The Entry Criteria is incorrect. The spec for Activity Space Operate the System reads: "Entry Criteria: Software System::Ready".

I believe this should read "Entry Criteria: Software System::Operational".

My reasoning is as follows: The previous Activity Space "Deploy the System" reads "Entry Criteria: Software System::Ready, Completion Criteria: Software System::Operational". The Entry Criteria should match the Completion Criteria for the previous Activity Space. It also makes senses to not have both Activity Spaces active at the same time.

Updated and added definitions of detail cards proposed. The detail cards represents a very important aspect of Essence to support agile approaches and in particular game playing.

See attachment for proposed updates (original link: https://www.dropbox.com/s/i69o6rr1lh3x1y3/Essence_detail_card_syntax_update_2.docx?dl=0 ).

Update the definition of detail cards

The proposed updates are agreed to.

The term "checkpoint" is loaded and used within the software industry to denote high-level checkpoints that is passed between lifecycle milestones and the like.

Suggest to rename checkpoint to "check" instead.

Retain the term "Checkpoint"

The term "checkpoint" seems colloquially and technically a better English term for items on a checklist than "check". Further, this would be a backward-incompatible change to the metamodel that would effect more than might be expected, because of the importance of checklists in Essence. Therefore, it changing the term is not considered important enough to warrent the effort of the change.
