Using Slack for Shape Up
De facto standard for workplace communication — most PMs will use Slack daily, and it appears constantly in job descriptions. When combined with Shape Up, this makes Slack a strong candidate for teams who want a structured, repeatable workflow without sacrificing flexibility. Shape Up works best in Slack when you leverage its custom workflows to implement the framework's key practices directly in the tool your team already lives in.
Shape Up (Basecamp's methodology) works in 6-week cycles with fully shaped pitches — no backlogs, no sprints, no estimates. Teams get the full cycle to solve a problem however they see fit.
How to set up Shape Up in Slack
Set up your shaping workspace
Create a dedicated "Shaping" space in Slack separate from delivery. Configure a custom workflow: Raw Idea → Being Shaped → Ready for Betting → Accepted → Cycle. Only PMs and shapers have write access to this space during the shaping phase.
Create pitch documents within the tool
Create a naming convention for pitch cards in Slack: "[Pitch] <Name> — Appetite: 6w/2w/1w". Include the pitch content in the card description or linked document. Keep all pitches in one list for the betting table.
Configure 6-week cycle projects
For each cycle, create a project in Slack with a hard end date 6 weeks away. Use a list view for tasks. Teams generate their own tasks from the pitch; the PM does not create the task list. No backlog, no sprint planning — only the pitch scope.
Manage the hill chart (progress) and cooldown
Use Slack's progress tracking to give a weekly "hill chart" update: which tasks are still unknown (uphill) vs being executed (downhill). At week 6, the cycle ends. Configure a "Cooldown" project template where teams file bugs, explore ideas, and clean up technical debt during the 2-week break.
