A development team in your company has been unsuccessful delivering software by its deadline.
You join the team as its new scrum master.
The previous scrum master did not understand the importance of the length of a sprint.
You need to define how long the sprints should be.
Which two factors should you consider to determine sprint length? (Each correct answer presents part of the solution. Choose two.)
A. The iteration length should be long enough to ensure than no more than 20 percent of the total effort is spent performing deployment and administrative tasks.
B. The iteration length should be consistent.
C. The iteration length should be flexible.
D. The sprint length should be long enough to create a usable and potentially releasable product.
E. The iteration length should be longer than one month.
Correct Answer: BD
Explanation/Reference:
B: In the Scrum method of Agile software development, work is confined to a regular, repeatable work cycle, known as a sprint or iteration. Ideally, the length of the Sprint does not change.
D: During each sprint, a team creates a shippable product, no matter how basic that product is.
Not E: Sprints of longer than four weeks (one month) have a smell--the smell of water falling. When a Sprint’s length is longer than a month, the definition of what is being built may change or complexity and risk may increase. By limiting the maximum length of a Sprint, at most one month of development effort would be wasted, rather than several months in a classic waterfall project.
