A grid is not a plan
Dates and titles tell production what to make. They do not tell a reviewer why that work deserves to exist.
Give each slot a job
Attach the objective, audience, message role and source campaign to each item. That makes disagreement specific and revision faster.
- Which objective does this support?
- Why this channel and format?
- What evidence constrains it?
Carry the last cycle forward
A new month should begin with accepted decisions and learning, not another blank spreadsheet.
