Question 34/78

Calculate the measurement error SD for the following estimates done using three point estimation technique- Most optimistic effort (a) -120 person days Most likely effort (m) -180 person days Most pessimistic effort (b) - 240 person days

A. 20

B. 180

C. 197

D. 120

Correct Answer: A

A test-first approach involves writing tests before writing the code. In this approach, initially, the tests fail because the corresponding functionality is not yet implemented. Afterward, the code is written or modified to make the tests pass. This cycle is repeated iteratively. This method ensures that the code is developed based on predefined tests and helps in identifying issues early in the development process.
