What are the misunderstanding arise in software development

Some of the common misunderstandings regarding software development are given below.

1.  Correcting errors is easy. Though changes in the software are possible, though, making changes in large software is very difficult task.

2.  By proper development of software, it can function perfectly at first time. However, theoretically, it seems correct, but practically software undergoes many development/testing/coding passes before becoming perfect for working.

3.  Loose objective definition can be used at starting point. Once a software is developed using loose objective, changing it for specific objectives can require complete change.

4.  More manpower may be added to speed up development. Software is developed by well-coordinated teams. Any person joining it at a later stage mayrequire extra efforts to understand the code.
