A s the past decades have seen the automation of all the tasks in all the domains and computing systems have become more complex and are being implanted in the modern society, there is a persistent demand for developing efficient methodologies to software development and maintenance. There is a requirement of great extents of effort, time and money to plan and develop any viable software. It also involves people and their organization. Even the very minor pieces of software require numerous activities to be accomplished and can be considered as a project. Owing to growing competition, today's commercial circumstances have become very dynamic. Companies need to act very fast to varying needs of the market. Important developments have also taken place in the way software is proposed and developed. Thus, software engineering which deals with all these areas has become an individualized study from researchers. Software crisis symbolizes the recurring system development obscurities where software problems cause the system tasks to be delayed, expensive, and/or not receptive to the user’s needs and requests. Software Engineering is an engineering discipline which is concerned with all phases of software production from the early stages of system requirements through to maintaining the system after is has gone into use. Software can be developed to meet the various stages of reliability, security and response time. Productivity of software development varies greatly based on the level of performance required by the customer. Software, as a result, has to achieve certain distinctive functions needed by clients. To determine accurate operative requirements and characteristics of software to be delivered is a very crucial activity of sof... ... middle of paper ... ...es whether a product meets its reliability objective and is ready to distribute. A large number of software reliability models have emerged as people try to understand the characteristics of how and why software fails, and attempt to quantify software reliability. The paper presents a bio inspired computing technique of Swarm Intelligence known as the Ant Colony Optimization Technique to predict software reliability. The proposed method is employed into a TSP problem with different failure data sets to predict software reliability and the results of our approach are reported. And, thus, the focus of the discussion to be presented here is an ACO for discrete optimization that has been used to predict software reliability using the Travelling Sales Person Problem where failure data is given as input and the result is calculated through Musa Basic Execution Time Model.
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.
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
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).
1.0 IntroductionIn this report I will be concentrating on the failure of software systems. To understand why software systems fail we need to understand what are software systems. Software systems are a type of information system. This is because a software system is basically a means for hardware to process information. Flynn’s definition of an information system is:"An information system provides procedures to record and make available information, concerning part of an organization, to assist organization-related activities."Humans have been processing information manually for thousands of years, but with the vast increase of demand for knowledge this century has meant that a new method of information processing has been needed. Software systems have provided a new means that is much faster and efficient.
While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
As technology advances, employers ask for new skills. Computer software engineers must continue to learn such skills if they hope to remain in this field. To help them keep up with the technology changes, continuing education and professional development seminars are offered by employers and software vendors, colleges and universities, private training institutions, and professional computing societies.
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
This study proposed a rule base expert system combined with Likert scale measurement that will become a base for the software engineers in the selection of appropriate software development methodology for the project. In this paper we provide a tool that will help in the selection process of development methodology. The future work will include more development methodologies and more selection parameters.
Although risk management can be implemented in practically every type of project, this paper focuses mainly on IT projects. Risk management
It is well known that the team work is far better than performing a task individually. Such kind of practice plays a very important role in software engineering. A lot of things can be achieved together with the combination of diversified people, as they input different tactics and skills so that the main objective of a certain mission can be accomplished appropriately. Even though teaming up and working for a project is essential and helpful; there exist some issues that could bring interruptions and conflicts in the team.

Requirements engineering begins during the communication activity, continues into the modeling activity, and builds a bridge from the system requirements into software design and construction. Through requirements engineering, there is an examination of the context of software work performed. It is essential for the software engineering team to understand all requirements of a problem before the team tries to solve the problem. An identification of specific needs that the design and construction must address is also included. Further is a need for the identification of the priorities that guides the order for the completion of work. This i...

Software engineering encompasses various principles from both the computer science field and the computer engineering field to develop practical uses of software within hardware we use on a daily basis. With the passage of time, technology dependent on software has become increasingly prevalent. As a result, there will be a high demand for software engineers to sustain the eventual abundance of new and more complex computers.
Software engineering is important in today’s society because we use the products of software engineering almost daily. We use the products of software engineering in objects as simple as our car keys to objects as complicated as supercomputers. The past, present, and future of software engineering is quite interesting. This paper will provide information about this field of study and why software engineering is going to be around a while.
