Analysis And Design Of Using Sciences And Computing

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

The waterfall lifecycle was the first process model to be introduced and widely known. It is also known as the linear-sequential

Agile development refers to any development process that is aligned with the concepts of the Agile Manifesto, these are: (Agilemanifesto.org, 2016)

A new system development cycle brings a process of building a good system with quality. A single incorrect step could create a huge mistake in the development process. Steps of developing a system begin with requirement gathering and analysis; basically brainstorm to check ideas to put into action for development. This could be assembled independently through personal documentation, but a lot of them could be acquired with the user participation through interviews of open-ended questions or a structured questionnaire. Next task is the system analysis to improve decision making in order to define in detail. This is broken down into smaller parts to help make it more manageable to develop, design, and test. A system design gathers

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 a field where developers thrive to provide products faster, better and very inexpensive methods. “Agile Development” term used for several iterative and incremental software development methodologies. Each agile method is unique in its approach, they all impart a typical vision and core attributes. As matter of fact all the methods are fundamentally incorporate with each other and having a review system provides successive ways to enhance, refine and deliver a software system. The below figure represents the steps followed in agile development

Agile methodology for a typical software project or any in environment in which the requirements are unknown or change quickly. Agile focus toward teamwork, constant user feedback, continuous improvement, face-to-face meetings, constant cooperation, early and continuous delivery of working

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

3.. The Agile Methodologies which can be considered as many different project, in the software project.

This essay involves the comparison and contrast of the different methodologies used by programming teams. Among these methodologies are; System development life cycle (SDLC), Extreme programming and Agile methodology. Software development methodologies are the frameworks involved to structure, plan and control the processes used in developing an information system. The system development life cycle (SDLC) is a conceptual model which is involved in most project management and used for large scale projects with relatively large number of developers. A good example of SDCL methodologies includes; waterfall model. The SDCL takes a lot of time to produce complete products but of high quality. Agile methodology is a conceptual framework used also in project management and it is designed for small projects with few developers. Extreme programming on the other hand allow for communication with customers and by doing so it ensures interaction between developers and consumers in order to change as fast as the customers' needs and desires changes. Even though there different methodologies, agile methodologies seem to have a lot of advantages over the Extreme programming and system development life cycle. Since it combines a number of other methodologies to come up with a better way for developer to produce faster and change to as customers desires changes.

Agile is the management of incremental software development across cross functional teams. Learned from years of successes and failures, the agile philosophy centers on software development with an importance with self-organization, motivation, in addition to daily team interaction. It means being able to present working software instead of slides and documentation. Agile encourages customer collaboration throughout the entire process to allow developers to respond to change in a timely manner. The agile development process can be implemented by different developmental processes and is comprised of several key principles. With personal experience of the outcome of correct agile implementation; agile can have the opposite effect without

Agile methodology is an approach to project management and agile software methodology is not a one methodology but a set of methodologies which share common characteristics to achieve business goals. Before 1950’s project management have taken place in an informal way for many eras and after an ameliorating of formal project management methodologies began to be defined and swiftly spared through the industry rather than traditional methodologies. The traditional approach of project management identified a set of sequences of steps to be completed such as initiation, planning and design, execution and construction, monitoring and controlling and completion but not all projects will have every stage and some projects can be terminated before they reach completion. When it derived to IT industry in the past few years there’s been

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.

The waterfall model consists of five phases such as requirements, Design, implementation, verification and maintenance. The method is a sequential design process where progress is seen as flowing downwards in a steadily manner, each development phase has its own distinct goals. The model is similar to water flowing down a cliff it can only flow in one way and cannot go back up it is the same with waterfall development ,after a development phase is completed it proceeds to the next development phase you cannot go back.

A software development methodology is a structure imposed on the development of a software product. It is used to structure, plan and control the process of developing an information system including procedures, techniques, tools and documentation aids. A wide variety of methodologies have evolved over the years, majority aggress that all these methodologies are distinguished into two categories – Heavyweight or Lightweight. Heavyweight methodologies are also known as traditional methodologies which approach system development with standard, well-defined processes such as Waterfall, Spiral and Unified Process. Lightweight methodologies
