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."

"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 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."
