Waterfall Model - BogdanViblyy/Buketov GitHub Wiki

The Waterfall Model follows a step-by-step, linear process for software development. Each stage flows into the next like water over a series of ledges—once one phase is finished, the project moves on to the next without returning to the previous step.

• Key Phases Typically Include:

  1. Gathering and documenting all system requirements.

  2. Designing the system architecture and its components.

  3. Coding the software based on the design specifications.

  4. Testing the complete system for defects and issues.

  5. Deploying the finished product to users.

  6. Performing maintenance and updates after release.

• Each phase must be completed entirely before moving forward.

• Emphasizes planning, structure, and thorough documentation from the outset.

	Waterfall Model	Iterative/Incremental Models
Development Flow	Straight-line, phase-by-phase	Cyclical, repeatable steps
Adaptability	Inflexible—changing requirements is tough	Flexible—welcomes evolving needs
Feedback Timing	Late—usually during testing	Early and ongoing
Risk Management	Risks surface late in the process	Risks identified and mitigated early
Delivery Style	One final product release	Frequent deliveries of usable parts
User Involvement	Low—mainly at the beginning and end	High—feedback is continuous
Ideal For	Projects with fixed, well-understood goals	Projects with shifting or unclear goals
