The Nature and Scope of Software Engineering

Software engineering looks into designing and implementing software applications and also modifying them so that they are better suited to client requirements. It is one of the most important aspects of software development and is a must to be implemented in any organization that has undertaken software development activities. Though a basic engineering degree in computer science is enough to work as a software engineer, a better advantage would be to have a license. In the U.K, it is the British Software Society that licenses software engineers. In Canada, they have the Professional Engineer (P.Eng) designation, though as per the law, there is no necessity to have such qualifications.

There are several sub-disciplines into which can be divided. These are software requirements, software design, software development, software testing, and software maintenance and software configuration management. The need for software engineering came about because of computing history. Problems such as the ‘software crisis’, ‘complexity barrier’ hindered progress which were in course of time resolved through various techniques that came to encompass as a whole.

While a software engineer also takes on the role of a programmer, a programmer will not take on the role of an engineer, which basically involves dealing with theoretical constructs of software and hardware development. There are many job domains and these include programmers, hardware administrators, network specialists and system testers. The overall purpose of this is to develop and maintain systems that work reliably and which can meet up to the expectations of customers and which process information in an efficient manner. A point to be noted about this field is that though it incorporates programming, it also looks into factors such as understanding client requirements, designing principle and testing to ensure that the application conforms to standards that have been set.

Understanding Software Engineering

It is a systematization of the process of software development to ensure the best solution most economically. Its goal is to produce high quality software at low rate.

Software Engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation and maintenance of software. A typical software development project will need to go through the phase of Analysis, Design, Programming, Testing and Implementation. Software Project Management (SPM), Software Quality Assurance (SQA) and the use of Computer aided Software Engineering (CASE) would run parallel with the other phases and finally comes the maintenance phase. It is always said that more than 80% of the costs go towards maintenance of the software.

Software Methodology

It is a step by step plan for implementing a method using certain tools and procedures. It often describes the entry criteria, exit criteria and checkpoint for each of the activities or components in software engineering. Some of the popular methodologies today are based on structure techniques or information engineering or object-oriented techniques. Methodology selection depends on the nature of the project, the type of application, the tools proposed to be used and the kind of controls and documentation that would be required.

Waterfall, Prototyping, Spiral, Rapid Application, Stepwise Refinement, Industrial and military standards, Assembly by reuse, Application generation, Continuous transformation and Knowledge based software automation are some of the popular methodologies.

What factors would influence the choice of model for software development?

It depends on the nature and size of application, whether it is an in-house development or development through an external agency, the availability of various tools and resources, time frame and budget, etc.

Who is Software Engineer?

A software engineer is someone who applied engineering principles in the co-operative development of software. A good software engineer should not only generate computer programs but also learn the skills to produce good documentation, database and operational procedures for the computer system. He should be well defined about the components or modules of software engineering.

Become a Computer Software Engineer

To help meet this demand, students seeking Computer Careers will need at least a bachelor’s degree in computer engineering or computer science. If you’re interested in taking advantage of this projected boom, you will need to pursue a Career in IT. You can either earn your degree from Online Computer Schools, or campus based Computer Training.

Computers and information technology is a part of our daily lives, and new technology is being developed at a fast pace. Computer Training is needed to help expand new computer software systems and to include new technologies and applications. The skills needed for Careers in IT change all of the time reflecting changes in technology and the growing needs of companies. Computer software engineers research, design, develop, and test operating systems-level software, compilers and network distribution software. They work with medical, industrial, military, communications, aerospace, business, and scientific and general computing applications. Software engineers set operational specifications and formulate and analyze software requirements

Computer engineers need the skills to create functional and technical design qualifications for software development. They must also have solid programming skills, and be familiar with data types, syntax and control structures. Along with the ability to correctly analyze information, software engineers also need to be able to fix multifaceted application glitches and be able to produce quality requirement specifications, design documents and test plans. Problem solving and working as a team are also necessary parts of working as a software engineer.

Now is the time to earn a Computer Degree in a computer-related discipline, as it is required for most software engineering positions. Growth in the technology field will be driven by the rapid growth in the technology sector. Demand for careers as a computer software engineer is expected to grow as computer applications continue to expand.
