Please work through each problem and help me understand all steps
All questions 1,2,3 and 4.
Background
All the questions in this homework are related to work at 2Technology, Inc. You are the project manager for the first (v1.0) release of 2's latest product, ChordArc.
The software team that will be working on this product is the "Avengers" development team. The Avengers operate using the Scrum model with 2-week sprints. Each sprint includes 10 working days; sprints start on a Monday and finish on the Friday of the second week.
The questions in this assignment are sequential and happen at specific dates.
Instructions
Question 1: Product Release Estimation (December 1, 2023)
Before starting coding on the project, the product manager worked with all their stakeholders to show a product backlog of the required user stories for v1.0 of ChordArc. This included meeting with the lead engineer on the team to come up with t-shirt size estimates for all of the user stories.
Product Estimates:
Rank | User Story | T-Shirt Size |
---|---|---|
1 | US1 | M |
2 | US2 | M |
3 | US3 | L |
4 | US4 | S |
5 | US5 | XXL |
6 | US6 | M |
7 | US7 | M |
8 | US8 | M |
9 | US9 | S |
10 | US10 | L |
11 | US11 | M |
12 | US12 | M |
13 | US13 | XXL |
14 | US14 | L |
15 | US15 | L |
16 | US16 | L |
17 | Accessibility Plan | S |
18 | Prefs Dialog | M |
19 | DB Table | M |
20 | Tutorial | M |
21 | Payment Pipeline | XL |
22 | Installer | M |
23 | US23 | XS |
24 | US24 | S |
25 | US25 | XXL |
26 | US26 | XL |
27 | US27 | M |
The t-shirt sizes were based on the following timetable:
T Shirt Sizes:
Shirt | XS | S | M | L | XL | XXL |
---|---|---|---|---|---|---|
FTE-estimate-weeks | week | 1 week | 2 weeks | 3 weeks | 4 weeks | 6 weeks |
- Based on the above data, what is the total FTE-estimate-weeks for the entire project?
- The team plans to start working on the product on January 8, 2024 (which is in the future). Your boss has asked for a date when you will release the product. Why is the information up to this point not sufficient to provide a projected completion date?
Question 2:Team Burn down chart (February 26, 2024)
Time has passed:
- Coding on ChordArc started as planned on January 8, 2024.
- The team started their 4th sprint on February 19, 2024. At sprint planning, the team committed to 6 user stories which they broke into 44 tasks with initial bean estimates per task based on planning poker.
- The team is currently exactly halfway through its fourth sprint. To be specific, it is first thing Monday morning, just after the daily standup, and the team just provided the scrum master (you) with their updated progress about what they did on Friday.
In the following chart:
- Tasks that were taken on by an engineer have initials in the owner column.
- The first remaining effort estimate after an engineer started on a task is underlined.
- All numbers after an engineer started on a task represent the engineer's updated estimate as of daily standup.
- A zero means the task was completed.
- The team bid the sprint based on a velocity of 420 beans for the sprint (42 beans per day).

Your tasks:
- Show a sprint table in Excel (by copying the above table) that you can use to calculate & track daily progress. You do not need to copy this to your Word/PDF document.
- In your Word/PDF, document, how many beans did the team burn down on each of the first 5 days?
- Show a sprint burndown graph (line chart) in Excel to track progress for the entire sprint. Graph both the actual daily sprint progress (for days that have passed) and ideal burndown (for all days in the sprint) based on the team's predicted velocity. Copy this to your Word/PDF file.
- Is the sprint on track, ahead, or behind? How do you know?
Question 3: Team velocity (February 26, 2024)
Here is the data from the first three completed sprints on this project:
Sprint 1:
User Story | Estimated Beans | Finished? | Remaining Beans |
---|---|---|---|
US1 | 75 | Yes | |
US2 | 48 | Yes | |
US3 | 133 | Yes | |
US4 | 21 | Yes | |
US5 | 164 | Yes | |
US6 | 99 | No | 99 |
Sprint 2:
User Story | Estimated Beans | Finished? | Remaining Beans |
---|---|---|---|
US6 | 99 | Yes | |
US7 | 51 | Yes | |
US8 | 95 | Yes | |
US9 | 57 | No | 57 |
US10 | 132 | Yes | |
US11 | 41 | Yes |
Sprint 3:
User Story | Estimated Beans | Finished? | Remaining Beans |
---|---|---|---|
US9 | 57 | Yes | |
US12 | 81 | Yes | |
US13 | 198 | No | 51 |
US14 | 141 | Yes | |
US15 | 102 | No | 77 |
US16 | 119 | Yes |
- As mentioned above, the team thinks its velocity is 42 beans per day. Using the data from the first 3 sprints, do you agree? Explain.
Question 4: Product velocity(February 26, 2024)
Using all of the data provided so far in this assignment:
- Calculate the Avengers team's backlog velocity (in FTE-estimate-weeks per sprint). Use the task-based model for calculating team velocity.
- Show a product backlog burndown graph (line chart) in Excel to track progress for the entire project. Show both per-sprint progress (for the first three completed sprints) and ideal burndown (for sprints 4 and beyond) based on the team's velocity from (B).
- Using all of the data provided so far in this assignment, what date would you provide senior leadership for when the project will be complete? Justify your answer.
