The Structured Approach - Software Design and Development

The issue to be resolved has to be identified. This is important in determining the end product's purpose and function

Identify what data is given to the system for processing (input), and the information that the system gives back after processing (output)

Decide how the product will be developed

Actually create the product, as per the method made in the 'Plan' process

Ensure the product is functioning and performing as expected

Make changes to the product as necessary

Thank you for your attention!

And one more thing...

Conclusion

• Suited for large projects
• Broken up into modules
• Follows a set of processes in a linear fashion

Overview

• Generally used in large projects
• Composed of various stages (modules)
• Each stage / module is fully completed, then work commences on the next stage / module
• This is continued until all modules are completed and are integrated to form the completed project

Processes

• Define the problem
• Define input and output
• Plan
• Build
• Check
• Modify
