MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Software project estimation can never be an exact science, but a combination of good historical data and systematic techniques can improve estimation accuracy.

Detailed explanation-2: -Three-point estimating This technique takes a mathematical approach to estimation, allowing project managers to be far more accurate with their estimates. The technique uses three ranges to work out estimation probabilities: the most optimistic estimate, the most likely estimate and the most pessimistic estimate.

Detailed explanation-3: -5. Parametric Model Estimation. Project estimation is the process of predicting the most likely amount of resources needed to complete a project. There are many different techniques that can be used for estimation, but the parametric model is one of the most accurate.

Detailed explanation-4: -Empirical Estimation Technique – Empirical estimation is a technique or model in which empirically derived formulas are used for predicting the data that are a required and essential part of the software project planning step.

Detailed explanation-5: -Empirical Estimation Technique – In this technique, an educated guess of project parameters is made. Hence, these models are based on common sense.
