Software engineering looks into designing and implementing software applications and also modifying them so that they are better suited to client needs. It is one of the most important aspects of software program development and is a must to be applied in any organization that has undertaken software program development activities. Though a basic architectural degree in computer science is enough to work as a software engineer, a better advantage would be to have a license. Within the U. K, it is the British Software Society that licenses software technical engineers. In Canada, they have the Professional Engineer (P. Eng) designation, though as per the law, there is no necessity to get 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 program engineering came about because of computing background. Problems such as the ‘software crisis’, ‘complexity barrier’ hindered progress which were within course of time resolved through various techniques that came to encompass as a whole.
While a software engineer also assumes the role of a programmer, the programmer will not take on the role of an engineer, which basically entails dealing with theoretical constructs of software and hardware development. There are many job domains and these include programmers, hardware managers, 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 plus which process information in an efficient manner. A point to be noted relating to this field is that though it includes programming, it also looks into factors such as understanding client requirements, designing rule and testing to ensure that the application adjusts to standards that have been set.
