Reflection of software engineering in Software Development Lifecycle (SDLC)

The software engineering provides techniques to facilitate the development of computer projects. It deals with systematic and disciplined approach to the work and use of appropriate tools and optimum solutions for the problems to be solved. Software engineering uses the design principles and best practices for building quality software In a nutshell, it is the use of technologies and practices from computer science, design management and overall project management.
Software engineering is a rich and emerging field. We can consider software engineering as a three dimensional model where each dimension is concerned with a particular aspect. The first dimension contains tools and techniques required to develop software. The second covers all management principles required to organize software projects successfully. And third holds all non-functional attributes (security, portability, interoperability) required to develop an application. These are sometimes referred to as the ‘-ilities’

Another important aspect software engineering is people. It accommodates every person related to the project being developed. So software engineering deals with the management as well as association of people.
The major phases in software development process are:
1. Specification 2.Design 3.Validation 4.Evolution
These activities may differ by the type of project/system being developed as well as organization policies. So different process models have been evolved, and correct model is chosen that matches the type of project and organization.

...So following processes are performed for monitoring and maintenance:
1.To check the overall performance of website/ server and invaluable insights of the application, software manufacturers take help of external monitoring services such as PINGDOM which continuously monitor your website for downtime and send emails/alerts as soon as servers goes slow/inaccessible.
2. To reduce the code complexity, eliminate the code smells and improve the testability, refactoring is performed by maintenance team.
3. To sustain useful operation of a system in host/target environment by providing requested functional enhancement, repairs, performance improvements and conversions.
In a nutshell, Software engineering plays a major role in software development process model in developing systematic, disciplined approach to the development, operation and maintenance of a software.

    In programming, computer engineers instruct computers how, to do their jobs or desired functions line by line. There are many forms of computer software engineers. There are computer applications software engineers who analyse user needs and designs and then build, maintain, or perfect specialized utility systems or applications already within the system. Computer applications engineers have a multitude of computer programming languages they have to use on a daily basis. Generally the favorite languages used are C, C++, and Java. The less popular languages that are used are Fortran and COBOL. Software engineers may also also develop packaged systems, systems software, or even create personalized applications. Computer systems software engineers are responsible for designing the maintenance and construction of a company's computer systems, while also planning the systems future growth. Computer systems software engineers analyse the needs of each specific department while working with a company and advise the company on which technical direction to follow. Computer systems software engineers often help set up the technical systems of the company within the departments. The computer systems software engineers will also sometimes set up the companies intranets systems. Specifically the ones that link the company's computer systems with the organization and make communications between departments run faster and smoother. Computer

    Because of complexity and the way it (project) is too long each team member is assigned a task, making code for each programmer not to be too long. Both unit and module testing are accomplished here by software developers. The computer language like C++, Java, Pascal, COBOL and other programming languages is used for coding. On receiving system design documents, the work is divided in modules and actual coding is started. Since, in this phase the code is produced so it is the main focus for the developer.

    Software maintenance stands for modifications and updates done to the software after the delivery of software product. There are several different reasons, why software maintenance is required. Software needs to be updated regularly to keep it functional with the new and latest technology. Once software is developed, it does not mean it is the final product or perfect. Software may need to be modified or updated because of errors or new customer wants new features to be added to the software. There are also several other reasons such as market conditions, host modifications and organization changes. (Tutorialspoint 2015)

    A Computer Software Engineer develops software systems to be used by their clients, such as a website used to sell the client’s products. Although software engineers spend the majority of their time programming and testing the software, a key component to the success of a software engineer is the ability to write a thorough Software Requirement Specification (SRS). A SRS documents the requirements and dependencies needed for the software, prior to beginning any programming. Therefore, a Software Engineer must po The SRS is so important because engineers can have a wide scope of clients that they regularly work with.

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.

  • Software Development Case Study

    836 Words  | 2 Pages

    Software has become an integral component in the way organisations conduct business. The impact of and reliance on software within organisations is increasing (Pesola, Eskeli, Parvianeni, Kommeren & Gramza, 2008; Xu & Brinkkemper, 2007). Software development is becoming a global phenomenon as organisations have adopted networked development environments and have globally outsourced portions of their development activities (Valimaki & Kaariainen, 2008). According to Lacheiner and Ramler (2011) software development is a complex process as it requires interaction between diverse individuals, the creation of comprehensive software development documents and comprises interdependent activities. Kaariainen and Valimaki (2008) argue that as an outcome of increased competition, the ability to produce products as scheduled is important to any organisation. This has resulted in organisations investing in technologies and frameworks that manage and support their software development processes (Jwo, Hsu & Cheng, 2010). Application Lifecycle Management Technology (ALMT) is proposed as a solution for the management of software development activities.

    Becoming a Software Engineer is not the easiest of tasks. To become a Software Engineer you would usually major in Computer Science (CUnet 1). A Computer Science degree is the most common degree among Software Engineers. It’s the most common because it covers a broad range of topics that Software Engineers need to know for this occupation (U.S. Department of Labor 1). Software Engineer’s need at least a Bachelor’s Degree in Computer Science to get hired by companies. Even though Computer Science is the most common degree Software Engineer’s have, there are also other subjects that they major in (U.S. Department of Labor 1). It is recommended that while pursuing a degree to become a Software Engineer, students should participate in internships, and to participate in projects to be hired by companies once they are out of college (Career Focus 1). If a Software Engineer does not major in Computer Sciences, they will most likely major in Computer Information Systems, Software Engineering, or mathematics (CUnet 2). To become a Software Engineer liking math, and having an engineering sense is a must, liking math and being good at it will help significantly whi...
