- 5. Software engineering is an engineering branch associated with development of software product using well-defined scientific principles, methods and procedures. The outcome of software engineering is an efficient and reliable software product. Software project management has wider scope than software engineering process as it involves communication, pre and post delivery support etc. Software Engineering Home
- 6. Let us first understand what software engineering stands for. The term is made of two words, software and engineering. Software is more than just a program code. A program is an executable code, which serves some computational purpose. Software is considered to be collection of executable programming code, associated libraries and documentations. Software, when made for a specific requirement is called software product. Engineering on the other hand, is all about developing products, using well-defined, scientific principles and methods.

- 8. (IEEE (Institute of Electrical and Electronics Engineer (1) The application of a systematic, disciplined, quantifiable approach to the development , operation and maintenance of software; that is, the application of engineering to software. (2) The study of approaches as in the above statement. Fritz Bauer, a German computer scientist, defines software engineering as: Software engineering is the establishment and use of sound engineering principles in order to obtain economically software that is reliable and work efficiently on real machines. Software Evolution This includes the initial development of software and its maintenance and updates, till desired software product is developed, which satisfies the expected requirements. IEEE defines software engineering as
- 9. Evolution starts from the requirement gathering process. After which developers create a prototype of the intended software and show it to the users to get their feedback at the early stage of software product development. Software Evolution
- 10. Software paradigms refer to the methods and steps, which are taken while designing the software. There are many methods proposed and are in work today, but we need to see where in the software engineering these paradigms stand. These can be combined into various categories, though each of them is contained in one another: Programming paradigm is a subset of Software design paradigm which is further a subset of Software development paradigm. Software Paradigms
- 11. This Paradigm is known as software engineering paradigms where all the engineering concepts pertaining to the development of software are applied. It includes various researches and requirement gathering which helps the software product to build. It consists of – Requirement gathering Software design Programming Software Development Paradigm
- 12. Software Design Paradigm This paradigm is a part of Software Development and includes – Design Maintenance Programming Programing Paradigm This paradigm is related closely to programming aspect of software development. This includes – Coding Testing Integration Software Design Paradigm & Programming Paradigm
- 13. A software product can be judged by what it offers and how well it can be used. This software must satisfy on the following grounds: Operational Transitional Maintenance Operational This tells us how well software works in operations. It can be measured on: Budget Usability Efficiency Correctness Functionality Dependability Security Safety Characteristics of good software
- 14. Transitional This aspect is important when the software is moved from one platform to another: Portability Interoperability Reusability Adaptability Maintenance This aspect briefs about how well a software has the capabilities to maintain itself in the ever-changing environment: Modularity Maintainability Flexibility Scalability Characteristics of good software
