Software Development Life Cycle (SDLC) is the foundation of all software development methodologies that include different processes like requirement preparation, budget estimation, documentation writing, design & development, testing, maintenance, and audit. 

There are 7 phases of the SDLC: 

• Planning - a team of developers and consultants determines project goals and a detailed plan including feasibility assessment, project plan creation, and systemic identification for development 
• Analysis - the client and development team analyze the end-consumer business requirements and convert the project goals into a framework that the organization wants to build, through business requirement collection detailed analysis implementation, and processes diagram design 
• Design -  Desired features and functionalities of a software application are hashed out in the design phase -  including business rules, screen layouts, pseudo-code, and other documentation defining the components of the software. This phase usually comprises of  IT Infrastructure Designing, System Model Designs, Technical Designs, User Interfaces, and Marvel Prototype
• Development - Developers write the code at the backend of a software application so that all the components finalized are remodeled into a functioning framework, through two primary processes - IT Infrastructure Development and Code and Database Development 
• Testing - All code elements are integrated and hosted in the testing environment to check the system for bugs, defects, and errors to test the system’s functionalities. This phase involves test cases creation and execution 
• Deployment - The system is brought to the real-life environment where the user starts operating the system and involves placing all data and components in the production environment 
• Support and Maintenance - Corrections, changes, and enhancements can be made to ensure that the system will perform after the updates and meet the business goals. Supporting the system users, regular maintenance and updates are essential to manage and upgrade the software from time to time so that it runs seamlessly in the future.
