In addition to that, it has beenrevealed from the past experience that this team can complete 22 story poinls per sprint'According to the lessons learned from previous similar projects, 20Yo story points are added persprint as the uncertainty buffer. Time allocated per sprint is 2 weeks and cost per month has beenestimated as US$ 2,500.e) Estimate the totalclearly

To estimate the total effort required for each item in the priority product backlog, we need to calculate the relative size of each item in story points.

A: Developing User Management Module - 202 story points B: Developing Server Handling Module - 35 story points C: Preparing Release Notes - 154 story points D: Executing Test Cycles - 205 story points E: Integrating Payment Gateway - 10 story points

Next, we need to consider the capacity of the development team. The team consists of 8 members, and based on past experience, they can complete 22 story points per sprint.

Since there is uncertainty in the project, we add a buffer of 20% to the story points per sprint. Therefore, the team can complete 22 + (22 * 0.2) = 26.4 story points per sprint.

The time allocated per sprint is 2 weeks, so we can assume there are 2 sprints in a month.

Now, let's calculate the total effort for each item:

A: 202 story points / 26.4 story points per sprint = 7.65 sprints B: 35 story points / 26.4 story points per sprint = 1.33 sprints C: 154 story points / 26.4 story points per sprint = 5.83 sprints D: 205 story points / 26.4 story points per sprint = 7.77 sprints E: 10 story points / 26.4 story points per sprint = 0.38 sprints

Since we have 2 sprints in a month, we can multiply the number of sprints by 2 to get the estimated time in months:

A: 7.65 sprints * 2 = 15.3 months B: 1.33 sprints * 2 = 2.66 months C: 5.83 sprints * 2 = 11.66 months D: 7.77 sprints * 2 = 15.54 months E: 0.38 sprints * 2 = 0.76 months

Finally, let's calculate the estimated cost:

The cost per month is estimated as US$ 2,500.

A: 15.3 months * US$2,500 = US$ 38,250 B: 2.66 months * US$2,500 = US$ 6,650 C: 11.66 months * US$2,500 = US$ 29,150 D: 15.54 months * US$2,500 = US$ 38,850 E: 0.76 months * US$2,500 = US$ 1,900

Therefore, the estimated total effort and cost for each item are as follows:

A: 202 story points, 15.3 months, US$38,250 B: 35 story points, 2.66 months, US$ 6,650 C: 154 story points, 11.66 months, US$29,150 D: 205 story points, 15.54 months, US$ 38,850 E: 10 story points, 0.76 months, US$ 1,900
