Scrum for Trello

Scrum for Trello adds functionality to the awesome trello.com for use in Scrum projects.

Trello is the perfect online equivalent of the whiteboard with sticky notes aka the Scrum board. One element we use are the storypoints. TrelloScrum gives you the ability to make use of story points in Trello.

Setup

Scrum for Trello is a Chrome extension. There is a version of it on the webstore, but it is currently broken due to changes Trello has made to their website. This repository is a fork of the original repository, with a (hopefully) fixed version.

Because of that, you can not install it via the webstore. You can only install it as an unpacked extension by cloning this repository and installing it from the Chrome "Extensions" page.

These changes are provided AS IS. I am making this fix for my own benefit, and I will try to keep it working as long as that is feasible.

If you don't know how to clone and install, this is the simplest method:

  1. Click on the "Code" button/dropdown on the page for this repo
  2. Choose "Download ZIP" and save the zip file to your machine
  3. Extract the zip file on your machine
  4. Open Chrome and go to Extensions page (you can either find and click on the "Manage Extensions" option in the menus or put chrome://extensions/ in your address bar and load that page directly)
  5. If it isn't already, turn "Developer Mode" on
  6. On the "Extensions" page, click the "Load unpacked" button
  7. Find the TrelloScrum-master directory that you extracted from the ZIP file and choose it. Note: the zip program may have created an outer TrelloScrum-master directory; if it fails to load, try going into TrelloScrum-master and see if there is another TrelloScrum-master directory inside it. The directory you will want to select will have an images directory in it.

How does it work?

In the card titles you can add the storypoints between parentheses. The assigned points will be picked up by TrelloScrum and displayed in the upper right corner of the card.

For each list the total amount of story points will be calculated and shown in the title of the list.

Every second the story points will be detected and calculated. So changing a number or moving a card will be reflected almost immediately.

Credits

TrelloScrum was developed by Marcel Duin and Jasper Kaizer during our pet projects time at Q42.

Great improvements made by @nicpottier and @paullofte:

  • The point value is moved to be a badge on the card.
  • Added support for Zero Point Cards (0), Unknown Point Cards (?), Decimal Value Cards (.5)
  • In addition I added the functionality to have the list total reflect the current filtered set of cards.
