Answer the following Questions and then, view your peers’ submissions and comment on TWO.
1) Using the following table make an argument against the use of assembly based on the functionality delivered per statement of code. Again, referring to the table, discuss why C++ would present a better alternative than C.
2) A WebApp and its support environment has not been fully fortified against attack. Web engineers estimate that the likelihood of repelling an attack is only 30 percent. The system does not contain sensitive or controversial information, so the threat probability is 25 percent. What is the integrity of the WebApp?
3) At the conclusion of a project that used the unified process, it has been determined that 30 errors were found during the elaboration phase and 12 errors were found during construction phase that were traceable to errors that were not discovered in the elaboration phase. What is the DRE for these two phases?

Quality Exercise
Compute the FP for the system:
12 external inputs (average), 24 external outputs (average), 30 external inquiries (average), 4 internal logical files (average), and interfaces with 6 different legacy systems (6 EIFs) (average).
Assume : VAF = 46
Describe steps
From past data it is known that one FP translates into 60 lines of code. How long is the estimated system size ( in lines of code)?

Estimation and Scheduling Exercises
Exercise 1:
Compute the expected values noted for the decision tree. Based on your calculations what would be your decision?
Exercise 2:
Assume you are a software project manager and that you’ve been asked to compute earned value statistics for a small software project. The project has 56 planned work tasks that are estimated to require 582 person-days to complete. At the time that you’ve been asked to do the earned value analysis, 12 tasks have been completed. However, the project schedule indicates that 15 tasks should have been completed. The following scheduling data (in person-days) are available :
Compute :
a) SPI
b) Schedule Variance
c) Percent Scheduled for Completion
d) Percent Complete
e) CPI
f) Cost Variance
