ALEFS is an acronym for the four stages of the software development life cycle: Analysis, Design, Implementation, and Evaluation. The term ALEFS is used to describe the process of creating a software product from conception to completion. FINALES is the seventh letter in the acronym, which stands for Evaluation. Evaluation is the final stage of the software development life cycle, where the software is tested and evaluated to ensure it meets the requirements set out in the design phase.
