Introduction

For any project, it is important to have a goal that the project seeks to achieve. Therefore, for such a project, creating short term and long term objectives will help the developers to create a successful product. Similarly, when creating software or systems, such as applications, the process should be guided by models that will assist in creating the desired product. These models have defined steps that guide developers in their progress, ensuring that the developers create a product that is worth the investment, while also serving the primary objective as desired (“6 Basic SDLC Methodologies”, 2014). These models are the Software Development Life Cycles (SDLC).

For the Information Technology (IT) specialization, the best SDLC models for projects mainly involve creating a system that solves a problem that is currently experienced in the IT sector. This development means that the industry is evaluated first for any problems, and an idea created from the existing problems. This idea is then set as the goal of the project. The stages of development of the system will vary depending on the chosen model. Choices for models largely rely on the size of the project and its effectiveness depending on the goal.

Regarding the previous project, the best SDLC model for development is the Spiral Model. This model’s steps are derived from other models to develop a less deficient model compared to those it derives its features. That is, the Spiral Model picks some steps from the Prototype Model and the Waterfall Model. The Spiral Model will help realize a more efficient IT system for this project since it is detailed from the identification, planning, development, implementation, and maintenance of the system. The model’s integration of features from the Waterfall and Prototype models further makes the system reliable since it reduces risks in development that would have arisen if one of the two projects is employed (Ghahrai, 2016). Moreover, the Spiral Model is suitable for large IT systems.

                                           Steps in the Spiral Model

The Spiral Model initially involves evaluating the existing IT system, to check for any disadvantages or problems in the system. With constant evolution in technology, the model may also involve evaluating whether the existing system is up to date technologically. The model’s next step will be developing a goal from the evaluation conducted. The goal aims to provide a better service for its users and a more efficient system for the developers (Sami, 2012). Regarding the project, the model involves developing a goal for the development of an IT system that overcomes most of the problems currently experienced in the system. For this step, this model requires much information to help formulate a clear goal that will be efficient for the developers and users. This goal is developed from proposals to the determined existing problems of the IT system.

The model’s next stage involves planning for the goal, setting short term objectives which will help the developers arrive at the goal within the shortest time possible. This is based on the SDLC step for defining the requirements for a new desired system. The planning stipulates schedules for the system created by the developers and the short term objectives. After a plan is drawn, the development of a prototype of the expected final system is started. The prototype is created based on the information collected during problem evaluation, corresponding to the step for SDLC to designing the proposed system ("Prototyping Model," 2005). This concept for the Spiral Model is incorporated from the Prototype Model. The prototype is then released to users for piloting. This stage will involve collecting feedback from users and involving information specialists to analyze the responses from the users. The developers may then, based on the reviews by users and professionals, redesign the prototype to fix the errors in the initial release ("Prototyping Model," 2005). This updated prototype is consequently released to the users for another review. The users and specialists again evaluate the system's effectiveness.

The Spiral Model emphasizes on developing a user-acceptable system, providing a system that is unique and satisfies the consumers’ needs. As a result, the model involves the iterative development of a prototype, until a final widely accepted prototype is got. The refined prototype is the most effective since users provide positive feedback on the new development.

The next step for the SDLC for this IT system is developing the new system based on the refined prototype. This stage borrows from the Waterfall Model, which integrates step-by-step development of the final system. This step-by-step process ensures that the final system is similar to the refined prototype as is expected ("System Analysis and Design," 2017). The final system is released to users as is required in the SDLC procedures. The proprietors may now educate the public on the new system, informing the users of the latest developments in the new system, and how to use the features. The new system is rolled out as far as the business would require, to ensure maximum coverage. The new system's primary goal should be ensuring the safety of online data and transactions, corresponding to reducing risks for users within the system. The system should further ease the users' interaction with services, which is preferred by many users, and he would require using the latest technology available. Moreover, based on the SDLC requirements, also incorporated in the Spiral Model, the system is inspected for any deficiency, and necessary corrections are made. Additionally, a maintenance schedule is developed for the system, to ensure that the system does not break down during its operation.

Although the project majorly relies on the views of users, the information specialists will help create the desired system. Although it may be initially costly, the Spiral Model is capable of creating such a project in the most economical way regarding long term effects.
