In general, SDLC has five core phases in any of the models. They are listed and diagrammatically represented as follows:

• Requirement phase
• Design phase
• Implementation phase
• Testing phase
• Production phase

In the requirement phase, the requirements are collected based on the needs of the business stakeholders. The design phase describes the structure and components of the new system as a collection of modules and subsystems. Implementation is the programming phase in which the design is converted into reality. The testing phase is used to certify the functionality of the developed application. Production is the final phase to roll out the system for end customer usage.
