Beam's second law emphasizes the significance of prototyping in reducing errors in requirements and design, particularly for user interfaces (L 3). Meanwhile, Davis' law points out that the value of a model depends on the perspective, as no model is universally optimal for all purposes (1_4). The initial software development methodology to be employed is the Waterfall Model. For the second methodology, any choice can be made except for the Agile Methodology and the Rational Unified Process (RUP). For both methodologies, the following tasks should be fulfilled: 1. Provide a personal interpretation of each law and support it with a practical example. Arks' Glass Law asserts that requirement deficiencies are the primary cause of project failures. He emphasizes that gathering project requirements is the initial step that leads to successful project completion. Robert Glass conducted research

on failed projects, which ultimately led him to make this statement. For example, consider the case of 'Hydrated airport' and their luggage handling system. The requirements for this system were incomplete and not useful. To rectify this issue, three different luggage handling systems were developed: one for each major airline and another for all other airlines. Beam's First Law states that errors are most common during the requirement and design stages and become more expensive to resolve later on.

In the process of collecting requirements and developing a project, errors are commonly made. Beam's first law identifies that the most frequent errors occur during the requirement and design stages, often due to incomplete or poorly managed requirements. Another principle, Beam's second law, states that prototyping can help reduce requirement and design errors.

ultimately lead to failure, we can see how Beam's second law can play a role in reducing such errors in requirements and design. Additionally, Davit's Law emphasizes the extensive use of modeling to represent actual or planned systems. These models can take various forms, such as mechanical, hydraulic, electrical, graphic, or arithmetic. Models serve as valuable tools for describing systems and can be transformed into visual representations. They study the static structure of system objects and utilize the logical structure of data.

Now, your task is to provide a comprehensive and personalized description of each software development methodology. Make sure to use your own words, and feel free to utilize diagrams, examples, or machine learning (ML) techniques to assist you in this endeavor. This task is worth 8 marks.

Starting off with the waterfall model, it is a sequential development approach where the development process flows steadily (similar to a waterfall) through different phases like requirements analysis, design, implementation, testing, integration, and maintenance.The waterfall model, which is a traditional engineering approach used in software engineering, emphasizes planning, time schedules, and target dates. It involves dividing a project into sequential phases with some overlap and kickbacks allowed between phases. The model also emphasizes the implementation of an entire system at once. However, the waterfall model has received criticism for causing delays and exceeding budgets in various large-scale government projects.
