● ● Software Process A software process can be characterized as follows: A common process framework is established by defineing a small number of framework activities that are applicable to all software projects,regardless of their size or complexity. A number of task sets -each a collection of software engineering work tasks,project milestones,work products,and quality assurance points -enable the framework activities to be adapted to the characteristics of the software project and the requirements of the project team. Umbrella activities such as software quality assurance. software configuration management,and measurement-overlay the process model.Umbrella activities are independent of any one framework activity and occur throughout the process
