This is the first version of this document and completes the step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was to record as much information on "what we think works" and publish. The effort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of the step 2 effort will then be incorporated into updates of this document and lead to a republished version.
