Answer to Question #98900 in Software Engineering for Aliasgar Ansari

Question

How it is difficult to estimate system development cost accurately during early stages of the project ?

Answer 1

It is difficult for projects with vague requirements, missing information or slow or unproductive communication with the customer because you may not get enough information about what specific skills you should have and how much time will be required to successfully complete the project, what functions should the software have.

However, if everything is well and clearly discussed and the customer is ready to share his views on what she or he wants to get, the approximate size of code is discussed, the cost evaluation becomes much easier.

And as usual, very important information that will help to estimate the project correctly is the reputation of the customer.
