Chapter 3 Agile Methodology3.1. OverviewAgile software development is a group of software development methods based on iterative and incremental development, in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-bound iterative approach, and encourages a rapid and flexible response to change. Agile development is chosen when the requirements are unclear. This is why it is chosen for projects where the risk rate is high. Agile software development is best for projects where the project can be divided into mini projects and these mini projects are completed by going through the design, coding and testing phase. The results of these iterations gradually clear the requirements. Customer feedback also clarifies the requirements. This is why most companies use agile development methodology because it has the ability to adapt to difficult situations and chase strict deadlines. The Agile method is used throughout the software industry. Most developers are aware that Agile methodology is best for them. Most software development projects change right during the development process. This is why agile methodology is best for these projects. There is room for change in them. Software developers follow these methods and that is why they have further modified them according to the different types of projects they face in their development time.3.2. Factors3.2.1. The nature of the ProjectAgile methodology is used where the requirements are unclear and ambiguous. This is because...half of the card......crystal, magenta crystal and blue crystal. There are different stages, which are followed in different types of crystalline methodologies. In the Crystal Clear method, documents, people's roles and process are followed. It is better for companies where all employees are sitting in the same room. This highlights the importance of collaboration and coordination between team members. It is obvious that if people discuss the design, priorities, problems and possible solutions in the same room, it would affect the overall performance of the team. It will improve their performance and their technical understanding of the project. This is why companies doing small projects that follow the Crystal Clear methodology get the most out of it with the help of this project-related communication and collaboration..
