COCOMO Model
Q.1: What is the COCOMO model?
Answer:
COCOMO (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code. It is a procedural cost estimate model for software projects and is often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time, and quality. It was proposed by Barry Boehm in 1981 and is based on the study of 63 projects, which makes it one of the best-documented models.

Q.2: What are the Expressions of the Basic COCOMO Model?
Answer:
E=a x (KLOC) b
P=effort/time
D=c x (Effort) d
Here, E is the effort in person-months, P is the total count of persons required to finish the project, D is the time of development in months, and KLOC denotes the product’s size, i.e., the kilo lines of code. All the constants a, b, c, and d have varying values for different models.
Q.3: What are the Expressions of the Intermediate COCOMO Model?
Answer:
E=ax(KLOC)b x EAF PM
D=cx(Effort)d
Here, E is the effort in person-months, KLOC denotes the product’s size, i.e., the kilo lines of code, and EAF is the Effort Adjustment Factor calculated by multiplying the values of different parameters of different cost drivers.
Q.4: What are the Three Types of Projects in COCOMO?
Answer:
COCOMO model techniques divide software projects into three categories: organic, semi-detached, and embedded. These are categorized on the basis of the sizes of teams and the project, developer experience, the developing environment, innovation, and deadline.
Differences Between the Basic, Intermediate, and Detailed COCOMO Model
In the realm of software engineering, the Construction Cost Model (COCOMO) is a significant technique for estimating software costs that has been used for many years. To estimate the time, effort, and resources needed for software development to be successful, COCOMO offers an organized method. For better decision-making, enhanced project planning, and efficient resource allocation, project managers, developers, and stakeholders can use this effective tool.
