You are the Scrum Master and your Development Team of 6 members has completed six Sprints with the following information:
Sprint 1: 10 pontos -
Sprint 2: 11 pontos -
Sprint 3: 15 pontos -
Sprint 4: 14 pontos -
Sprint 5: 15 pontos -
Sprint 6: 10 pontos -
The remaining story points for product development total 42. What is the approximate number of Sprint required to complete product development?
To determine the number of Sprints required to complete product development, we first calculate the average velocity of the team. The total story points completed in six Sprints is 75 (10 + 11 + 15 + 14 + 15 + 10), and the average velocity is 75/6 = 12.5 points per Sprint. To find out how many Sprints are needed to complete the remaining 42 story points, we divide the total remaining story points by the average velocity: 42 / 12.5 ≈ 3.36. Since we can't have a fraction of a Sprint, we round up to the nearest whole number, which gives us approximately 4 Sprints.
Should be B: i.e., 5 because - minimum that can be done in a sprint is 10. Hence for 42, atleast 5 sprints needed (assuming least per sprint is 10)
how did u derive minimum that can be done in a sprint is 10? v shud be taking of past delivered sprints. so its 75/6=12.5
B; This will be based on the worst case scenario. That is, the least pontos. so 42/10=4.2 and to nearest whole number = 5.
considering the velocity of team based on past sprints it should be 4 only
correct answer is c i.e 4 sprints
Could you please explain this? i'm stuck on it. Thanks
Average work done in 6 sprints - 70/6 = 11.6 rounding off to 12. remaining backlog - 42. # of sprints required 42/12 = 3.5 rounded to 4
The total completed story points from the first six sprints is: 10 + 11 + 15 + 14 + 15 + 10 = 75. The remaining story points are: 42. Adding the completed and remaining story points: 75 + 42 = 117. Now, to calculate the average story points per Sprint: 117 (total story points) / 6 (number of completed sprints) = 19.5. So, each Sprint, on average, has covered 19.5 story points. To determine the approximate number of Sprints required to complete the remaining 42 story points: 42 (remaining story points) / 19.5 (average story points per Sprint) ≈ 2.15. Since you can't have a fraction of a Sprint, rounding up gives you approximately 3 Sprints. So, the correct answer is: D. 3
The correct answer is C (4 Sprints): 75/6=12.5 ; 42/12.5= 3.36 should be rounded to 4
C is correct answer
Answer is B
as we are mentioning something which is by definition unpredictable, best approach is to use montecarlo simulation. Average or last sprint is not giving any good prediction. So can be several answers
