Agile And Software Architecture . Marching Together ..

The Architecture Vision is the early phase of Enterprise Architecture and provides high lever view of Product. This phase also supports Stakeholder Commutation by providing full architecture definition. This document shows contents of Architecture vision.

“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

Enterprise Architecture is an all-inclusive approach to managing the complexity of IT from a business viewpoint. A framework is used to help describe how to create and use an EA, in a manner that delivers business benefit in a cost - effective way. Each framework has a different approach to adding value to the business. These criteria will identify the ways an enterprise architecture framework adds business value, how adaptability and flexibility effect the overall adoption of an enterprise architecture framework, how the deliverables contribute to the success of an enterprise architecture, how does each framework take a strategic approach to reduce complexity of enterprise architecture, and how the framework encompasses the Software Development Lifecycle.

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].

Agile methods are one of the most recently conceived methodologies for developing software intensive systems. Agile methods refer to a family of methods that tend to favor working code over documentation, individuals over tools, collaboration over negotiation and thriving in volatile environments over following a plan ("Agile Manifesto" 2001). However, agile methods are not indicated for all projects; project managers, with organizational support, must decide if agile methods will provide the most benefit over conventional software engineering methods for developing new software intensive projects.

Agile development is a relatively new management framework for knowledge work projects, focusing on the socio-technical nature of project teams and creative collaboration (Gandomani & Nafchi, 2016). Software development is at the forefront of the transition to agile methodologies (Lechler & Siwen, 2017) and I am currently studying for the PMI Agile

“Enterprise architecture framework maps all of the software development process within the enterprise and how they relate and interact to fulfill the enterprises mission.”[1] Frameworks are conceptually created to eliminate conflicts in the development phase. An easy transition and systematic architecture are essential functions to process an enterprise. The following paper discusses TOGAF in detail, along with DoDAF and FEAF.

In conclusion, agile software development is a very exciting and useful approach, although some project suit agile more than others. The collaboration and visibility can provide a much better and rewarding experience for the team to develop software products. Over the last years, many companies dramatically improved their performances

Agile Development—an information systems development process that emphasizes flexibility to anticipate new requirements during development

Architecture is a long-term concern which takes significant amount of time, and this increased amount of time to market usually translates into reduced opportunity. One of the major reasons that software architectures are so often average is that architecture frequently takes a back seat to more mundane concerns such as cost, time-to-market, and programmer skill. Thus, business forces tend not to allow

Abstract: Software architecture is important because of communication among stakeholders, Design decisions for understanding software, transferable design of a system. Software architecture represents a common design of a system that most if not all of the system 's stakeholders can use as a basis for mutual understanding, negotiation, agreement, and communication. Software architecture manifests the earliest design decisions about a system, and these early bindings carry weight .It is also the earliest point at which design decisions governing the system to be built can be analyzed. Software architecture constitutes a relatively small, intellectually understandable model for how a system is structured and how its elements work together, and this model is transferable across systems. There are different types of architectural styles: Distributed architecture, data flow architecture, implicit asynchronous architecture, data centered architecture, hierarchical architecture and interaction oriented architecture. This paper compares all the architectural styles and aspects of comparison are category, styles, advantages, disadvantages, examples.

In a real world definition we can simply say that: “Architecture is a formal description of a system.”

As we saw throughout the last forty or so years is that computer systems frequently evolve and that developmental change is inevitable and software development is no stranger to this, which is where agile development or the term that some use agile software development comes into play. This is a concept that searches for alternatives to the traditional way of managing a project and based on the foundation that change is essential to software development. Throughout this paper, we will look at the reasons that brought about the change in thinking with regard to software development, discuss some of the key principles of agile development, methods under agile development and the benefits of the use of agile development. Let’s begin this document with a discussion into what brought about the change in thinking.

Software architecture is the designing and creation of a structured framework which comprises elements that meet the software requirements and allows
