Explain The Spiral Cycle Of Spiral Methodology

The system development life cycle is a formal four-step process that can be followed in order to identify a problem and solve it. The first step is

The first milestone will be concept approval. During this phase, feasibility studies and basic system concepts have been approved by the management. The project is on course to proceed according to the detailed requirements. The next milestone is requirements review. During this stage, requirement specifications are ready, correct, and approved for input to the design. The next milestone will be preliminary design review here the architectural design meets all product requirements. Critical design review will then follow. During this phase, the detailed designs are approved and suitable for the development of test cases. The next milestone will be the test plan review, which involves reviewing the test plan to ensure product features are satisfactory. The next milestones will be tested readiness review, system test review, operational readiness review, and operational product

There are many advantages to the spiral development model. Spiral Life Cycle Model is one of the most adaptable software development lifecycle models in use ("Spiral," n.d.). Development stages can be established by the project manager, according to the difficulty of the project. Furthermore, observing the project is incredibly simple and efficient. Every stage, including each loop, involves a assessment from worried people ("Spiral," n.d.).

The next step in the process is system analysis. This second stage involves gathering requirements, such as documenting the strengths and weaknesses of the current system, having discussions with the users to understand their roles and needs. This is an integral part of the life cycle as employees are the most important asset a company has. Baya, Gruman, & Mathaisel state, “information technology

After the designing process, we will move on to develop our prototype to making sure the system work well as a whole before we start to implement the production into work. During it working stages, a system engineering have to making sure the systems work well and helping the client or a customer with any issue occur.

Team Mates as you know that we have chosen the Requirements in System Development Life Cycle, so have came across the following stages in the Requirements in my research which will be posted below specifically under their requirements.

Once a tool or vendor is determined the design team will work on implementing the design. The design will be implemented as part of the project plan timeline and Smith will provide developer testing in addition to end-user acceptance testing. This ensures that the final product matches the goals of the system as laid out in the project plan. Once acceptance testing is completed the system will be implemented and the system will enter its training phase as indicated in the project plan.

One commonly-used business process methodology is that of the Systems Development Lifecycle (SDL). The steps of the method involve: defining the components of the proposed system; determining its requirements (interviewing users, determining existing processes); designing the system components (determining specifications and job definitions); implementing the system (building, testing, and/or converting the existing system) and then maintaining the system (by fixing failures and quality monitoring) (Noe 2010: 18).

A new system development cycle brings a process of building a good system with quality. A single incorrect step could create a huge mistake in the development process. Steps of developing a system begin with requirement gathering and analysis; basically brainstorm to check ideas to put into action for development. This could be assembled independently through personal documentation, but a lot of them could be acquired with the user participation through interviews of open-ended questions or a structured questionnaire. Next task is the system analysis to improve decision making in order to define in detail. This is broken down into smaller parts to help make it more manageable to develop, design, and test. A system design gathers

Figure 1-2 and figure 1-3 are similar because they both show how the cycle should be followed when analyzing a system. Figure 1-2 is different from figure 1-3 because the life cycle appears to be in order, but it is not. The specific steps and their sequence are meant to be used for a project that is consistent with management approaches.

Over the early ages of computers, speed of computers is literally getting faster and faster every day. System development methodologies have been constantly developing referable to changing technologies and new demands from the varied range of user communities. In fact, system development methodologies plays a widely major role in the corporate, industrial systematic world and are continuously used in developing and improving information systems and software. Baugh (1990) clarified that since the system development methodology is related to a standard of steps named to a system development methodology, analysis, formulated by the organization and directed to arise and back up their information. The establishment of a system development methodology should be added to a developer of system analysis and design of a computer-based information. Software development life cycle is a methodology for designing,

In 1970 Winston W. Royce created the “Waterfall Method” which eventually became very popular with managers due to the logical flow from beginning to end. Winston’s original design involved 6 steps; requirements, design, implementation, verification, and maintenance it was later on when people started to customize the design and changed the requirements phase into the idea phase or just split the requirements phase into planning and analysis. As we move into the future the Waterfall method is very popular in software development since it is ridged, systematic, and sequential.

Please Spiral model is similar to the evolutionary model with more emphasis on risk management. The diagrammatic representation of the model is in form of spiral having many loops. The exact number of loops of the spiral is not fixed. It may vary from project to project. Each loop of the spiral is called up as the phase of the software development process. Basically there are 4 phases of the spiral model – Planning, Risk Analysis, Engineering and Review & Reevaluation. Software repeatedly passes through these phases in order to reach the completion.

In iterative model the entire cycle takes place in multiple iterations. In the initial iteration the basic requirements are taken and the entire process takes place. So eventually in subsequent iterations the development takes place. This method is basically used to develop a system or a project using repeated cycles. Any improvement or changes to be done takes place in successive iterations. This model is highly recommended if working on a bigger project.

The Waterfall method was originally developed in 1970 by Dr. W Royce to assist with the development of software. It has survived to this day through adaption and revisions enabling it to be one of the most widely used models (Charvat 2003). Its namesake originates from the analogy of a waterfall flowing downwards with the model following suit, cascading towards completion (Balaji and Murugaiyan 2012) this is known as a serial lifecycle. Each phase (starting in the top left corner) within the serial lifecycle is completed before moving on to the next phase until the end goal is reached (see Figure 1). This kind of method suits projects that have clearly defined stage goals, outcomes or solutions that are highlighted in the initial strategy of
