The necessities of life cycle model

There are some challenges faced by the development team while implementing the

software. Some of them are mentioned below:

· Code-reuse - Programming interfaces of present-day languages are very

sophisticated and are equipped huge library functions. Still, to bring the cost

down of end product, the organization management prefers to re-use the

code, which was created earlier for some other software. There are huge issues faced by programmers for compatibility checks and deciding how much

code to re-use.

· Version Management - Every time a new software is issued to the customer,

developers have to maintain version and configuration related documentation.

This documentation needs to be highly accurate and available on time.

· Target-Host - The software program, which is being developed in the

organization, needs to be designed for host machines at the customers end.

But at times, it is impossible to design a software that works on the target

machines.
