Which concept describes a sequential software development approach with phases completed one after another?

• A. ADR
• B. Producible
• C. Waterfall Approach
• D. Lean Manufacturing

Answer: (C)

The concept tested is a linear, plan-driven software development lifecycle where work moves through distinct phases in a fixed order. The Waterfall Approach exemplifies this: you start with gathering and agreeing on requirements, then move to design, then implementation, followed by verification (testing) and deployment, and finally maintenance. Each phase is completed and approved before the next begins, with little to no overlap or revisiting of earlier phases. This gives clear milestones and documentation, which can be advantageous when requirements are stable and changes are costly or discouraged. Other options don’t describe this strict sequence. Architectural Decision Records capture decisions about the system’s architecture rather than describing a lifecycle flow. Producible isn’t a recognized software lifecycle model. Lean Manufacturing is a manufacturing concept focused on eliminating waste and improving flow; while it can influence software practices, it isn’t a single, linear phase-by-phase development approach.
