Daily Scrum no longer a timeboxed event? Why?

It's still timeboxed, even though the word isn't explicitly used in the definition. Timeboxing is the allocation of a maximum time to an activity. Since the Daily Scrum has a maximum time of 15 minutes, it is timeboxed.

Hi Steve,

I had wondered about this when the 2020 guide version came out. Wording changed from "The Daily Scrum is a 15-minute time-boxed event" to "The Daily Scrum is a 15-minute event". Why remove "time-box" from Daily Scrum description?

One distinction with the Daily Scrum, and perhaps why it was simplified to remove "time-box" reference, is that it is the one event that does not change based on Sprint duration. If you have a 3-day Sprint, or a 1-month Sprint, the Daily Scrum is still a 15-minute event. All other events follow the "<Scrum event> is timeboxed to a maximum of <n> hours for a one-month Sprint. For shorter Sprints, the event is usually shorter."

As Thomas states, the Daily Scrum is still time-boxed as defined with "15-minute event". Like other events that is the longest it should take, and it can end early if its purpose has been satisfied.

This sentence in the Scrum Guide under the Scrum Master section tells me that the Daily is still timeboxed as it mentions all Scrum events ate timeboxed:

• Ensuring that all Scrum events take place and are positive, productive, and kept within the timebox.

I recall at the time of the 2020 changes @EricNaiburg asked Ken Schwaber about this, and Ken confirmed the intent of the Daily timebox has not changed regarding this.

It's vigorous pruning to remove fluff. Referring to "a 15-minute time-boxed event" is arguably unnecessary verbiage, in so far as "15 minutes" not only confirms the time-box but stipulates what it is.
