Based on the historical data of 5 past and similar projects, you have calculated these average
numbers of defects detected in system testinG.
– For each 10000 LOC (lines of code), 200 defects
– For each person-month of development team effort, 49 defects
You want to use this information to perform estimation for a new project.
The project manager tells you that he/she has estimated 20000 new LOC for this new project.
Four developers work for four months on this project before system testing.
During system testing, 797 defects are discovered.
Assume that the system test of this new project is using the same amount of work as spent in the
past projects.
Based on this information only, which of the following statement is certainly true about this project?
A.
The code for the new project contains a higher defect density than the code of the past projects
B.
The number of defects found during the system test phase on the new project is approximately
proportional to the development team effort
C.
40000 LOC have been delivered to system testing (against the 20000 LOC planned by the
project manager)
D.
More LOC than planned have been delivered to system testing with a higher defect density
than the past projects
