Following the discussions both elsewhere and on this blog about sprint duration, the questions poses itself – what is the preferred sprint length? So I ran a poll.
And the winner is… 2 weeks.
According to this very scientific survey (1 week on my blog, 228 Visitors, 50 votes), the most popular sprint duration is 2 weeks, followed by (early leader) 3 weeks, which lost by one vote.
The final results are:
|1 week||2 (4%)|
|2 week||18 (36%)|
|3 week||17 (34%)|
|4 week||5 (10%)|
|1 month||5 (10%)|
|longer, but fixed||5 (10%)|
How long should the sprint be? There are many right answers, some of which argued for longer sprints:
But most argued for shorter sprints:
Very short sprints, i.e. 1 week are appropriate for very short projects, say 1 month. To do a 4 week project in 1 sprint, or even 2, does not leave much opportunity for feedback.
Mike Cohn pointed out:
3-week sprints have become very popular over the last 12-18 months. Before then most teams considered them odd 😉 Seriously, it’s a recent change for most teams
And the closing word:
The preferred sprint duration is the one that works best for your team 🙂
I’ll second that!
