Software Development Life Cycle Essay

A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been

System development lifecycle is a model that contain a series of steps or stages that involved in the development of a project in other words System development lifecycle is a detailed process requiring careful planning, execution and management

The initial and most important step of the testing phase is creating the test plan. The test plan should include what features and functionality will be tested based on the confirmed requirements. The next step is unit testing or code review. Unit testing involves the QA person testing the code on their machine. Once code has passed the unit test, it will then be released to the testing environment for system testing. The QA person can then test the integration of the different modules of the code as a program rather than separate parts as well as to find and report bugs and any data inaccuracy. The next phase of testing is the user acceptance test. In this phase the users test the program for functionality and data accuracy. The test phase isn’t a linear phase, more of a circular, back and forth between the developers and the QA people. After all phases have passed, the next step would be to open a change

4. Development and Testing – This step involves using the final system design to acquire or develop the system. Testing of units, integration, performance, system, and acceptance are done to ensure system functionality and the sponsor’s requirements and that all segments/structures, communications, applications, procedures, and documentation are in place, tested, and integrated. End users are implemented to verify and thoroughly test that the system functions as required.

The third step is the design stage which involves the requirements for the design of the technology, and these include data layers, programming language, and the data services. This stage helps in implementing a design that highlights the coverage of the business logic that was analyzed at the previous stage. The next step is the coding which involves writing the sources of the actual code that will be used in the implementation of the business logic, the models, and the integrations of the services that had been generated earlier. The fifth stage is a testing step where testers such as beta testers are solving issues that arise out of the application (Petersen & Baca, 2009). However, this stage usually tends to repeat the coding stage so that there can be proper squashing of the detected bugs. The final stage is the operation stage where the application is considered complete and can be deployed. Besides, this stage involves maintenance and support in ensuring the application remains updated and fully operational (Petersen & Baca, 2009).

After the proposed system is analyzed and designed, the actual implementation of the system occurs. After implementation, working system is available and it requires timely maintenance.

There are many ways to develop an Information system, which is very complex. The systems development life cycle (SDLC) provides an overall efficient framework for managing the process of system development. Various organizations use information systems to support all kind of processes that a business needs to carry out its functions. There are different kind of information system and each has its own life, and system developer describe this idea as life cycle of system. During the life of an information system, it is first conceived as an idea; then it is designed, built, and deployed during a development project; and finally it is put into production and used to support the business. Projects during

SDLC stands for the systems development life cycle. It is a conceptual model used in project management that describes the stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application. There are five steps to the SDLC, which are planning, analyze, design, implementation, and maintenance. The Boehm- Waterfall Software engineering methodology relates to SDLC because it contains stages that hold stages of system requirements, software requirements, preliminary and detailed design, implementation, testing, operations, and maintenance. SDLC and the Boehm-Waterfall methodology are both very similar, however the Boehm-Waterfall is a more detailed methodology and also includes validation at each stage where SDLC does not have any of those advantages.

Process analysis is the systematic breakdown of the phases of a process. The first piece of the process is the initiation phase, where the business identified a problem in the human resources (HR) system. A proposal to develop software for the real-time integration of the HR system with multiple other systems of record was submitted to solve the problem. After the business approves the proposal, the next part of the process is system concept development. This phase of the software development life cycle (SDLC) involves collecting system boundary documentation that identifies the scope of the system, conducting a feasibility study and cost/benefit analysis, and developing a risk management plan (Blaha & Rumbaugh, 2005).

The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system. The systems development life-cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.

The waterfall model is the most common model of all software development life cycle models. It is very simple to understand and use. In a waterfall model, each phase must be completed before the next phase can start. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not the project should be continued. Here phases do not overlap with each other.

A Comparison of Software/System Development Methods 2 A Comparison of Software/System Development Methods The goal of this paper is to compare and contrast two articles on software/system development life cycle (SDLC) methods, identify how these methods are applied to my current company and which one I believe is the most valuable. My ultimate goal is to provide the reader with a thorough understanding of what the SDLC is, highlight two methods, and then provide a way forward within the United States Air Force (USAF) utilizing what I feel is the best method.

Abstract—At the end of 20th century software industry started booming. From then, not only it has never looked back, but it’s continuously growing at a very high rate. Customers always prefer quality software products and hence software quality is at the heart of any successful business that develops software. Software testing enables once to quantify the software quality and hence testing has become an integral and very important part of the software development life cycle. There’s this saying that “humans make mistakes all the time” which should enough to conclude that the software developed by humans needs to be tested of bugs and intended functionality to ensure a high quality product and hence Software Testing plays an important role

Software engineering provides the framework for building the high quality software. It integrates the various strategies, methods and tools for the software development. The revolution of software engineering offers the different types of software development models. It majorly ratifies the performance of the software through the testing and maintenance phase of the software.
