When To Use the Agile Model?

What is Agile Model?

The Agile Model was primarily designed to help a project adapt quickly to change requests. So, the main aim of the Agile model is to facilitate quick project completion. To accomplish this task, agility is required. Agility is achieved by fitting the process to the project and removing activities that may not be essential for a specific project. Also, anything that is a waste of time and effort is avoided. The Agile Model refers to a group of development processes. These processes share some basic characteristics but do have certain subtle differences among themselves....

Principles of the Agile Model

To establish close contact with the customer during development and to gain a clear understanding of various requirements, each Agile project usually includes a customer representative on the team. At the end of each iteration stakeholders and the customer representative review, the progress made and re-evaluate the requirements. The agile model relies on working software deployment rather than comprehensive documentation. Frequent delivery of incremental versions of the software to the customer representative in intervals of a few weeks. Requirement change requests from the customer are encouraged and efficiently incorporated. It emphasizes having efficient team members and enhancing communications among them is given more importance. It is realized that improved communication among the development team members can be achieved through face-to-face communication rather than through the exchange of formal documents. It is recommended that the development team size should be kept small (5 to 9 people) to help the team members meaningfully engage in face-to-face communication and have a collaborative work environment. The agile development process usually deploys Pair Programming. In Pair programming, two programmers work together at one workstation. One does coding while the other reviews the code as it is typed in. The two programmers switch their roles every hour or so....

Characteristics of the Agile Process

Agile processes must be adaptable to technical and environmental changes. That means if any technological changes occur, then the agile process must accommodate them. The development of agile processes must be incremental. That means, in each development, the increment should contain some functionality that can be tested and verified by the customer. The customer feedback must be used to create the next increment of the process. The software increment must be delivered in a short span of time. It must be iterative so that each increment can be evaluated regularly....

When To Use the Agile Model?

When frequent modifications need to be made, this method is implemented. When a highly qualified and experienced team is available. When a customer is ready to have a meeting with the team all the time. when the project needs to be delivered quickly. Projects with few regulatory requirements or not certain requirements. projects utilizing a less-than-strict current methodology Those undertakings where the product proprietor is easily reachable Flexible project schedules and budgets....

Advantages of the Agile Model

Working through Pair programming produces well-written compact programs which have fewer errors as compared to programmers working alone. It reduces the total development time of the whole project. Agile development emphasizes face-to-face communication among team members, leading to better collaboration and understanding of project goals. Customer representatives get the idea of updated software products after each iteration. So, it is easy for him to change any requirement if needed. Agile development puts the customer at the center of the development process, ensuring that the end product meets their needs....

Disadvantages of the Agile Model

The lack of formal documents creates confusion and important decisions taken during different phases can be misinterpreted at any time by different team members. It is not suitable for handling complex dependencies. The agile model depends highly on customer interactions so if the customer is not clear, then the development team can be driven in the wrong direction. Agile development models often involve working in short sprints, which can make it difficult to plan and forecast project timelines and deliverables. This can lead to delays in the project and can make it difficult to accurately estimate the costs and resources needed for the project. Agile development models require a high degree of expertise from team members, as they need to be able to adapt to changing requirements and work in an iterative environment. This can be challenging for teams that are not experienced in agile development practices and can lead to delays and difficulties in the project. Due to the absence of proper documentation, when the project completes and the developers are assigned to another project, maintenance of the developed project can become a problem....

Conclusion

Agile development models prioritize flexibility, collaboration, and customer satisfaction. They focus on delivering working software in short iterations, allowing for quick adaptation to changing requirements. While Agile offers advantages like faster delivery and customer involvement, it may face challenges with complex dependencies and lack of formal documentation. Overall, Agile is best suited for projects requiring rapid development, continuous feedback, and a highly skilled team....
