Model waterfall yang fokus kepada proses pengembangan perangkat lunak yang sistematis atau berurutan. So, there are Verification phases on one side of the ‘V’ and Validation phases on the other side. Table Advantages and Disadvantages of Prototyping Model. The spiral model is a risk-driven software development process model. (Diagram of Spiral Model described by Boehm) It is also known to be based on evolutionary development as the primary and important features are defined, developed and deployed first and then other necessary features are added with each the spiral or phases of the project. This model combines the features of the prototyping model and waterfall model and is advantageous for large, complex, and expensive projects. The next step in the cycle evaluates alternatives based on objectives and constraints. The developer loses focus of the real purpose of prototype and hence, may compromise with the quality of the software. It has the potential for developing the incremental versions of the softwares by implementing the iterativeness of the prototype model and controlled methodical of the linear segmental model. To explain briefly Spiral Model is a Model where after each phase it get tested and errors or mistakes are done by us are get handled. The number of cycles varies for each project and is usually specified by the project manager. If the user is not satisfied with the prototype, a new prototype known as operational prototype is developed. This process goes on until a perfect prototype is developed. The Spiral Model was first introduced in a paper titled “A Spiral Model of Software Development and Enhancement” in 1986 written by Barry Boehm who was an American software engineer. For example, developers may use some inefficient algorithms or inappropriate programming languages while developing the prototype. DIAGRAM OF SPIRAL MODEL ; 7 ADVANTAGES OF SPIRAL MODEL.

Risk signifies that there is a possibility that the objectives of the project cannot be accomplished. Helps in reducing risks associated with the software. The whole development process repeatedly passes through these stages… Selain itu, system analyst harus tetap memantau resiko yang akan terjadi seperti faktor-faktor yang dapat menyebabkan cost overrun (pembengkakan biaya). This Spiral model is a combination of iterative development process model and sequential linear development model i.e. Barry Boehm menjelaskan bahawa model spiral merupakan model yang sangat berguna untuk melakukan pembangunan proyek-proyek besar dan prosesnya dilakukan dengan memperhatikan resiko proyek sehingga pada akhirnya akan menghasilkan model proses yang tepat sesuai kebutuhan pengguna. The exact number of loops of the spiral is unknown and can vary from project to project. Spiral Model Phases: Activities performed during phase: Planning: It includes estimating the cost, schedule and resources for the iteration. The spiral model is also similar to the prototyping model as one of the key features of prototyping is to develop a prototype until the user requirements are accomplished. The primary goal of prototyping is speedy development, thus, the system design can suffer as it is developed in series without considering integration of all other components. Coding. Thus, this model is time consuming and expensive. The spiral model is similar to the waterfall model as software requirements are understood at the early stages in both the models. It is easier to test and debug during a smaller iteration. 3. Take a look at the following spiral model diagram: A spiral model is divided into number of framework activities, also called task regions. Additional Functionality can be added at a later date.
