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. Types of COCOMO Models Basic ... When Barry Boehm wrote 'Software Engineering Economics', published in 1981, he introduced an empirical effort estimation model (COCOMO - COnstructive COst MOdel) that is still referenced by the software engineering community. Software Engineering | COCOMO Model | Software cost estimation should be done through three stages: Basic, Intermediate, and Complete COCOMO. COCOMO-II is the revised version of the original Cocomo (Constructive Cost Model) and was developed at the University of Southern California. It is the model that allows one to estimate the cost, effort, and schedule when planning a new software development activity.
