<p><em>The System Life Cycle or commonly known as the System Development Life Cycle (SDLC) is one of the software development methodologies. Software development (software engineering) is a development based on engineering principles or concepts that aims to create software that has commercial value, is reliable, and runs efficiently on machines. In this study, the author conducted a literature study of several studies related to the context of writing from credible sources. This study aims to reproduce previous research related to the risks in SDLC implementation by explaining in general the risks that exist in software development with the SDLC methodology on the models that exist in this methodology. The results showed that there were several problems and risks associated with the common SDLC methodology, such as rigor, human error, and time constraints. </em></p>
