Chapter 2 – Process Models Overview The roadmap to building high quality software products is software process. Software processes are adapted to meet the needs of software engineers and managers as they undertake the development of a software product. A software process provides a framework for managing activities that can very easily get out of control. Modern software processes must be agile, demanding only those activities, controls, and work products appropriate for team or product. Different types of projects require different software processes. The software engineer's work products (programs, documentation, data) are produced as consequences of the activities defined by the software process. The best indicators of how well a software process has worked are the quality, timeliness, and long-term viability of the resulting software product. Software Process Framework for the activities, actions, and tasks required to build high quality software Defines approach taken as software is engineered Adapted by creative, knowledgeable software engineers so that it is appropriate for the products they build and the demands of the marketplace Generic Process Framework Communication Planning Modeling Construction Deployment Umbrella Activities (applied throughout process) Software project tracking and control Risk management Software quality assurance Formal technical reviews Measurement Software configuration management Reusability management

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
