what is software program engineering?

what is software program engineering? no person appears to understand. each person has an opinion, and every body consents that it is of the utmost importance, but there may be little consensus as to what it is. however earlier than addressing the above question, let us first answer the question: Why is it known as "engineering"?

it's far called "engineering" due to the fact early practitioners wanted to call it "software program physics," but that term became already in use. They wanted to name it software program physics due to the fact they believed that the procedure of manufacturing software program may be formalized with such rigor that it'd be on all fours with physics. certainly, texts from the '80s are populated with theories, derivations, tables, graphs, equations and formulae, reputedly in an attempt to seem mathematical and scientific in nature. inside a few years but, the inadequacy of these books have become clean, and the scenario changed rapidly, and contemporary texts incorporate virtually no formulae or equations. no matter that, the identify software engineering has been retained, authors claiming of their introductions that, e.g., "software program engineering employs engineering techniques, approaches, strategies and measurement." precisely what those engineering techniques, approaches, strategies and measurements are, is in no way said, and the books by no means confer with them after the introduction. Of route SE is an artificial technological know-how, whereas physics and chemistry are herbal sciences. however, if it is a real science, and authentic engineering, we should anticipate to find some type of system of laws and theories with experiments and predictions.

If we pick up an engineering e-book on how to layout an vehicle engine, we do no longer locate sections on the waterfall model or the spiral model that we discover in SE texts. we would anticipate to locate sections on pistons and cams, and we would now not count on it to contain sections on dashboard format or fee estimates. And but in SE texts we are able to find subjects like display screen format and cost estimates, and we additionally see topics like team control, human elements, risk control and person interfaces, amongst others. Such subjects are very essential, however they belong to regions like advertising, control, IT and psychology, not engineering. software program manufacturing could be very distinctive from engineering, and it takes a few imagination to see massive parallels among the two. A software engineer isn't any more an engineer than a novelist is a phrase engineer.

possibly the above observations are a bit harsh, and the hassle is simply verbal and the name is a misnomer, a remnant from an in advance time. this is unfortunate, due to the fact the name implies clinical rigor, and opens software engineering to the rate that it is a pseudo-technology flying below false colorations. we'd be better off if the name have been changed to "software manufacturing strategies" or a few such.

returned to the original question. there are numerous textbooks on software engineering on the market, and a survey of their indices and chapter topics exhibits that they may be very disjointed. One e book will deal with a topic as crucial, and the next e book omits it absolutely. approximately the only commonality to be found is the insistence that SE has some thing to do with engineering. that is due partially to the complicated, amorphous nature of software program production, and partially to a one-length-fits-all mentality. software initiatives and programmers vary highly, and a few require hugely special processes than others. Supposing that every one software packages can suit below the identical umbrella is a mistake akin to questioning that mechanical, electrical and chemical engineering can be lumped together.

To be sure, there are numerous areas of software program studies that are properly known as medical. Bearing this in mind, we have to re-name software program engineering, dividing it into (A) software theory/research, and (B) software program manufacturing strategies.
