Differences Between the Basic, Intermediate, and Detailed COCOMO Model

Factors	Basic COCOMO	Intermediate COCOMO	Detailed COCOMO
Equation	Effort = a * (Size)^b	Effort = a * (Size)^b * EAF	Effort = a * (Size)^b * EAF * Mode Factors
Focus	Size-based estimation	Incorporates additional cost drivers for complexity	Extensive consideration of various factors
Size Metric	Thousands of Lines of Code (KLOC)	Same as Basic COCOMO (KLOC)	Same as Basic and Intermediate COCOMO (KLOC)
Complexity Factors	Not considered	Added cost drivers categorized into Product, Platform, and Personnel	Expanded set of 17 cost drivers
Cost Drivers	N/A	15 cost drivers for Product, Platform, and Personnel	17 cost drivers, including those from Intermediate COCOMO
Adjustment Factor	N/A	EAF (Effort Adjustment Factor) based on cost drivers	EAF multiplied by mode-specific effort factors
Development Modes	N/A	N/A	Differentiates between Organic, Semi-detached, and Embedded
Project Characteristics	Basic software development only	More comprehensive, considers development environment	Wide range of project-specific characteristics
Levels of complexity	Although it overlooks numerous project-specific considerations, Basic COCOMO offers a straightforward estimate based on size.	In order to increase estimation accuracy, Intermediate COCOMO provides cost elements that categorise aspects impacting development.	Detailed COCOMO takes into account several design elements and development approaches while also expanding cost variables.

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.
