As far as i see, this "formal transformation" model only exists on the CAPE (Caribbean Advanced Profiency Examination) Syllabus under SDLCs and nowhere else... Good luck finding info on this. I have been searching for 2 years.
The waterfall development model has its origins in the manufacturing and construction industries, highly structured physical environments in which after-the-fact changes are prohibitively costly, if not impossible. Since no formal software development methodologies existed at the time, this hardware-oriented model was simply adapted for software development.
Formal requirements are the software features that the developers are contractually obligated to implement in the software. It is usually designated as a "shall" statement as in "X shall do this". Informal requirements are the software features that are nice to have but would not be a breach of contract if the developers failed to implement it in the software. These requirements may have have the word "will" as in "X will do this".
A software process model is an abstract description of a piece of software. The software itself is an actual program (or set of programs) which can run on your computer.
No, water fall model in software engineering is not a flexible model . Waterfall model have certain limitations like we can not go back into earlier phase .
The RAD model, also known as the Rapid Application Development, is a linear software for creating prototypes. The Waterfall model is a sequential software.
This is one of many software development models. Use this model, the development only need to convert the requirement from customer to the model language then use automated tool to generate executable program. To do this, the tool do the transformation has to general enough to describe the problem exactly. This is still not popular method to develop business application today. But in future it may be useful when there are many standard business case are defined

no
The waterfall model is a sequential software development process, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design (validation), Construction, Testing and maintenance. The unmodified "waterfall model". Progress flows from the top to the bottom, like a waterfall.It should be readily apparent that the waterfall development model has its origins in the manufacturing and construction industries; highly structured physical environments in which after-the-fact changes are prohibitively costly, if not impossible. Since no formal software development methodologies existed at the time, this hardware-oriented model was simply adapted for software development. Ironically, the use of the waterfall model for software development essentially ignores the 'soft' in 'software'. The first formal description of the waterfall model is often cited to be an article published in 1970 by Winston W. Royce (1929-1995), although Royce did not use the term "waterfall" in this article. Ironically, Royce was presenting this model as an example of a flawed, non-working model (Royce 1970). This is in fact the way the term has generally been used in writing about software development-as a way to criticize a commonly used software practice.

Waterfall model is the best software life cycle model.
All industries are using the waterfall model for software development.
