Lifecycles & Process Models
DevOps Defined
by Linda Westfall
“DevOps is the emerging professional movement that advocates a collaborative working relationship between Development and IT Operations, resulting in the fast flow of planned work (e.g., high deploy rates) while simultaneously increasing the reliability, stability, resilience, and security of the production environment” (Kim 2023).
Maintenance Management
Types of Maintenance
by Linda Westfall
Successful software products tend to have very long life spans when measured from initial release to final retirement. For example, the initial release of Microsoft Word was in 1983, so that software product has been in use for more than 30 years with no retirement in sight. However, according to Sommerville, “During their lifetime, operational software systems have to change if they are to remain useful.” [Sommerville-16]
