Any software process must include the following four activities:
Software specification (or requirements engineering): Define the main functionalities of the software and the constrains around them.
Software design and implementation: The software is to be designed and programmed.
Software verification and validation: The software must conforms to it’s specification and meets the customer needs.
Software evolution (software maintenance): The software is being modified to meet customer and market requirements changes.
