Software Engineering Abstract. : The phrase ‘software engineering’ has many meanings. One meaning is the development of computer-based systems, for critical applications. This is not a solved problem. Failuresin software development have played a large part in many areas and in huge financial losses. Some of these failures have been caused to due to programming errors in the small sense—a program’s failure to satisfy a given requirement. Some told the reasons of failures lies in software engineering. Introduction : Software development should be based on “the types of theories and practicals that are traditional in the established branches of engineering.” Yet after forty years of currency the phrase ‘software engineering’ still denotes …show more content…
There are may reasons for such outcome. First, too many areas of software development are not specialised, and consequently have not developed the normal designs that are the indispensable basis of reliable engineering success This paper discusses these causes and their effects. Description : 1. Software Engineering Is about fixing the failures The aspiration to ‘software engineering’ expresses a widely held belief that software development practices and theoretical foundations should be based on those of the established engineering branches. Certainly the record of those branches is far from perfect. Failures of software projects and products seem to be the rule rather than the exception. These and the multitudinous similar failures reported in the Risks Forum are evidence, above all, of the lack of dependability.In the products of software engineering ,we are not astounded—perhaps we …show more content…
4. Areas of Software Engineering Requirement Over forty years ago there was much dissatisfaction with the progress and achievements of software development, and much talk of a ‘software crisis’. Although in those days the primary and central role of the physical problem world in a computer-based system had not yet become a direct focus of interest. Banking and Insurance were the 2 large industries which require Software Engineering as in these areas Softwares were required at large scale due to large work and rigorous work. Civil engineers do not design motor cars, electrical power engineers do not design bridges, and aeronautical engineers do not design chemical plants. Our historical failure to learn and apply this lesson fully is epitomized by the persistence of the phrase ‘software engineering’. Software engineering can be a single discipline only on the assumption, by analogy, that the established branches constitute a single discipline of ‘tangible engineering’. On the contrary: they do not. The very successes that we hoped to emulate depend above all on their specialisation into distinct
Some software systems have a relatively short lifetime (many web-based systems), others have a lifetime of tens of years (large command and control systems). Some systems have to be delivered quickly if they are to be useful. The techniques used to develop short-lifetime, rapid delivery systems (e.g. use of scripting languages, prototyping, etc.) are inappropriate for long-lifetime systems which require techniques that allow for long-term support such as design modelling.
The Software Development Life Cycle is seldom used at my place of work. Unfortunately, recent developments in its use are deemed confidential. Due to this fact, this paper will examine in general terms one of the projects we are undertaking right now while at the same time attempting to maintain our confidentiality.
4. Explain why change is inevitable in complex systems and give examples (apart from prototyping and incremental delivery) of software process activities that help predict changes and make the software being developed more resilient to change.
A software engineer, simply put, is a well trained and versatile engineer. Software engineers are different from programmers, though, in many ways. Software engineers are trained and versed in the true discipline of any engineer and are capable of creating software and new technology. Software engineers design, create, test, and perfect new technology to be used in the world today. Software engineers are capable of creating and building robots, computers, and revolutionary technology. A software engineer is someone who is absorbed in developing computer software and technologies. They analyse prefabricated software and even create new software, personalized software for individual clients. A software engineer uses mathematical formulas and
Generally, the software projects that failed are evaluated in terms of cost, time, human resources (employees involved in project), Objectives caused to start a project have to be changed. The failure of the software projects may happen at any level sometimes at designing phase, requirements phase, etc. Many researchers, summarized that the main reasons for projects failures are:

Gary Shteyngart’s memoir “Little Failure” retraces the journey of an immigrant from Soviet Russia to the United States, at a time characterized by the ideological, economical and political power struggle between the two countries. This immigrant experience, as with many, is rich with historical stories and cultural contradictions, giving the reader insight on where the author comes from and his new surroundings. However, as Shteyngart’s tale progresses, the real Gary is gradually exposed, enabling us to understand him beyond his immigrant status. Though Shteyngart’s permanent move from Leningrad, Russia to the United States plays a crucial role in the definition of his identity, the author is more than your typical immigrant split between
It is a requirement that every major software development and implementation project includes three key stakeholders. These are enterprise customer, system integrator and software vendors. Most failures of the systems are contributed by these three stakeholders.

A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.

The software industry is one of the great catalysts of economic growth and job creation.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

... things that software engineers need to learn, if you do not learn these things you will be at a disadvantage and be limited to what you are capable of. The rapid growth will open new jobs for the upcoming generations of software engineering. Software engineering is a hard but rewarding career, but in the end it helps others accomplish things that would not be possible 50 years ago.
