The calendar has twelve rows, a title in each, and a date. By week three you are two behind, by week six nobody opens the file, and by the end of the quarter somebody makes a new calendar.
It tells you nothing about whether the piece can be written. No source named, no owner, no idea whether the number it needs exists. So the first hard piece stalls, everything behind it slips, and the calendar becomes fiction.
Everybody plans publication and nobody plans what happens afterwards. A review date turns a published page into an asset somebody maintains. A measure agreed up front turns it into something you can learn from.

A published page, a draft, or the topic you are stuck on. An editor reads it and writes back with what to cut, what is missing and what number it needs. No call, no pitch.
