Ensuring System Quality and Deployment
Why is testing an essential stage in the SDLC?
What is the deployment stage in the SDLC, and what does it involve?
What is the role of maintenance in the SDLC?
What is the difference between a phased SDLC and an iterative incremental SDLC?
How does an information system in a retail business support decision-making? Provide an example.
Answers and Descriptions:
Answer: Testing verifies that the system meets requirements, functions correctly, and is free of errors, ensuring reliability and quality.
Description: This question underscores the importance of quality assurance in system development, a key learning outcome for students.

For example, it can analyze sales trends to decide which products to discount.
Description: This question requires students to apply the concept of information systems to a real-world scenario, enhancing practical understanding.
