In Scrum project methodology, the team decides itself on how the work should be done. However in XP, it comes with the standard set of practices and the work practice is based on these core standards. Scrum methodology is mostly concerned about productivity. However, XP methodology is concerned all about engineering.

Here's a quick and easy way to differentiate agile, DevOps, and CI/CD: Agile focuses on processes highlighting change while accelerating delivery. CI/CD focuses on software-defined life cycles highlighting tools that emphasize automation. DevOps focuses on culture highlighting roles that emphasize responsiveness.

SDLC - Waterfall Model. ... The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete.

The way that I was taught, there is a clear difference between the two. A software process model is an abstract representation of a process methodology. ... A software process methodology is a specific way of conducting a software project. These are things like the Rational Unified Process and Scrum.

A waterfall approach is where requirements are documented and approved before moving to a design phase, followed by a build phase and finally a testing phase. There is nothing in PRINCE2 which prescribes such a waterfall approach. ... PRINCE2 manages such changes to project scope using its change control approach.
