PROJECT MANAGEMENT

Reschedule downstream Asana tasks when an upstream milestone slips

Watches an Asana milestone for due-date changes and, when it slips, shifts every dependent downstream task by the same number of days and posts a summary to the project's Slack…

How it runs

The automated pipeline, trigger to output.

  • TriggerAsana milestone due-date changedAsanaAsana
  • LogicCompute slip in days; skip if not later
  • ActionFetch all dependent downstream tasksAsanaAsana
  • ActionShift each dependent task's dates by the offsetAsanaAsana
  • OutputPost reschedule summary to SlackSlack

What it does

When the due date of a flagged milestone in Asana moves later, this workflow recalculates the slip in calendar days and pushes that same offset onto every task that lists the milestone as a dependency, then announces what changed.

When to use it

Run this on any project where a single milestone gates a chain of follow-on work (design sign-off, API freeze, vendor delivery) and you are tired of dragging dozens of dependent tasks by hand every time a date moves.

How it works

  1. 1Asana fires a webhook when the milestone task's due date field changes.
  2. 2A logic step computes the delta in days and exits early if the date moved earlier or stayed the same.
  3. 3The workflow queries Asana for all tasks whose dependencies include the milestone.
  4. 4For each dependent task it shifts the start and due dates by the computed offset, respecting existing gaps.
  5. 5A Slack message lists the milestone, the slip size, and each rescheduled task with its new date.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect AsanaTasks, projects, milestones — everywhere.
  2. 2
    Connect SlackChannels, DMs, threads, mentions.
  3. 3
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
