COCOMO model in Software Engineering - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does COCOMO stand for?

COCOMO stands for Constructive Cost Model. It is a method used to estimate the cost, effort, and time required to develop software.

beginner

Name the three levels of the COCOMO model.

The three levels of COCOMO are:<br>1. Basic COCOMO<br>2. Intermediate COCOMO<br>3. Detailed COCOMO

beginner

What is the main input used in the COCOMO model to estimate effort?

The main input is Lines of Code (LOC) or thousands of lines of code (KLOC) expected to be written in the software project.

intermediate

How does the Intermediate COCOMO model improve upon the Basic COCOMO?

Intermediate COCOMO adds cost drivers or factors like product reliability, complexity, and team experience to adjust the effort estimate, making it more accurate than Basic COCOMO.

intermediate

What is the purpose of the Detailed COCOMO model?

Detailed COCOMO breaks down the project into smaller components and applies cost drivers to each part, providing a very detailed and precise estimate of effort and schedule.

What is the primary measure used by COCOMO to estimate software development effort?

A Number of developers

B Lines of Code (LOC)

C Project budget

D Number of features

COCOMO uses Lines of Code (LOC) as the main input to estimate effort.

Which COCOMO model includes cost drivers to adjust estimates?

A Intermediate COCOMO

B Basic COCOMO

C Detailed COCOMO

D None of the above

Intermediate and Detailed COCOMO use cost drivers to refine effort estimates.

What does the Detailed COCOMO model do differently compared to the Basic model?

A Breaks project into parts and applies cost drivers to each

B Uses only LOC without adjustments

C Ignores project complexity

D Estimates only schedule, not effort

Detailed COCOMO divides the project and applies cost drivers to each part for precise estimates.

Which of the following is NOT a factor considered in Intermediate COCOMO's cost drivers?

A Product reliability

B Team experience

C Software complexity

D Number of programming languages used

Number of programming languages is not a typical cost driver in Intermediate COCOMO.

COCOMO is primarily used to estimate which of the following?

A Software development effort and cost

B User satisfaction

C Hardware requirements

D Marketing budget

COCOMO estimates the effort and cost needed to develop software.

Explain the three levels of the COCOMO model and how they differ in estimating software development effort.

Think about how each level adds more detail and factors to improve accuracy.

Describe how cost drivers influence the effort estimation in the COCOMO model.

Consider why just counting lines of code might not be enough.
