What Are The Advantages And Disadvantages Of Agile Software Development

The Agile Scrum methodology is quite different as it 's, "...characterized by continuous feedback and change, and a software system developed using ADM evolves continuously through short iterations" (Renuka Sindhgtta, 2010). Sindhgatta, Nanjangud and Sengupta use the words iterative and incremental which truly sums up this method. To summarize their full definition of an Agile Scrum method, it consists of small defined sprints that are generally predefined as far as how long they take and what they are meant to accomplish. After a sprint is complete it is tested and presented to a larger

Agile Development is one of the methodologies use in software engineering to help develops software. Today, there are a lot of different approach to Agile method. However, they all share the same value and principals. This method is value interactions over team and customer, workable software, and adaptable to change. Over the processes, documentation, contract, and plan. Agile developer also following 12 principle. 1, Their first priority is to delivery fast and quality software that will satisfy customer. 2, be adaptable to any change in requirement at any point in time, Agile development always

Cost and resource needs are higher for traditional than Agile due to Waterfall’s sequential development phase of all requirements determined in the beginning, software design and finally implementation of master design. The need for all information up front takes substantial time to gather and the sequential design does not allow for project changes as the flow enters into the programming stage. With Agile, costs remain low because there exists an incremental and iterative approach to the project, meaning less time is used to collect all requirements up front, the

It is a working method. It allows two developers work together on the same piece of code, or work on the same workstation at the same time. When a developer is editing the code and the other developer can examine the code. The developer who is editing the code called 'Driver', another developer called "Observer". In fact, two developers often change roles. In pair programming, "Observer" considers the direction of the work, make suggestions about improvement, or problems that may arise in the future. This allows the "driver" to focus their attention on completing the task.

“Agile” was first introduced in 2001, by a team of software engineers looking to improve their adaptiveness and responsiveness to ever-changing requirements. Not knowing where to begin, the team began by formulating principles, which they would use to guide their new development process. Which, in turn, lead to the creation of the Agile Manifesto, and thus a new methodology was born.

The Agile Methodology Principles makes the development much faster because the primary importance is given to the customer satisfaction and continuously delivers product. Even though requirements change at the ending phase the product is developed. The Agile development insist the self-organizing team which can create requirements, best architectures, best models. The Agile development promotes a distinct way of thinking to build things and methods to deliver continuous improvement of product. It facilitates to make best practices and decisions together. It a development to promote the adaptive planning, continuous improvement, evolutionary development and delivery, and required time to complete work. It encourages for rapid response to change in the whole development cycle. The project team prefers agile development to move in a creative and quick way. The project progress also depends on working software and project environment and support is provided and built by the individuals. They promote the sustainable environment. Constant attention is provided to the technical excellence and best models are given by the agile methodology. This principle helps the project team members

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

Scrum Agile Methodologies is the most popular of the methodologies. It is an outline that uses fixed sprints. Once a sprints has ended, a scrum team works together with a new one which starts until the projected is finished. The team consists of:

On the other hand, Agile methodology is a development method that promotes teamwork and flexibility throughout the life-cycle; it is a development method that supports using a small, cross functional team to provide software frequently in small increments on a regular cycle. It implements regular contact with employees and is more flexible compared to the Waterfall Method. There are several different Agile software development methodologies like Crystal Methods, XP, Dynamic System Development Model (DSDM), and Scrum, all examples are focused on flexibility and focuses on keeping code simple, testing

Agile values Individuals and Interactions over Processes and Tools. Agile emphasizes the importance of individuals having interactions and engaging in collaborative thinking for software design and development.

The organization would prefer minimized privacy of developers so that everything they do is visible to everyone else in the project. And they would also rather have their developers work on code than the documentation. Customer feedback is deemed important for the prototype presented and this is used to plan the next course of action.

The dictionary meaning of “agile” is “ability to move quickly and easily” and this is the key aspect of Agile approach. It is a team based, iterative approach to development that emphasizes on rapid delivery and completing all functional components while the client is kept involved as part of the development process (Lotz 2013).

Focus is kept on the recurrence of condensed work cycles and also at the functional product yielded by the outcome, but in waterfall technique only once chance is been given to the development team to keep the project aspects right. But under the agile technique each and every feature of development including the design, requirements, is thoroughly checked under its lifecycle (Mahfuj et al, 2012). There is always some time to steer in another direction if a team stops at regular interval say after every two weeks and re-evaluates the project done.

Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].

Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.
