Final answer:
The fully plan-driven life cycle referred to in the question is the Predictive life cycle, which is known for its linearity and rigid structure, making it suitable for projects with clear, stable requirements.
Step-by-step explanation:
The life cycle that is also known as fully plan-driven is Predictive. A predictive life cycle, sometimes referred to as the waterfall model, is a project management approach where each phase of the project's life cycle is planned in advance and executed in a linear sequence.
This type of life cycle is contrasted with Adaptive (or Agile) methodologies, which are more flexible and iterative, and Incremental design, which involves building a product or system piece by piece.
The key characteristics of a Predictive life cycle include detailed documentation, clearly defined scope, and a sequence that often does not overlap. As a result, changes in scope or direction are less accommodated once the project is underway. While this model can be quite rigid, it is suitable for projects with clear requirements and a stable environment where change is minimal.
