• Software engineering is the institution of a sound engineering principle to get an economical package that's reliable and works for real machines.
  • Software engineering is the associate application of a scientific, disciplined, and quantitative approach to the developer, operation, and maintenance of packages.
  • Software engineering could be a disciplined whose aim is that the production of the fault-free package that satisfies the user's desires which are delivered on time and inside the budget.

By these definitions, we can say that the aim or goal of software engineering is:-

  • High quality
  • Low cost
  • Deliver in time
  • Reliability
  • Full fill the necessities
  • Complet the user desires
  • Software engineering provides SRS
  • Increase productivity
  • Maintainability

Factor/Feature concerned within the emergence of package engineering:-


Need of software engineering:-


The need for package engineering arises owing to a better rate of amendment in user needs and therefore the atmosphere on that the package is functioning.
  • Large package - it's easier to make a wall than to a house or building, likewise, because the size of the package becomes giant engineering should step to allow it a scientific method.
  • Scalability- If the package method weren't supported scientific and engineering ideas, it'd be easier to re-create a new package than to scale associate existing one.
  • Cost- because the hardware trade has shown its skills and big producing has lower down the value of pc and electronic hardware. however, the value of the package remains high if the correct method isn't custom-made.
  • Dynamic Nature- The continuously growing and adapting nature of the package vastly depends upon the atmosphere within which the user works. If the character of the package is often dynamical, new enhancements have to be compelled to be tired of the prevailing one. this is often wherever package engineering plays a decent role.
  • Quality Management- the higher method of package development provides a higher and quality package merchandise.
