Software Lifecycle Processes as a Projection of the Fourth Dimension of a System

Let's talk about software lifecycle models, processes, and stages, covering Waterfall, RUP, Spiral, Agile, and Scrum (I suppose it will be scandalous). What is hidden behind the famous quote by David Dischave: “What continues to amaze me is why the word 'Waterfall' is still used to describe a methodology that doesn’t exist.” (A brief historical dive.). 

However, the main focus of the talk will be on the lifecycle of systems and software, the description of lifecycle models in systems and software engineering standards, and how these standards can help us when applied. Why a reference process model doesn’t dictate methodology or technology. And why it’s important to understand the separation of processes into organizational and technical groups.
