Software Development : Systems Development

“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

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.

Agile development is used in a team of five – six developers which work closely together and interact with each other. Before the project starts user requirements are collected from the user. The scrum master will be responsible that the whole team works and also get the customer involved to get more feedback for the project. This is a very good approach because the developers can share their knowledge and learn new skills from each other. The team member should be highly skilled in order to work together to avoid any lack of skills in the development.

Agile techniques should be used to solve the current issues faced by the company as agile techniques normally being used by the software industry help the business to act in response under the unpredictable situations faced. In Agile methodologies opportunities are been provided to evaluate whether the project is under the direction all through its development cycle. All this is being accomplished with the help of regular tempo kept in work, and the teams must show a product which is having the desired potential.

There are many different methodologies when it comes down to software development. Some methods may be too complicated for a small business to use. Agile development is a methodology that works extremely well for small businesses, and focuses on the strength of people-centric viewpoint and collaboration. Some benefits of agile development are increased productivity, expanded test coverage, improved quality/fewer defects, and higher customer satisfaction. Some challenges in

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].

Unlike waterfall development methodology, agile foresees the documentation but is initially unwilling to adapt such as adding a lot new facets to the development model. Gabe, M. said, "Agile methodologies attempt to capture and use the dynamics of change inherent in software development in the development process itself rather than resisting the ever-present and quickly changing environment.". Demand of traditional methods complete and accurate requirement before the development; agile methods presume that change is strict, unavoidable and must be embraced throughout the cycle of product development. Cao, L. and Ramesh, B. believes individuals who fill those roles are much more important than the roles that people fill. Fowler also believes that each talented individual brings something unique to a team that are developing the system and disagrees with the application of engineering

If timing becomes a concern in the marketing process of the finished product , agile allows you to adapt and quickly release a more basic & adjustable version of the product to be built upon at a later stage.

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. In most Agile methods development cycles are limited by 4 weeks. Teams work in a high tempo, preferring to deliver not a spotless software increment but a workable build which can be shown to the customer and later modified according to the feedback. This helps to avoid spending time developing software with functionality which will be rejected by the

Compared to the agile, another famous software development mode called waterfall is driven by technique documents and this mode require the team to write a lot of requirement documents containing all the requirements to a certain software. It is written to allow people to understand what software should do. So the developers will develop the functions of software according to the documents strictly. But the agile software development just focuses on the necessary document. It is avoid taking a lot of time to write the requirement documents. Its opinion is that the face to face communication between the human is the most important thing. So the agile think the human is

The agile methodology results in actual workable software, brought to you in an incremental technique. That is certainly different to traditional, waterfall project procedures, where the client / user has generally to wait patiently till the very end to be able to test and obtain benefit from the software program.

The Agile methodology is an alternative type of project management, typically used in software development. It helps project teams respond to change and work iteratively. Throughout a project using the Agile

The way that software is developed has been rapidly evolving over time, going through many iterations, one genre of which is Agile software development. The Agile Manifesto1 was published in 2001, however the ideas behind it have existed and used since the early 1970’s when E. A. Edmonds published a paper that introduced the idea of an adaptive software development process2. Then in the 1990’s there was a rapid evolution of software development processes. This lead to the creation of scrum in 1995, extreme programming in 1996 and feature-driven development in 1997. Though they were devised before the Agile Manifesto was created, they now all fall under Agile software development. Agile software development methods are generally considered much better than previous methods, such as the Waterfall method, though it is still considered to be in its early stages with many issues3.

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.
