We recently got asked this question:
The XXX team suggested as a team that we change our 2 week sprints to 3 week sprints as we lose a lot of time spending a whole day on retro, sprint plan 1 & 2 every 10days. If we spread it over 3 weeks we save at least 10% productivity to attend to Business As Usual (BAU) stuff and sprint stories. This should not impact velocity & focus on the sprint. What is your take on this?
As this is a common question, we decided to blog our answer – hopefully it can help others who are also wondering about this.
Longer sprints are in our experience never the solution. If it takes you a day to plan for 2 weeks, it will most likely take longer for 3 weeks. Remember sprint planning 1 and 2 are supposed to be 1 hour PER week of the sprint so for a 3 weeks sprint that is 3 hours of SP1 and 3 hours of SP2, which probably means it’s going to run longer than 1 day with the review and retro. I suggest rather finding ways to make your planning and grooming meetings more productive and focused.
