  • 1. USE Case Working Group
    Update for SMDG SG1 – 13.12.10
    Simon Harrison
  • 2. Update
    Have now had 4 full days of Working Group sessions
    Excellent progress – good cooperation and focus from members
    Producing draft detailed use cases at a level suitable to manufacturers – i.e. down to data description/object level where necessary
    • Meter Reading
    • 3. Meter Settings
    • 4. Prepayment
    All have draft use cases now
    • Upgrade Firmware, Commission Meter, Add Devices all in the firing line for later this week
  • inclusivity
    Adverse weather conditions did not help with attendees in week one
    Only need subject experts for specific use cases
    3rd Party/Non Domestic Member is participating remotely
  • 5. Collaboration tool
    Group is making use of a free, public google site to share documents and to track certain housekeeping items
  • 6. Collaboration tool
    Document repository, with version control and revision history
    Action log
    Record of assumptions
    Meeting log (with papers)
    Supporting papers and guidance
    ERA team doing most of the housework, but others can be added as collaborators
  • 7. SMDG Glossary
    To support the UCWG, we need to have a glossary
    Should use the one Gareth has started, so…
  • 8. Learnings
    Working in a small group is essential – discussions are challenging with 4 or 5 in the room
    Consistency is very beneficial, although adding new people has not been too disruptive to progress
    Offline work will be important to provide drafts, comments against drafts and detail review
    It is possible to produce use cases to a level of detail that is what the manufacturers need to deliver interoperable products
    It should be possible to understand the amount of effort needed to produce a full set of use cases within Q1 2011
  • 9. Next Steps
    Two more ‘wet towel’ days this week – one to do a sweep up and prepare the document
    Definition is close to facilitating interoperability, but may need to go to a lower level to achieve interchangeability
    Present the document to SMDG SG1 next Monday – as a baselined draft, not a final version
    Subject to discussion, this can be provided to SMDG for ratification of the working approach
    Maintain the momentum in the New Year?
    Continue with weekly sessions?
    Provide a plan to clear all 20+ use cases by Mar/Apr/May(?)
