Target users
Required features
Project budget
Development timeline
Technical requirements

A clear plan helps prevent problems later in the development process.

For example, when creating an online shopping application, developers need to understand whether the system requires product listings, payment options, customer accounts, delivery tracking, and other features.

2. Software Design

After gathering requirements, developers create the software design. This stage focuses on planning how the application will work and how different components will connect.

Software design includes:

User interface design
Database structure
System architecture
Security planning
User experience planning

A good design creates a strong foundation for the entire software project.

3. Coding and Development
