Your organization's test strategy states that it is desirable to use more than one method for estimating test effort. You are responsible for estimating test effort for the next project. Based on historical data, the development-to-test effort ratio is 5:3.
The initial estimate for the development effort is 450 person-days.
Which ONE of the following options corresponds to the estimated test effort using the ratio-based method?

• A.750 person-days
• B.180 person-days
• C.720 person-days
• D.270 person-days

Correct Answer: D

Comprehensive and Detailed In-Depth Explanation:
The ratio-based estimation method relies on historical relationships between development and testing effort.
Using the given 5:3 ratio:

Thus, the correct answer is 270 person-days (D).
* (A) and (C) are incorrect as they overestimate the effort.
* (B) underestimates the testing effort based on the ratio.
Ratio-based estimation helps allocate resources effectively based on past project data.

• A.Testers should contribute to all activities in the SDLC and participate in design discussions.
• B.Testers should be involved from the beginning of the SDLC to increase understanding of design decisions and detect defects early.
• C.Testers should only be involved during the testing phase.
• D.Testers' involvement is essential; developers find it difficult to be objective.
