[Smwg] AI2017-0512-54: Create draft Tech Note on State Machines

[Eddy, Wesley M. (GRC-LCN0)[MTI SYSTEMS, INC.]]

Hi Marcin, I like your proposal to fix and simplify the way that the service package status is indicated.

To be clear, we currently have two fields:

-          servicePackageResultStatus (can be TENTATIVELY SCHEDULED, PARTIALLY SCHEDULED, or FULLY SCHEDULED)

-          servicePackageResultType (can be NEW, UPDATE, ALTERNATE, FLEXIBILITY CHANGE)
And both are optional.

If I understand correctly, you think it would be better to consolidate to a single more explicit indication of the service package state, like:

-          servicePackageStatus (can be CREATED, SCHEDULED, ALTERNATIVE, EXECUTING, REJECTED, CANCELLED, ABORTED, ARCHIVED)

This seems basically good to me.  Two questions I have are:

1)      Should the servicePackageStatus be mandatory?  I think so.  I'm not sure why the original book had the equivalent fields as optional.

2)      How are the 3 degrees of being scheduled that the old fields conveyed (tentative, partial, or full) reflected in the state machine?

Dear all,

And here is another debt which I had in terms of an Action Item. Please see attached draft Tech Note on State Machines. Also some small corresponding presentation (content is more or less same).

Uploaded to CWE as well:

I saw Erik had planned some time during Fall Meetings for the State Machine topic, so maybe it would be not bad if you could drop an eye on this stuff (one more doc to be reviewed - add to the list of "Berlin Pointers" ;-). It's not long though... so maybe you can make it...

Best Regards
Marcin
