Agile promotes iterative delivery and design as go because of which many organizations are given a hand to agile and developers are doing architecture as they go into their iterations. Without proper architecture we will create silos and redundant …show more content…
As stated by Togaf documentation, Architecture is classified as • Business Architecture • Data Architecture • Applications Architecture • Technology Architecture The combination of Data Architecture and Applications Architecture is also referred to as the Information Systems Architecture (The Open Group, 2011). Problem: It is very important to delivery software faster to the market and in most sophisticated manner. Agile has provided a promise faster to market and allows customer collaboration and agility to take change in requirements which facilitates development and delivery of product which is more up to date with stakeholder requirements. This provides biggest benefits of faster market, Agility and welcome to change. However Agile promotes smaller cycles of development and it needs features to be delivered iteratively. Agile promises faster and iterative delivery of project whereas Architecture provides foundation on which a software can be developed. While building complex software it is very important to define architecture properly. Modular approach and reuse makes it more complex increasing the need for
Agile processes do not devote much time up front to formal system specifications, but rather relies on continuous communication with the customer throughout the development process. The process accounts for the fact that needs often change or cannot be fully developed early on and is flexible to this. (+)
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
Using the Agile approach enabled us to organize the software project into chorological order from the User Requirements to the End product. The requirements were formed by meeting our client Fernando on regular bases discussing the requirements of the program. He would assure
“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.
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.
Both Agile and Waterfall models work with the same project and programmatic building blocks, such as scope, cost, schedule and
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 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 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
In building architecture the design is hard to change once it is set up. It is also more time consuming to change and more costly. The last aspect is the scheduling aspect. In software architecture one can schedule a project to be done in as little as one month depending on the project. Within the building architecture the scheduling is more time consuming and could take up more time depending if the stakeholder is approved for certain aspects of the building. In the building architecture one needs to take into consideration the scheduling when it comes to the inspectors. There are times when they are able to go and let the stakeholders know what passed and what did not. In software architecture the program will flag where the program is, making it easier for the programmer to go back and check on the spot when running the program. In the diagram below one can see the aspects as well as the differences in both software and building architecture.
Future State Enterprise Architecture Reference Model: It is needed to execute on the proposed business strategy
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
The top reason for adopting an Agile software application development approach is that it promotes a culture of collaboration and continuous feedback that concentrates on early delivery of superior products that meet important end user requirements. Agile software development is in use by many organizations and has been accepted not only as a method of developing software but in project management as well. This business case will outline the justification for Company “X” to move towards using the Agile development method and help guide management to evaluate and consider this option. An article related to the Agile method of software development was perused in preparation for this business case. The article examined is titled “Agility in Context” [1] (Hoda et al, 2010). This article along with my prior employment experience with Company “X” has helped provide the context for this business case.
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
