3. Requirements Process: Common Complaints
Present development process yields a patchwork of multiple, overlapping, and potentially inconsistent products
Products are introduced without consideration of regulatory impact
Providers define WHAT products are required and HOW they will look and then ask users to approve after it is too late to make changes

5. User Input Summary
Numerous groups have input to requirements, overall investment is substantial
Same representatives serve on many groups, individual commitment is substantial
Some groups provide needed oversight on a broad range of issues
Other groups provide technical expertise on design of specific products
Both types of involvement are needed and can’t be done by same group

Optional Path

7. Contents of UNA & ConUse
Identify users (decision makers)
Document operational decisions requiring weather information
Describe ideal information needed to support operational decisions
Specify performance metrics (how good is good enough?)
Identify needed Rule/guidance changes
Describe needed user training
Define needed access architecture (ConUse only)
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

8. Approaches to Solution
Systemic: Develop a roadmap to address to show plan to reduce product proliferation and manage unintended regulatory impact
Product Specific: Obtain more effective input from user experts on individual product design
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

9. Roadmap
Shows migration path from existing products to new product suite:
Identifies product mergers and replacements
Done for each weather category and user class
Identifies regulatory impacts & develop plan for rule/guidance change, domestic & international
Identifies priorities for supporting research
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

10. Roadmap Production FAA/NWS draft Roadmap based on:
Mission Needs Statements
Current UNA & ConUse documents
Current research plans
AWTT Users Group review and comment
Iterate as needed
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

11. Enhance Input from Expert User Teams for Product Design
Document/validate results from ongoing expert user teams
Document early in ConUse & update frequently
Publish ConUse early & employ systematic review
Enhance expert user teams
Employ Users Needs Analyses before R&D
Selectively add user teams during R&D & document results in ConUse for systematic review
Enhance AWTT User Meetings for oversight
Systematic web review of UNA/ConUse documents
Double meeting frequency to quarterly?
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

12. Constraints
User input processes must adhere to Federal Advisory Committee Act and Administrative Procedures Act
Increased PBO emphasis on measured performance improvement
Reduction in accidents
Increased capacity & efficiency
Limited time & travel resources for requirements processes, both sides
S:\1ARS100\Admin\OrgMgtProcess\AWTT\FPAW03\3AWTTupdateFPAW03v1.0.ppt

13. Summary To improve requirements, FAA will develop, with user input:
A roadmap showing migration to fewer but better product suites with fewer unintended regulatory constraints
Improved users technical input to product design.
Both managed thru enhanced AWTT users meetings
