Question

What is the main problem with existing algorithmic models for cost estimation?

a.

The models are based on different sets of projects and development environments

b.

The models are not useful for large projects

c.

The models do not take into account the cost of expensive tools

d.

The models give a linear relation between software size and effort

Answer: (a).The models are based on different sets of projects and development environments Explanation:The differences between the models arise from the fact that the models are based on different sets of projects and development environments, and that each environment has its own specific characteristics which need to be taken into account when using the models.
