The Software Development Life Cycle

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

If they pass the testing then they are progressed to the production area where they are finally put into the production and here the final system is set up.

The preferred methodologies for managing a software’s lifecycle are a major factor in deciding how a firm reacts to market demands. The major SDLC frameworks followed are the waterfall model, Agile methodology (scrum) and Kanban. We will discuss this answer

The acronym SDLC is explained as a software development lifecycle. The phases of the SDLC include analysis and definition phases, where the purpose should be determined, the goals that need to be accomplished, and a set of definite requirements. Establishing a comprehensive audit plan is integral in fulfilling the successful and quality financials for a business. This should be done at the inception of creating the company as well as routinely checked on a consistent basis. This used in accordance with the Sarbanes-Oxley Act will guarantee that the company has a sure way to mitigate the fraud opportunity that may occur during the time of day-to-day operations (Strayer University 2013).

In this article we are going to discuss the software development life-cycles. But first lets break down the software development part and the life-cycle part.

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

In this semester, we covered three SDLC’s waterfall, incremental, and integration. The waterfall model divided the process of software development into different steps and the next step could not be initialized until the current step was completed. Incremental development was more of an agile development, since the processes could interleave. Integration development relies heavily on reusable code, which focused into integrating the components into the system. GCC and CLANG strive to give users the latest and most recent updates of their compilers. Therefore, with both being updated so frequently, the waterfall model is not the best SDLC for either of these systems. However, GCC or CLANG could be either incremental or integration. Both

System engineering principles and techniques such as model building, simulation, estimation, and measurement are used to build software products through the Software Development Life Cycle (SDLC). The software development life cycle is a stepwise and systematic process where each step depends on the successful completion of the previous step all arranged in a sequential order.

Collecting the requirements from client and then analyze the requirements then design the document and prototype and then to the development of the code after that it releases to the Quality Assurance to identify the defects and then resolve the defects or bugs by the development team and retest by the Quality Assurance and then submit the process to the client and then to the user for collecting the feedback and enhancement from the customer then if necessary changes are again made by the development team which is again processed to the quality assurance team to identify bugs then the bugs should be resolved and retest by the QA team if the client is satisfied with the process that can be released to the market and we can eliminate most of the defects at the initial stage.

A systems development lifecycle (SDLC) is a term used to describe the process of planning, designing, testing and deployment of information system (Roebuck, 2012). A SDLC has three essential goals: to ensure the delivery of high quality systems, ensure strong management control throughout the project and maximize the output of systems staff (Massey & Satao, 2012).

Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1).

I selected this topic because it is vital to anyone who wants to develop software to understand the various types of software development models. Software development models guide developers from start to finish for any given project. They encompass areas of development such as research, planning, design, coding, testing, setup, and maintenance (Liviu, 2014, pg.39-40). Various software models exist so it is also important for developers to know how to select the proper one that will be the most effective for their particular project. Although many models exist, for this review I will focus on two of the most commonly used software development models, which are the waterfall model, and the incremental model. HOW EACH MODEL WORKS. In this

Software Development Life Cycle, (SDLC) denotes the process used by software industries to design, develop and test high-quality software. SDLC is also referred to as Software development process and aims at producing high-quality software meeting or exceeding customer’s expectations, or that reaches completion within cost and times estimation. A system is a set of intermingling or dependent components that form a unified whole; it is a term that can get used in diverse industries. Therefore, SDLC is a limited term that explains the phases of developing a software component integrating with other software constituents to develop the whole system. Software Development Life Cycle depicts the process to be followed by a software organization for a software project consisting of the detailed plan with a description of how to develop, maintain, alter, and replace a particular software (Davis et al. 1455). Typically, an SDLC consists of six development stages as listed below:

At the Trinidad Gas Company (TGC), software development is done using an adaptive version of the Waterfall Methodology and the US Department of Justice Systems Development Life Cycle. The stages used by TGC in this mainly Waterfall Method involves the Initiation Phase, System Concept Development Phase, Planning Phase, Requirements Analysis Phase, Design Phase, Development Phase, Integration and Test Phase, Implementation Phase and Operations and Maintenance Phase. This methodology is a predictable, rigid and sequential design process, which means, that as each of the nine stages are completed, the developers move on to the next stage. In this sequential process there also exists a stage gate between each stage. This stage gate is simply a review of the project status to determine if to proceed or not. However, the stage gate approach is not always followed on many of the development projects undertaken by TGC. A brief description of each stage is mentioned below:

The traditional approach to software development can be illustrated through the waterfall model which is time tested and easy to understand. The waterfall model approaches software development in sequential manner, completing one activity before the other. It brakes up project in stages: requirement analysis, design, coding and testing, operation and maintenance (see fig. 1 below).
