The provision in this step is to make a user need and business goal transform into a technical blueprint, that emphasizes performance, usability, and maintainability. Development basically involves the construction of models, diagrams, and prototypes to define the structure of the system; it guides the developers in code and database generation.

This is guided by different design methodologies like object-oriented and component-based designs that control how the system components are organized to facilitate easy development, testing, and maintenance.

It ensures team collaboration, aligning all members on the project’s goals and architecture. Likewise, an application with effective design could be changed over time to meet an evolving requirement as new technologies are brought on stream.
