This is a big problem and very small points.
Changing some code without affect on another code depends on your software architecture. If you design your software into subsystem, small module or use case approaches. When your customers change their requests you just change code of only module or only subsystem.
Managing requirement is a vital problem in software development. Sometime requirement changing make software projects fail because this change make software architecture change and this change is beyond the cost of time and money.
With some hints, I hope they are helpful for you.

Subsystem is a part of your system which can be seperate each others. Takw example a software contains 4 subsystem A,B,C,D. A,B,C,D  most depend each others. So you can change code of A without affect on B,C or D.
Use case is a fuction of program which is viewed by user. Use case approach is a method to design a software which is coded to solve every use cases seperately. So, when user requests changes, some use cases are changed not all of them.

Generally these processes will depend upon your organization and that would mandate how you go about doing it.
