumerate use cases
* Coalesce into [[Viewpoint Advocacy Groups]]
* Lay out common formats for various work products such as use cases
* Examine and, informed by code and analysis, validate the architectural assumptions and overall approach proposed in [[Proposed Architecture|High Level Architecture proposed by Linden Lab]]
* Enumerate and describe all the current services within SL
* Enumerate key crosscutting concerns such as performance, security, scalability, possibly via a VAG, or as a side effect of one or more VAGs

Once we have coalesced, the VAGs will, in parallel work through the following steps
* Work to get a set of use cases, in a common agreed format, with enough detail to drive design discussions
* Propose basic approaches in enough detail to drive the next major steps
* Surface concerns to other VAGs and the overall community
* Code sample implementations of illustrative designs

Ideally, at this point, we will have:
* A validated set of architectural assumptions
* A large set of proposed solutions, tied to use cases by the VAGs
* A core group of people advocating the various viewpoints
* An enumeration of the current SL services
* A set of key crosscutting concerns to be used when looking at our work
* Working code samples to help validate designs and raise concerns

From this, we will need to forge a broad consensus on the overall approach, informed by the work in the first step. The broad consensus would permit us to move into a more detailed round of design, again
driven by VAGs.

* Define the full set of formal entities in the architecture
* Define the full set of services, protocols, workflows and any other implementable components in the architecture
* Produce sample implementations of key services and components (Broader, larger efforts than in the first phase)

At this point.. in theory.. we have the simple task of
* Define each service in sufficient detail to allow an implementation to be built
* Define each protocol in sufficient detail to allow messages to be constructed and parsed
* Define each interaction pattern in sufficient detail to allow complete interactions to be tested
* Define any profiles/subsets in sufficient detail to permit the profiles to be implemented
* Describe any other materials we identify which would be necessary to allow the creation of conorming components, and

oh yes and "Code it all and test it"
