What is the first step in the software development lifecycle (SDLC) model?

The first step in the software development lifecycle (SDLC) model is planning. This step is critical as it sets the foundation for the entire development process. During the planning phase, project goals are defined, requirements are gathered, and stakeholders identify what they want the software to achieve. This phase involves feasibility studies, budget considerations, and timeline estimations, which help in determining the overall scope and direction of the project.

In addition, a well-thought-out planning phase helps to establish a clear understanding among team members and stakeholders, ensuring that everyone is aligned on objectives and expectations. This careful preparation is essential to mitigate risks and guide subsequent phases of software development, such as design, implementation, and testing. Proper planning ultimately contributes to a more efficient workflow and a higher quality final product.
