Choosing Software Engineering Versus Software Development
Software engineering is a process of building programs by means of computer software that solves problems. The processes involved are process engineering, software engineering and software systems engineering. Software engineering thus is the systematic applied engineering techniques to the designing of software. Software engineer works as an architect or engineer in a team who works on designing, implementing, testing and maintenance of the software.
The main benefit of software engineering is its contribution towards the creation of new applications. It uses both theoretical and practical aspects to solve new software related problems. The main areas where software engineering has made a significant contribution include aerospace, medical, financial, online shopping, transportation, digital information technology, manufacturing and information systems. This technology helps to develop new applications in all these areas.
There are many fields in which software engineering has made significant contributions. Some of these areas are communication and entertainment, computer science, computer programming, e-commerce, consumer product and service, hardware, multimedia, networking, personnel and information technology, manufacturing, education and even environmental protection. In all these fields, software engineering has given a new perspective to develop new software products. Thereby it has been instrumental in improving the quality of life.
A number of software engineering principles are used. A principle is a rule, like the one “a program x can only be implemented if the users defined a set of user requirements”. Another principle is said to be a “reduction” or “implementing” of user requirements. A third principle is said to be a “comparison and pairing” technique. A fourth principle is known as the “functional analysis” technique which compares two or more pieces of software application to check whether they satisfy user requirements. A number of guidelines have also been issued to keep software engineering principles in use.
The current software crisis is due to overuse of software, resulting in the overloading of the system with unwanted and redundant software, slowing its overall efficiency. According to the US Bureau of Labor Statistics, in 2021, more than 8 million workers worldwide lost their jobs as a result of software outsourcing. This alarming rate shows how crucial it is to use good software engineering principles in software projects and the consequent reduction in software engineering budget.
According to US Bureau of Labor Statistics, this crisis is mainly due to the excessive use of outsource workers to hire software engineers from countries like India, China and others that offer lower wages. Furthermore, many companies have shifted their focus from traditional engineering and design to include computer systems design, management and other functional areas. According to an estimate, in 2021, more than one hundred and sixty thousand workers in the US were employed in computer systems and information technology. This implies that over one hundred thousand workers are involved in information and software development occupations.
In the case of information and software development projects, the basic principle is to develop computer programs that satisfy business requirements without the involvement of technical staffs from the client’s end. However, due to the excessive number of outsourced software engineers, this principle is often ignored, leading to disastrous consequences. For instance, if a large business decides to use open source software, then the technical knowledge possessed by them would be minimal. As a result, they may end up writing erroneous or incorrect code that would prove fatal for the business.
On the other hand, using software development methodologies would require the participation of highly skilled IT professionals. The resulting products could either be successful or not, depending on their quality. In contrast, engineering projects result in producing efficient and well-designed products that serve their clients’ specific needs. Therefore, the choice between the two is primarily dependent on the type of business and the kind of product to be developed.
