1% canary

This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

Fast feedback is one of our core values for building software. For many years, we've used the canary release approach to encourage early feedback on new software versions, while reducing the risk through incremental rollout to selected users. One of the questions regarding this technique is how to segment users. Canary releases to a very small segment (say 1%) of users can be a catalyst for change. While starting with a very small segment of users enables teams to get comfortable with the technique, capturing fast user feedback enables diverse teams to observe the impact of new releases and learn and adjust course as necessary—a priceless change in engineering culture. We call this, the mighty 1% canary.
