hope someone could clarify the correct maximum duration for a sprint retrospective!

from scrum guide 2013: "this is a three-hour time-boxed meeting for one month sprint. for shorter sprints, the event is usually shorter p12, 1st paragraph
from Software in 30 days:"This meeting should never exceed four hours" p60 - "conduct the sprint retrospectives"
sub chapter

should someone consider as the scrum guide and scrum open relative answers as correct?

Hi Nikos,

As the exam is set by scrum.org the question will be based on scrum guide contents.
If you look at Appendix 1 page 131 of the same book Software in 30 days.
Time is defined the same as scrum guide, so its a kind of contradiction of terms.
Understand your point you are putting forward RE timeboxes as it could be confusing.
As a SM you would be keeping the events to timeboxes, as far as this is concerned
I would go with the timebox that the scrum guide recommends and also page 131 of that book.
Could also be worth dropping Ken or Jeff a mail in the thinking behind the four hour time listed.
Share the result with the wider community in this post.

Mehdi spotted this back in January. At the time, I suggested it was a typo and no-one has contradicted me on that. See:


Taken very literally of course, the book is also right. The claim that a Sprint Retrospective should never exceed 4 hours is a valid one.

Hi Nick,
Normally you should have an 1 hour Retro, for a one week sprint, ergo 2 hr for 2 weeks etc.
