What are the various SDLC models?
"From what I learned in university, there are five primary SDLC models which include Agile, Spiral, Waterfall, Iterative and V-shaped. Since my focus is not on IT business analysis, I did not perform a deep dive into these; however, I do understand V-shaped analysis and the fact that it is an extension of the waterfall method."
SDLC stands for Software Development Life Cycle, a concept that IT Business Analysts often use. There are various SDLC models, including Agile, Waterfall, Spiral, Iterative, and V-Shaped. Display to the interviewer that you understand the variances between these models by briefly discussing their differences.
"The SDLC models which I am most familiar with include Agile and Spiral. I like agile because it encourages adaptation, continuous improvements and offers flexible responses to change. With Spiral, it's more risk-driven, which is also a fascinating method in which to work. The others include Waterfall, Iterative, and V-shaped, which I am less familiar with but keen on learning."

SDLC models are waterfall, agile, and spiral. I think Agile is very important, as it gives us a reason to adapt and make changes on the spot.

Nice job! These questions may come up in an interview so that the interviewer can see if you have the correct knowledge base/fundamentals for a BA role.
