iSQI CTAL-TM_Syll2012 Exam - Topic 3 Question 55 Discussion

Actual exam question for iSQI's CTAL-TM_Syll2012 exam
Question #: 55
Topic #: 3
[All CTAL-TM_Syll2012 Questions]

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? K3 3 credits

The team effort seems proportional to the defects found, though.

I feel like option D could be true since we found more defects than expected, but I'm not confident about the defect density comparison with past projects.

I practiced a similar question where we had to compare defect rates, but I can't recall if the number of LOC delivered can be assumed to be double the planned amount.

I'm not entirely sure, but I think the defects found should relate to the effort put in by the team. Maybe option B is correct?

I remember that defect density is calculated based on LOC, so if we have 20000 LOC and found 797 defects, it might indicate a higher density than before.

Based on the information provided, I think option D is the correct answer. The data shows the project delivered more LOC than planned, and the defect density is higher than the past projects.

Okay, let's break this down step-by-step. We have the historical data, the project manager's estimates, and the actual results. I think we can use that to determine the correct statement.

Okay, let me see. The key seems to be that the employees are trying to avoid detection, so they're keeping the disbursement sizes low. I'm leaning towards A or B, but I'll double-check the options again.

Okay, I've got this. The key is using the Apply Sales Credit Concurrent program, which is option B. That's definitely the way to go here.

Haha, the project manager must be using the same estimation techniques as my uncle's garage construction business. As for the answer, I'm going with D. The numbers just don't add up any other way.

Hold on, did they just throw in a joke about the project manager's estimates? That's hilarious! As for the actual answer, I'm leaning towards option D as well. The numbers just don't add up otherwise.

I'm not sure about this one. Option B seems plausible, but the question specifically says to base the answer on the information provided, and that doesn't mention anything about the number of defects being proportional to the development team effort.

Hmm, this is a tricky one. Based on the information provided, I think option D is the correct answer. The number of defects found during system testing is much higher than what was expected, suggesting that more LOC than planned were delivered with a higher defect density.
