Agile: For this part of the assignment, use the data from your Session 7 Team Assignment where you have two streams of three sprints each. Remember that both streams started on the same day and each sprint was roughly a month long (4 weeks). We are going to calculate the CPI at the end of Month 2 (by which time four sprints will have completed - two from the first stream and two from the second stream). Use the data/numbers you had for your six sprints (in the EXCEL template file you submitted for the Session 7 Team Assignment) to calculate the planned number of story points to be completed each week for the six sprints, and the actual number of story points to be completed each week for the six sprints. Your two-stream buildup chart (item h. in the Week 7 Team Assignment) should help here! Assign an arbitrary value of $1,000 per story point and make up some rough but realistic actual cost numbers for each week of the six sprints. You now have the data you need to construct a Double-S curve. Develop this Double-S curve in EXCEL and determine the SPI and CPI at the end.
