Correct Answer - Option 4 : Size, effort and duration based on the size cost of the software
COCOMO: It is a procedural cost estimate model for software projects and often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time, and quality.
The key parameters which define the quality of any software products, and are also an outcome of the Cocomo are primarily Effort and Schedule:
Effort: Amount of labor that will be required to complete a task. It is measured in person-months units.
Schedule: It simply means the amount of time required for the completion of the job, which is, of course, proportional to the effort put. It is measured in the units of time such as weeks, months.
The formula used for the cost estimation of the basic COCOMO model is:
E = a (KLOC)b
Time = c (Effort)d
Person Required = Effort/time
