Deadlines: work backwards from the event date

~7 min

Reading

Set deadlines at the start of a project for each phase. Work backwards from the event date. Surprise deadlines are usually a sign nobody worked backwards.

Working backwards from the event date is the single most useful PM habit a community organizer can build. Start at the end: the action, the gala, the briefing, the launch. Put it on the calendar. Now ask: what has to be true the day before? The week before? Two weeks before? Each answer is a deadline.

Common phases for community work: Recruitment Period, Surveying Period, The Event, A Debrief, Follow Up. Each phase has its own internal deadlines — recruitment has a "list finalized" deadline before it has a "first ask sent" deadline; the event has a "venue confirmed" deadline well before "day of".

A workable timeline lives in a single shared place. A spreadsheet, a Google Calendar, an Asana board — pick one, and only one. Two timelines means the team will look at the wrong one. If different stakeholders need different views, generate them from the same source.

Build a buffer week into every phase. Things take longer than you think. The PM's job is not to bend reality to the original timeline; it is to surface slippage early so the team can decide what to drop or push. A timeline with no buffer is not a plan; it is a hope.

Buffers are not slack; they are where you absorb the thing you didn't see coming.

Marco re-recruited two from the standby list and redistributed the Vietnamese shift before the dry run. BUFFER B week of 4 / 11 VN translation review surfaced two phrases that read condescending. Linh rewrote them, the script went back to Janelle for re-approval on schedule. Both buffers got used. If neither had, the next plan would have padded with fewer. Buffers are calibrated by what they catch.

Learner action

On paper, put your project's end date on the right. Working leftward, write each phase and the deadlines inside it. Add a one-week buffer to each phase. Now transfer it to a single shared calendar.
