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".
The computer science discipline concerned with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting. Software Engineering is an approach to developing software that attempts to treat it as a formal process more like traditional engineering than the craft that many programmers believe it is. We talk of crafting an application, refining and polishing it, as if it were a wooden sculpture, not a series of logic instructions. The problem here is that you cannot engineer art. Programming falls somewhere between an art and a science.
Software Engineering: Software Engineering has come to mean at least two different things in our industry. First of all the term "software engineer" has generally replaced the term "programmer". So, in that sense there is a tendency to extrapolate in people's minds that Software Engineering is merely the act of programming. Secondly, the term "Software Engineering" has been used to describe "building of software systems which are so large or so complex that they are built by a team or teams of engineers", as was used in Fundamentals of Software Engineering by Ghezzi, Jazayeri, and Mandrioli. Yet, there is increasing evidence that many of the processes we have been developing for large groups of engineers also apply to the best practices of even individual engineers.Therefore, for the purpose of the Software Engineering Yellow Pages (SEYP), Software Engineering is intended to mean the best-practice processes used to create and/or maintain software, whether for groups or individuals, in attempt to rid ourselves of the usual haphazard methods that have plagued the software industry. This would include subjects like Configuration Management, Project Planning, Project Tracking, Software Quality Assurance, Risk Management, Formal Inspections, etc.Systems engineeringis an interdisciplinary field of engineering that focuses on how complex engineering projects should be designed and managed. Issues such as logistics, the coordination of different teams, and automatic control of machinery become more difficult when dealing with large, complex projects. Systems engineering deals with work-processes and tools to handle such projects, and it overlaps with both technical and human-centered disciplines such as control engineering and project management.System engineering deals with all aspects of computer-based system development.Software engineering is a part of system engineering.System engineering is to identify the roles of hardware, software, people, database and other system elements involved with that system which is going to be developed.Software engineering is to tell the practicalities of developing and delivering useful software.
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.
While most people think of a "software engineer" only as the person who sits around and writes code, this job is actually much more complex. Software engineers must see a software product through its whole lifecycle. This starts with some idea a customer has, goes through multiple stages each of: gathering requirements, setting formal specifications, implementation, testing, and maintenance.
Philosophy is a treasure of rich creativity with informal and formal ideas. Studying philosophy is a complete wisdom itself, that is used practically in our daily lives.

Formal Technical Review
Formal and informal communication serve different roles. Formal communication takes longer to develop and is often used to document procedures, requirements, and policies. Informal communication smoothes the day-to-day running of the organization.

It's both formal and informal. It depends on how you say it. If you say "Adiós, señora." it's formal. If you say "Adiós, amigo." it's informal.
