4. Testing

Testing is a vital phase in the SDLC, where the software product is evaluated for defects, bugs, and performance issues. Various types of testing, such as unit testing, integration testing, and user acceptance testing, are conducted to ensure that the software product is reliable and meets the quality standards.


5. Deployment

After successful testing, the software product is deployed to the production environment, making it available to end-users. Deployment can be a complex process, especially for large-scale software products, and may involve rolling out the product in phases to ensure smooth adoption.


6. Maintenance

The final phase of the SDLC is maintenance, where the software product is monitored and updated to address any issues or new requirements that arise. Maintenance is essential for the long-term success of the software product, ensuring that it continues to meet user needs and adapts to changes in technology and business environments.


Types of Software Products in Software Engineering

Software products can be categorized into different types based on their purpose, target audience, and delivery model. Understanding these categories is important for software engineers to tailor their development approach accordingly.
