The evaluation and risk analysis stage

This model includes four stages, the first of which is the Identification stage, where information and labor market requirements are collected, and as the project progresses and exits from the initial spiral to the final one, the requirements for the system and units are also determined. All this through direct communication with the customer. The design phase includes designing the program logically and geometrically, in addition to the concrete designs of the products, arriving at the final design in the last circle.

To reach the testing stage


The construction phase is where the program is written in each iteration or spiral so that it is presented to customers for evaluations and suggestions. With each spiral passed, the picture becomes clearer regarding modifications and requirements for the South Africa Email List final program. The evaluation and risk analysis stage: In this stage, the feasibility of applying the program and potential administrative risks such as cost, etc. are defined and evaluated, then we move to the second iteration. These are four models used in software design and development that show the magnitude of this field. Iterative model Using this model, a large software engineering project is broken down into smaller parts. For example, each feature can be dealt with separately. Once the first software development steps in a project are identified, each part undergoes all stages of software engineering development.



Waterfall model in projects

Email Data


The number and nature of the waterfall model’s stages varies depending on the particular interpretation, business, or industry. Despite the context, each stage of the model is completely dependent on the previous stage, and must be completed, checked. And approved before the next stage can begin. Waterfall model in software engineering. It has difficulty using the Korea Email List waterfall model in software engineering of the classical type.  The iterative waterfall model can be considered as an alternative to it, as the waterfall methodology contains. The necessary modifications to make the original model usable in practical software development projects. The iterative waterfall model is almost similar to the classic waterfall model except for modifications made to improve the efficiency of the software development process.
