Which phase is typically the first in a life cycle model?

The first phase in a life cycle model is the concept phase. This phase is crucial as it lays the groundwork for the entire project. During the concept phase, initial ideas are generated, feasibility studies are conducted, and the overall vision for the system is formulated. Stakeholders identify requirements and assess the potential value of the project, helping to decide if it should move forward into more detailed planning and development.

This phase is foundational because it guides subsequent phases, ensuring that the project objectives align with stakeholder needs and expectations. It allows for early identification of risks and opportunities, which can significantly influence the success of the project as it progresses through development, utilization, and support phases. The emphasis on understanding needs and formulating a clear concept helps set up a project for success in later stages.
