Artificial intelligence can be used throughout the software development life cycle (SDLC) to improve various processes. This includes using AI to help with requirements analysis, defining requirements, designing product architecture, developing code, testing, and deployment/maintenance. Some popular SDLC models that can benefit from AI integration include the V-Model, waterfall model, iterative model, and spiral model. By automating tasks with AI, these models may see increased efficiency, quality, and reduced costs and timelines for software projects.
