Why is it beneficial and often necessary to have a structured design approach to computer program development?

Answer 1

Structured designing is clean. It is hard to imagine computer programming without thinking of it as being structured. Structure or a structured approach is built into the very concept of programming. By adding your own structure, you can, as a programmer, add order, power and usefulness to your program.

Modern programs are complex. The computers that manipulate them are very fast. A small mistake can go far in destroying value ( or maybe the entire human race! ). So be clear, be organised and be simple. Even the most complex tasks and algorithms can be implemented with utmost simplicity if you keep on breaking them down to logical levels.

Good Luck!

Answer 2

It allows many programmers who share the same understanding of how programs should be designed to work on and understand large projects without the need to constantly waste time explaining why they have done things a certain way.

Answer 3

To create anything of any complexity, you first create a design for it. Once you have a design, then it becomes a lot easier to create whatever it is you are creating. This applies just as much to a computer program as it does to creating a car or building a house. Just like a builder cannot build a house without a design created by an architect, a detailed program cannot be written without a design. Without a design you are left asking yourself what you want to do and and what to do next. A design thinks through all these questions and answers them so that when you sit down to write the program you know what needs to be done and how you are going to do it. That makes writing the program a lot easier and a lot faster.
