Workable
Defined at either engineer or increment level. Options - explicit/none - endeavor must specify increment, validation of end or overlap, start, end, duration (shall fit into the increment for the entire duration). Explicit assignment overrides matching - can be used for endeavors spanning several increments and perhaps not matching any. E.g. a long running feature spanning two or more years.
