Introduction
Software engineering involves the methodical and disciplined approach to developing software products (Lehman, n.d.). Software Engineering develops and maintains reliable software systems that exhibit several features. Such features include; affordability, completeness, scalability, portability, integration, and dependability. The interpretation is that such systems must satisfy all user requirements as defined by the users. Such characteristics are important in meeting the organization’s objectives. The result of software engineering, therefore, is an efficient and reliable software system.
The precise definition of functional and non-functional requirements forms one of the main sections in the software development lifecycle that presents a challenge to developers. Definition of such requirements is essential for meeting both business and system performance objectives. Software requirements detail the main functions that the system must aim to fulfill. They represent the user’s expectations of the real-world system features (Mishra and Mohanty, 2012). Usability is the main feature of any software system under development that demonstrates the system as understandable and usable to the users under specified conditions. Challenges encountered in the different phases of the software development cycle, if not properly managed, may lead to poor usability in software systems a feature that significantly contributes to software failure.
Types of Requirements in Software development
Requirements form the basic functionalities that any system under development must satisfy in order for it to be a success. The two main types of requirements in software development include:
a) User requirements: these describe the services provided by the system including the...

...Software Engineering 1.) What does the term requirement mean? Explain the process of determining the requirement for a software system.  ‘Requirements’ suggests that there is someone out there doing the ‘requiring’ – a specific customer who knows what she wants. In some projects, requirements are understood to be the list of features (or functions, properties, constraints, etc.) Demanded by the customer. In practice, there is rarely a single customer, but rather a diverse set of people who will be affected in one way or another by the system. These people may have varied and conflicting goals. Their goals may not be explicit, or may be hard to articulate. They may not know what they want or what is possible. Under these circumstances, asking them what they ‘require’ is not likely to be fruitful. 2.) Describe the various steps of requirement engineering? Is it essential to follow these steps?  Requirements engineering is an important aspect of any software project, and is a general term used to encompass all the activities related to requirements. The four specific steps in software requirements engineering are: • Requirements elicitation is the practice of obtaining the requirements of a system from users, customers and other stakeholders. • Requirements analysis encompasses those tasks that go into determining the needs or conditions to meet for a new or altered product, taking account of the possibly conflicting requirements of the various...

...A software engineer is a professional who is skilled in various fields when it comes to software development like analyzing software requirements, handling and modification of software design to make it better in quality, price and running speed. Basically, a software engineer analyzes how a piece of software can be improved and decides how that can be improved. In this process he may or may not write a lot of computer code. Either way he must be familiar with different code languages so that he has an ability to review different kinds of software. A software engineer often work as a part of team to deal with design, planning and testing of software so that the end result would be in developing required functioning software. When working with a client, a software engineer will typically evaluate the client's needs, then design, develop and test computer software in order to meet those needs. During this process they create the detailed sets of instructions, called algorithms that tell the computer what to do. Software engineers are often more concerned with developing algorithms and analyzing and solving programming problems than with actually writing code. A software engineer need not just be a developer. Many software engineers work for Multi-nationals. They are required in the fields of applied mathematics, science, research and development (government organizations), teaching professionals in the field of study. Now-a-days various software engineers decide to work as...

Software Engineering for Computer Games

...LITERATURE REVIEW ON SOFTWARE ENGINEERING FOR COMPUTER GAMES Name: Course: Date Page 1 Abstract Games have often been very common in the past period of time, but with the discovery of computer games, they have penetrated. In spite of the third vista to computer games which is verifiable, it pertains to investigating what characteristics those who play such games anticipate from the gaming using the computer. Permit us state the meaning of a computer game as a play which is undertaken with an aid of a computer program. This meaning still leaves behind some flexibility because it does not imply that the whole game happens in the computer. For instance, Chess may be played on the computer screen and on a true-globe board, heedless to whether the one who objects to the play is a computer application. Huizinga in his classic work defined play as ``an activity which proceeds within certain limits of time and space, in a visible order, according to rules freely accepted, and outside the sphere of necessity or material utility. The play mood is one of rapture and enthusiasm, and is sacred or festive in accordance with the occasion. A feeling of exaltation and tension accompanies the action, mirth and relaxation follow``. A lexicon likewise states the meaning of game as `‘a universal form of recreation generally including any activity engaged in for diversion or amusement and often establishing a situation that involves a contest or rivalry’`. Besides,......

Problems of Software Engineering

...Aneshia Price English 1101 Paper 3 Draft 2 Problems of Software Engineering The world of software engineering is a dynamic one. There are many benefits of the field including high rate of pay and wide availability of jobs. However, there is always a downside of everything great. Besides the years of rigorous training, there are problems once you enter the field. If you ever need to change jobs, it will be difficult due to the amount of competition (Enriquez). You also have to constantly keep up with changing technology, if you do not keep up the pace, you can easily be replaced. Also, it is a major challenge to just secure a job with a major company like Google. The hiring process is not like a “regular” job. To get a good job in this field, you must be the best of the best and be able to maintain that status to keep your job. There is also an incredible amount of stress related to this job. While it may seem like a cozy inside job, there are many stressor within the software engineering career. The major issue with becoming a software engineer resides in the reason that also makes the field such a successful one. While jobs are plentiful in the field due to changing technology, this also makes it very easy to lose your job. There is always someone waiting to take your place, and since many software engineering jobs allow you to work from home, you have to deal with international competition. Companies are always looking for someone to do the job for less and,......

...interface design or user interface engineering is the design of computers, appliances, machines, mobile communication devices, software applications, and websites with the focus on theuser's experience and interaction. The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals—what is often called user-centered design. Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design may be utilized to support its usability. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs. OBJECTIVES: The main objectives of user interface design are: * To suggest some general design principles for user interface design * To explain different interaction styles and their use * To explain when to use graphical and textual information presentation * To explain the principal activities in the user interface design process (interaction activities) * To introduce usability attributes and approaches to system evaluation USER INTERFACE: * System users often judge a system by its interface rather than its functionality * A poorly designed interface can cause a user to make catastrophic errors * Poor user interface design is the reason why so many software systems are never......

Introduction to Software Engineering

...INTRODUCTION TO SOFTWARE ENGINEERING Have you ever noticed how the invention of one technology can have profound and unexpected effects on other seemingly unrelated technologies, on commercial enterprises, on people and even on culture as a whole? This phenomenon often called:- “THE LAW OF UNINTENDED CONSEQUENCES”. Today, computer software is the single most important technology on the world stage, and software is also a prime example of the “Law of Unintended Consequences”. No one could have foreseen that over the past 50 years, software become embedded in system of all kinds. i.e. Banking, Medical, Transportation, Entertainment and so on. And if we believe in the Law of Unintended Consequences, there are many more effects that we can not yet predict! As software’s importance has grown, the software community has continually attempted to develop technologies that will make it easier, faster and less expensive to build and maintain high quality computer programs. Some of the Software technologies are targeted at a Specific Application Domain (e.g. Web site design and implementation). Others focus on a Technology Domain (e.g. O.O System and programming) and still these are Broad-based software Applications domain (e.g. Operating Systems such as Linux), However we have yet to develop a Software technology that targeted to all the likelihood of one arising in the future is small.

Artificial Intelligence and Software Engineering: Status and Future Trends

...Artificial Intelligence and Software Engineering: Status and Future Trends Jörg Rech, Klaus-Dieter Althoff The disciplines of Artificial Intelligence and Software Engineering have many commonalities. Both deal with modeling real world objects from the real world like business processes, expert knowledge, or process models. This article gives a short overview about these disciplines and describes some current research topics against the background of common points of contact. 1 Introduction During the last decades the disciplines of Artificial Intelligence (AI) and Software Engineering (SE) have developed separately without much exchange of research results. In AI we researched techniques for the computations that made it possible to perceive, reason, and act. Research in SE was concerned with supporting human beings to develop better software faster. Today, several research directions of both disciplines come closer together and are beginning to build new research areas. Software Agents play an important role as research objects in Distributed AI (DAI) as well as in agentoriented software engineering (AOSE). Knowledge-Based Systems (KBS) are being investigated for learning software organizations (LSO) as well as knowledge engineering. Ambient Intelligence (AmI) is a new research area for distributed, non-intrusive, and intelligent software systems both from the direction of how to build these systems as well as how to design the collaboration between ambient systems.......
