Building the milestone calendar
A milestone calendar is a list of dates, a named owner who maintains it, and a rule for what each date produces. The rule matters more than the list, because the list will be argued over and the rule will be applied. A workable calendar is short — four to six entries for the first five years, plus an exit entry — and each entry states who qualifies, what is given and who authorises it. Where the calendar is longer than that, the additional entries almost always exist because one team wanted them rather than because the organisation decided them, and their presence is the mechanism by which two standards become normal.
