  2. WIS Functional Architecture Background • A WIS functional architecture has been developed during 2007 and 2008 to: • Help promote a common understanding of how WIS should function • Support the WIS Specification activity • Provide a structured framework for defining the minimum functional scope of NCs, DCPCs and GISCs (to support the designation process) • The reference point for the functional scope of WIS is the table of “in scope” and “not in scope” items defined at the ICG-WIS in 2007 World Meteorological Organization

  3. WIS Functional Architecture Adopted Standard • The standard known as Integration Definition for Function Modelling [IDEF0] has been adopted for representing the WIS functional architecture • This standard is simple, highly-regarded and results in clear functional representations, which can be interpreted by a broad audience without the need for specialist skills World Meteorological Organization

  4. WIS Functional Architecture Adopted Standard World Meteorological Organization

  5. WIS Functional Architecture Context Diagram World Meteorological Organization

  6. WIS Functional Architecture Level 1 World Meteorological Organization

  7. WIS Functional Architecture Decomposition of A1 World Meteorological Organization

  8. WIS Functional Architecture Decomposition of A11 World Meteorological Organization

  9. WIS Functional Architecture Minimum Component Functionality • Section 3 of the Functional Architecture document includes a table that proposes the minimum constituent functionality for the main logical components of WIS • NC • DCPC (without the functions associated with an RTH on the GTS) • DCPCRTH (including the functions associated with an RTH on the GTS) • GISC • The distinction between DCPCs with/without an RTH function on the GTS has been introduced to facilitate the mapping onto the current GTS architecture World Meteorological Organization

  10. WIS Functional Architecture Feedback and Next Steps • The views of the ICG-WIS on the functional architecture document are most welcome • The next version of the document will • Reflect the feedback received from the ICG-WIS • Include a section that illustrates the pre-existing functions within WIS • Address the open points identified in section 1.4 of the document World Meteorological Organization
