Development timeline

Aha! Develop extension that explores techniques for evaluating feature estimates to forecast development timelines.

It provides these contributions:

• Timeline: A view contribution showing the projected range of how long it will take to complete a feature based on its estimate, estimation uncertainty, and team velocity.
• Estimation uncertainty: An account setting to measure how much inaccuracy to allow for during estimation. Represented as a percentage from 0-100%. Higher uncertainty means estimates are less reliable.
• Default estimate: An account setting to specify the default estimate for any unestimated records.
• Default velocity: An account setting to specify the development velocity for any records not assigned to a team.
• Total assignees: An account setting to specify the total number of developers that will work on a release.

Demo

Current limitations

• Requires estimation in points.
• Uncertainty defaults to 25%. Meaning for a task estimated at one day, we'd expect to see it completed within 0.75d – 1.25d. I've set this based on previous experience, but we can tune it via an extension setting.
• "Time in progress" means exactly that: total time spent in an "in progress" status. Moving it out of that status category "stops the clock."
• It'll probably break a lot. Open an issue in this repo and I'll fix it.

What's next

• Projected durations based on individual velocity
• Exclude non-business-days from time in progress
• Support epics and requirements
• Project dates for collections of records (releases, epics, features)
  • Releases
  • Epics
  • Features
• Compare original vs remaining estimate projections ("trending late", "trending early")
• Explore "Sprint inflation" and "Adjusted minimum capacity" concepts
• Support time-based estimation
• Factor unestimated work into timeline
• Use initial estimate if no best estimate (with a larger uncertainty)

Installing the extension

Note: In order to install an extension into your Aha! Develop account, you must be an account administrator.

Install the Estimate analysis extension by clicking here.

Working on the extension

Install aha-cli:

npm install -g aha-cli

Clone the repo:

git clone https://github.com/trydionel/estimation-analysis.git

Note: In order to install an extension into your Aha! Develop account, you must be an account administrator.

Install the extension into Aha! and set up a watcher:

aha extension:install
aha extension:watch

Now, any change you make inside your working copy will automatically take effect in your Aha! account.

Building

When you have finished working on your extension, package it into a .gz file so that others can install it:

aha extension:build

After building, you can upload the .gz file to a publicly accessible URL, such as a GitHub release, so that others can install it using that URL.
