what is software engineering?
using proper theories, tools, methods(organized and systematic), constraints to develop high quantity software.
4 layers
Tools, method, process, quality focus.
Why important?
large scale projects are hard to finish in time properly because of time, budget, disaster, etc. guiding scientific principles and universally applicable methods can reduce practice and frequent failures.
General issues that affect software
