One advantage of bottom-up design is the ability to reuse programs to solve a wide range of problems. For example, a program to sort a list can be used repeatedly in many different programs for a variety of purposes. Additionally, if the applications functionality or specifications change, the impact may not be as great as it would be if a top-down approach were taken. Since a programmer using the bottom-up approach does not need to have a complete description of all functionality needed to solve a problem, changes to portions of the program are easier to make.

Testing is also easier using the bottom-up design approach. Components of a program can be tested separate from other components, and the number of testing cycles is reduced.

The bottom-up approach is becoming more important as programs become more complex or even open-ended. For these types of programs, the top-down...
