2014-06-17 DefCore Capabilities Scoring
|
||||
=========================================
|
||||
|
||||
The DefCore team has put together a scorecard_ combining many criteria
|
||||
to evaluate which capabilities_ of OpenStack should be considered
|
||||
core. They have asked the TC to help fill in the "Aligns with
|
||||
Technical Direction" section, replacing the score in each cell with
|
||||
either ``0`` (for "not needed") or ``1`` (for "required").
|
||||
|
||||
The table below includes the three columns from the "Aligns with
|
||||
Technical Direction" of the original scorecard:
|
||||
|
||||
TC Future Direction
|
||||
|
||||
Does the Technical Committee plan to continue supporting this
|
||||
feature?
|
||||
|
||||
Complete
|
||||
|
||||
Is the feature currently implemented and fully
|
||||
working?
|
||||
|
||||
Stable
|
||||
|
||||
Is the API for the feature stable enough to support over a long
|
||||
period?
|
||||
|
||||
..
|
||||
The table below reproduces the "Aligns with Technical Direction"
|
||||
section of the spreadsheet as it stands on 2014-06-17, based on
|
||||
``defcore.csv``. A follow-up changeset will modify this resolution
|
||||
to reflect the scores of the TC (separate patches will make it
|
||||
easier to discuss the changes from the original values).
|
||||
|
||||
The ``0.5`` values are placeholders for the "undecided" scores the
|
||||
DefCore committee needs us to resolve.
|
||||
|
||||
The other ``1`` and ``0`` scores were decided by the DefCore
|
||||
committee, but as these are technical questions they are also up for
|
||||
review. We should focus on filling in the missing values first, and
|
||||
may want a second pass to update the other values.
|
||||
|
||||
The blank fields are for capabilities that won't be included based
|
||||
on other criteria, so we can score them but don't have to during
|
||||
this pass.
