Problem Statement
Differentiate between ‘incremental’ and ‘iterative’ models in SDLC. Provide examples of when each is appropriate.
Explanation
The incremental model builds a system by adding resolvable parts (increments) one at a time; each increment delivers user-value. The iterative model emphasises repeating development cycles (iterations) to refine and improve system continuously. For example, for a product requiring early partial deployment with core features you may use incremental. For a complex system where requirements evolve you may use iterative. Understanding these distinctions helps you suggest the right model during interviews.
