Roxanne in answer of your questions:
If we deploy and implement this year 2012 with the idea of late year 2012 90 days of data...we can attest at/towards CY end, or even shortly after start of year 2013?. This will satify first year attestation
Yes you can attest 2012 CY anytime after the 90 day period is met, and yes you can attest for 2012 in 2013 probably again as late as Feb 2013.
However second year 2013 we are required to attest for the full year....this supports the premis your intial momentum towards MU can be sustained correct?
Yes you attest to the full year for each subsequent year of MU participation.
Yes you will certainly be able to maintain momentum toward MU once you have the systems in place to achieve success.
Attestation in 2013 then must meet only the $24k threshold or must we also meet a time threshold such as completing a full CY of MU prior to our attestation for 2013 data
You must meet the $24K threshold (if not you will be paid a fraction of the allowed payment) AND you must meet the time threshold.
Here is a little heads up and the reason why you should jump on this asap: we are currently in stage 1 MU. Stages 2 and 3 get more complicated and thus presumably more difficult to simply jump into at a later stage. You are wise to investigate this immediately, unless you have made a business decision not to participate at all. Again, if you are contemplating getting on the MU Incentive program there is no time like the present.
