Which SDLC model is best?

Each of the SDLC models offers a unique process for the variety of project challenges that can be encountered. Finding the right one depends heavily on not just the expected outcome, but the parameters by which the project is executed.

Still, the waterfall model is suitable for small projects where it is easy to gather the product requirements, whereas an agile model is suitable for larger projects where clients are involved during every phase of the software development process.
