Q. Explain Intermediate and Detailed COCOMO model?

Intermediate COCOMO calculates software development effort as function of program size and a set of cost drivers that include subjective assessment of hardware, product, personnel and project attributes. This extension considers a bunch of four "cost drivers" every with a number of subsidiary attributes:-

• Product attributes

• Required software reliability
• Size of application database
• Complexity of the product

• Hardware attributes

• Run-time performance constraints
• Memory constraints
• Volatility of the virtual machine environment
• Required turnabout time

• Personnel attributes

• Analyst capability
• Software engineering capability
• Applications experience
• Virtual machine experience
• Programming language experience

• Project attributes

• Use of software tools
• Application of software engineering methods
• Required development schedule
